Daily Discovery: Be a Noise Control Engineer – Quiet that Phone!

Pollution. We often hear about the different kinds, from air and water to light pollution. But have you ever heard of sound pollution? Sound pollution can have harmful effects on both our health and the environment. It is the job of Noise Control Engineers to design and test noise insulation technologies and sound-adsorbent materials to help limit the harmful impacts of noise and sound pollution. Try your own hand at being a Noise Control Engineer and quiet that phone!

Supplies:

Smart Phone
Box or container large enough to hold phone and surrounding
materials
Materials- A variety of should be gathered. Start with clothes, plastic bags, bubble wrap, blankets, rain jackets, and anything else that comes to mind
Song to play during testing
Pen and paper for recording

Instructions:

Once you have gathered a variety of materials it is time to begin! Start by picking only one kind of material such as t-shirts.
Begin playing that rocking song you chose.
Next, surround the phone with the t-shirts and place it in your container. Try to have the phone be positioned in the very center of the box with equal amount of t-shirt material on all sides. If the phone is touching one side of the container the whole experiment is off.
Close the lid and listen. Did the music get quieter or not? Go ahead and record with your pen and paper the material you used (t-shirts) and how successful it was in quieting the phone on a scale of 1-10. 10 being you can’t hear the music at all and 1 being no change in sound level.
Chose another material and repeat steps 1-4.
Repeat step 5.
Repeat step 5 again.
Now instead of using only one kind of material switch it up and try combining the materials together. Perhaps both t-shirts and plastic bags or bubble wrap and rain jackets. The possibilities are endless! Just don’t forget to record your results.
Once you are finished testing each materials and combinations of materials got back and check out your recordings. Which material did the best in canceling out noise? Why do you think that is? What other materials do you think might work better? These are questions Noise Control Engineers ask themselves.

Daily Discovery: Simple Machines – Engineering Challenge!

How can one person easily lift a 500 lbs. piano? We have the how and why behind the simple machines that help you do just that! Think like a mechanical engineer to create a design concept, build and test your own machines, and see what you can lift at home!

Mechanical Engineering and Simple Machines:
Mechanical engineering combines physics, material sciences, and mathematical principles to design, build and maintain machines and tools that help make our world move and improve the conditions the life.

Subdisciplines of mechanical engineering:
1. Mechanical Manufacturing Engineering: These engineers have the important job of understanding, and improving, product quality of complex industrial and infrastructure systems.
2. Mechatronic Engineering: These engineers create robot-type smart machines that can make their own decisions and be conscious of their surroundings.

Mechanical engineers work with highly complex systems and machinery, but can often involve simple machines in what they do. Simple machines have a few working parts that provide a mechanical advantage to make aspects of our lives easier. These include the wheel and axel, levers, pulleys, or an inclined plane.

How do they work?

A lever is a rigid bar resting on a pivot, used to help move a heavy
load with one end when pressure is applied to the other. There are three classes of levers, and we see examples of all in everyday objects!

A pulley is a wheel and axel that guides or changes the direction of a rope, or reduce the force needed to move a load. Engineers can even use multiple pulleys to increase the mechanical advantage! There are three types of pulleys: fixed, moveable and compound. Each wheel rotates appropriately with the rope being pulled to reduce friction and increase mechanical advantage.

Supplies:

Cardboard
Writing utensils
Glue or tape
Random objects of varying weights
Paper tubes
String or yarn
Sticks and rocks
Wire coat hanger
Spools

Instructions:

Find something in your house that you want to use as your load (an object to lift) this could be heavy or light.
Use what you now know about simple machines, and engineer a way to move or lift your object effectively.
Continue your research into other simple machines to assist in your design concept. Will you use pulleys, levers, wheels and axels, wedges, or maybe a combination?

Daily Discovery: Rocket Power – Engineering Challenge

Engineers design rockets that can leave our planet and travel through space! But how do they build spacecraft that can fly there? Through this balloon rocket demonstration, see firsthand how a jet engine works to propel rockets into outer space!

Supplies:

Balloon
String (fishing string or a fine, smooth string is preferred)
Drinking straw
2 supports to tie your string to – Chairs, a railing, and/or door knob work (make sure they are level in height)
Tape or glue dots
Tape measure or ruler
Pencil
Paper
Colored pencils (optional)
Clothespin or binder clip (optional)

Instructions:

To demonstrate how a rocket moves, you are going to make a balloon rocket. The balloon rocket is propelled, or caused to move, by the air rushing out the end. Think of the balloon as your rocket’s engine, or propulsion system, and the air inside as your jet fuel!
Begin with your straw. Straight drinking straws work best the best, but if you have a bendy straw, cut off the part that bends and keep the straightest segment.
Now tie one end of the string to a chair, railing, or doorknob. This is where your balloon rocket will fly to. If you would like to, draw a picture of a planet you would like to visit and tape your drawing to the chair or railing.
Thread the free end of the string through the straw. Tie the other end of the string to the other support (chair, railing, or doorknob).
Blow up the balloon to its maximum capacity, being careful not to pop your balloon! Hold the end closed. Don’t tie your balloon shut. Keep it pinched closed with the help of a friend, or you can use a clothespin or binder clip to keep it closed.
Attach the balloon to the straw using tape or glue dots.
3…2…1… Blast off! Let go of the balloon’s end and see how far it flies!
Use your tape measure or ruler to measure how far your rocket traveled on the first launch. Print the table below, or draw the table on your own paper to track your results. Write down the distance traveled for each launch, making sure to write down how much ‘fuel’ (air) was inside your balloon and the launch number.
Repeat steps 5-8 to launch your balloon two more times, for a total of three launches.
Repeat steps 5-8, but on step 4, instead of blowing up the balloon to maximum capacity, blow the balloon up to ¾ air capacity and repeat the launch 3 times. Follow the same procedure to launch the balloon with ½ air capacity and again with ¼ air capacity.
Compare the data from your launches. What conclusions can you draw from your data? Is the distance your balloon traveled related to how much air was in your balloon?

Daily Discovery: Engineering Challenge – Civil Engineers

Posted on April 27, 2020March 4, 2021 by Kristin Rush in Ages 6-8, Ages 9-12, Daily Discovery, Discovery at Home, Engineering & Math, Experiments, Teens

Daily Discovery: Engineering Challenge – Civil Engineers

You can live, work, learn, and travel thanks to the solutions of Civil Engineers all around you! Learn about what Civil Engineers do, go on a scavenger hunt to find their work in your own neighborhood or city, and put on your own Jr. Civil Engineering hat to see if your design can stand up to our Civil Engineering challenge!

Supplies:

Pencil & Paper
Ruler
Civil Engineering Scavenger Hunt Page (optional, included)
Assortment of noodles, toothpicks, mini-marshmallows, tape, string, sticks, recycled cardboard, index cards, foam, pipe cleaners, popsicle sticks—whatever you can find in your house or backyard!
Fan (optional)
Bucket of water (optional)
Pillow or extra cardboard and a few balls (optional)

What is Civil Engineering?

Have you ever driven on a road? Turned on the sink to get water? Traveled across a bridge or through a tunnel? Flushed your toilet? Swum in Horsetooth or another reservoir? Gone in a building? You can do all these things and more thanks to the work of Civil Engineers!

Civil Engineering is one of the many branches of engineering.* Civil Engineers are problem solvers who work specifically with infrastructure. They design roads, buildings, tunnels, bridges, dams, buildings, subways, and more—all the things that help us live, work, and travel! They also help design important systems you may not see, such as how to get water clean and into your house; where dirty water and sewage (the stuff that goes down your toilet!) go; and where to direct stormwater to keep your neighborhood or basement from flooding! Our cities wouldn’t be the same without Civil Engineers!

Your Turn!

Think: What kind of Civil Engineer would you want to be?
What are things you care about or enjoy? Animals, people, airplanes, cars, trains, building structures, traveling, taking care of our planet? Which type of Civil Engineer could work with the things you love? Think about what problems you want to solve? Which Civil Engineer could help you solve them? If you were a Civil Engineer how would you solve them?
Look: Find examples of Civil Engineering in your city or neighborhood. As you drive or walk around keep your eyes open! You can even use the scavenger hunt page included at the end! What do you find? A lot of examples? A few? What did you find that surprised you? Which examples would you like to learn more about?
Try: Do the activity below to become a Jr. Civil Engineer and see if your design can solve some of the problems and pass some of the tests real Civil Engineers have to deal with!

Create The Strongest Bridge:

One of the many things Civil Engineers design are bridges! And guess what? Every type of Civil Engineer you learned about earlier may be involved in bridge design and construction! (Can you figure out how?)

Your challenge: Using your available materials, design a bridge that can span at least three inches. Your bridge will not only have to cross the divide, but also withstand testing—wind, earthquake, load, and possibly even flood testing—to make sure it is a safe design to be built and used by humans. Follow the steps below to get building!

Engineers use something called the Engineering Design Process to come up with, design, and test possible solutions to problems. We’re going to use that to solve our problem today (see the whole process in the chart on the next page). First, we need to identify the problem or need. What is the problem or need we’re facing in this challenge?
Next, gather your bridge building materials (noodles, toothpicks, mini-marshmallows, tape, string, sticks, recycled cardboard, index cards, foam, pipe cleaners, popsicle sticks— whatever you can find in your house or backyard!) Set them in front of you so you know what you’ve got to work with!
The next steps of the Engineering Design Process are to imagine possible solutions and draw a plan. Think about how you might use the materials in front of you to solve the
identified problem. Remember that your solution will need to withstand testing! It will need to bear weight, stand in the wind, and stand in an earthquake. Once you’ve got an
idea grab paper and a pencil. Draw your idea and write some steps to your design (you can use the worksheet included at the end if you want!)
Now that you’ve got a plan build your bridge! This is the fourth step of the Engineering Design Process; you’re creating a prototype! Level up: Don’t use tape or glue in your bridge design!

Time To Test:

Once you’ve got your bridge built it’s time to test it! Testing is the fifth step of the Engineering Design Process. It’s ok if you’re nervous to test your design (A NASA Engineer once told me that even they’re nervous to test their designs)! You put a lot of work into it, but testing is the only way we can be sure our designs will work and keep people safe. Even if your design fails you learn important information!

Load

1. The most important job of a bridge is to get people and vehicles from one place to another. But people and vehicles are heavy! A bridge must be able to withstand load (that’s the weight of the bridge itself and the weight of anything it might hold). Choose a heavy object (such as a can or book, you might choose this before construction so you know what your bridge will hold). Place it on your bridge. Can your bridge hold the weight? What about your design do you think helped its ability to hold weight. What hindered it?Did anything break or fall off? If it broke than your bridge isn’t safe enough for the real world yet! Level up: How much weight can your bridge hold?

Wind

1. Weather patterns can also be load on a bridge! Bridges need to be able to withstand a variety of weather conditions…including high wind! Place a fan a few feet from your bridge and turn it on. Can your bridge withstand the wind? Did anything break or fall off? If it broke than your bridge isn’t safe enough for the real world yet!
Level up: What wind speed can your bridge withstand (turn that fan on high!)

Earthquake!

1. Bridges also have to be able to withstand unexpected events such as earthquakes (thank you Earthquake Engineers)! To see if your bridge can withstand an earthquake place it on a moveable surface (such as a pillow or cookie sheet), tape it down, and give that surface a shake! Can your bridge withstand the earthquake? Did anything break or fall off? If it broke than your bridge isn’t safe enough for the real world yet! Level up: Build your very own shake table!

Flood!

1. For a final, fun test see how your bridge holds up in a flood (warning: this one could destroy your bridge)! You’ll want to place your bridge somewhere where a flood won’t cause other damage (such as on a porch or in a bathtub). Tape your bridge down, fill a bucket of water, and dump it downstream of your bridge. Did your bridge withstand the flood? Did anything break or fall off? If it broke than your bridge isn’t safe enough for the real world yet!

How did your bridge(s) hold up? Where did they fail? The final steps in the Engineering Design Process are improve and redesign, and repeat! How could you improve your bridge? If you designed again what would you change? Give your improvements a try! Did your bridge preform better this time?

Share It!
We’d love to see your bridges and any other Jr. Civil Engineering Projects you might try!

Daily Discovery: What’s With Weather? – Forecast It!

Posted on April 22, 2020March 4, 2021 by Kristin Rush in Ages 6-8, Ages 9-12, Daily Discovery, Discovery at Home, Earth & Space Science, Experiments

Daily Discovery: What’s With Weather? – Forecast It!

One minute it’s sunny and the next you can build a snowman! We all experience weather, but what really is weather and how do we predict it? Learn about how meteorologists forecast the weather before building some forecasting tools and setting up a weather station of your own!

Supplies:

For Observation Journal:

Paper
Crayons/markers

For Barometer

Glass jar
Balloon or plastic wrap
Rubber band
Ruler
Straw
Tape
Scissors

For Thermometer:

Bottle
Rubbing alcohol
Straw
Marker
Food coloring
Clay or playdoh
Pan of hot water, pan of cold water

Instructions:

Make Your Own Weather Journal:

Meteorologists track weather over multiple days to make the best forecasts. Weather data over decades gives us information about a place’s climate. You can track the weather from your home! Use your observation skills and the tools below! Keep your eye out for other Discovery at Home tools you can add to your weather station. Over time you will be able to forecast the weather too!

Gather your supplies! You’ll need paper (or you can print the handy weather report sheets at the end of this pdf! Make sure to print double sided!) and a pencil/marker. If you want to make a book, you’ll need a stapler or hole punch and string too.
Fold your paper and cover paper in half. Place your journal paper inside the cover. You can use plain paper or print off our journal pages. Decorate your cover! Attach the journal pages to the cover using stapler or by punching a hole at top and bottom and tying together with string!
Fill out your observation journal! Try and fill it out at the same time every day to be able to make the most accurate forecasts. After a few days try forecasting the weather. Why did you forecast that? What data did you base your forecast off of?
Try some of the other activities included here!

Make Your Own Barometer:

A barometer measures atmospheric pressure. Atmospheric pressure is the weight of the atmosphere overhead! Meteorologists track atmospheric pressure because a change in atmospheric pressure means a change in weather. Weather is controlled by changes in air pressure—high and low pressure systems (remember these are represented by “H” and “L” on our weather maps!). High pressure causes air to flow down and fan out near the ground, keeping clouds from forming—so nice weather! When air pressure is low, air flows together and then upward where it gathers, rising, cooling, and forming clouds—stormy weather! You can monitor the atmospheric pressure in your town by building your own barometer! TIP: It won’t be exciting at first, but if you watch for several days, you’ll notice the pressure is changing without
you realizing it!

Gather your supplies! You’ll need a glass jar, ruler, straw, balloon or plastic wrap, scissors, tape, and a rubber band.
Cut the long end off the balloon. Cut a small slit in the end of the balloon.
Stretch the balloon so that it fits over the mouth of the jar. Make sure it’s nice and tight and secure with a rubber band. If you don’t have a balloon use plastic wrap. Make sure it’s not loose or saggy…we need our jar to be sealed nice and tight!
Tape the end of the straw onto the middle of your balloon lid. A longer straw will make the barometer more accurate. You can put two straws together by cutting a small slit in the end of a straw, squeezing it to make the end smaller, and slipping it into another straw.
Keep your barometer indoors and in a place where it won’t get bumped. Place a ruler behind your straw to observe it rising and falling.

Observe:

Observe your barometer for several days and record what you see in your weather journal. Be sure to observe at the same time each day. What do you notice? Does the straw point to the same place on the ruler each day? Is it rising and falling? What does that mean? Remember, a straw rising means increasing pressure— sunny and clear—a straw falling means decreasing pressure—cloudy and stormy!

Make Your Own Thermometer:

A thermometer measures temperature—how hot/cold the atmosphere is. Meteorologists report temperature using Celsius or Fahrenheit. In the U.S. we use Fahrenheit, but most other countries use Celsius. Temperature can tell us important things—for example it can’t snow until it’s below freezing (32°F)—but temperature is also relative (compared to something). A 70° day would feel chilly after a week of 90° weather, but hot after a week of 40° weather! Thermometers are some of the oldest tools we use to understand the weather. Try making your own thermometer and see what you observe!

Gather your supplies! You’ll need a clear bottle, water, straw, rubbing alcohol, food coloring, and clay (playdoh works too!)
Start by filling your bottle ¼ of the way with equal parts rubbing alcohol and water. Add a couple drops of food coloring. We’re using red like in a real thermometer. PRO TIP: If you’re not using a clear straw add extra drops. The darker the water, the easier it will be to see it in the straw. Mix in the coloring.
Form a small clay pancake (we’re using playdoh!) and poke a hold through for your straw. Be sure there is no clay inside your straw!
Stick your straw into the bottle. The end should be in the liquid but SHOULDN’T touch the bottom of the bottle.
Secure the straw at the top of the bottle with your clay. Be sure you have a tight seal. Pinch it tight against the straw but don’t crush it. Make sure
the top of your straw is poking out the top and is open to the air.

Observe:

Note where the water level IN THE STRAW is. Make a mark on the outside of the bottle. You can calibrate your thermometer by noting what the air temperature is (say how warm it is in your home) and noting that next to the mark.

Place your bottle in a pan of hot water. What happens to the water level in the straw? Label the level and temperature. What happens when you take your thermometer out? What happens to the level when you place it in cold water? Label that level and temperature.

Forecast It!

Use your new tools to set up a weather station! Observe the weather over the course of a week or two at the same time every day. What do you notice? What patterns do you see?
After a few days of data can you forecast the next few days of weather? Were you right?

Daily Discovery: What’s With Weather? – Rain

Posted on April 21, 2020March 4, 2021 by Kristin Rush in Ages 6-8, Ages 9-12, Daily Discovery, Discovery at Home, Earth & Space Science, Experiments, Poudre River Fest Daily Discovery

Post written by Heidi Fuhrman, Discovery Camp Coordinator.

Daily Discovery: What’s With Weather? – Rain

We’ve learned about forecasting weather, but what about one of the components of weather—rain?! Learn about precipitation and create your very own water cycle before building another tool for your weather station! (If you haven’t checked out our “What’s With Weather: Forecast It!” Discovery at Home you might want to start there!)

Supplies:

For Experiment:

Ice cubes
Pot & Stove top
Cookie sheet or pan

Glass jar
Plate
Ice cubes & water

For Rain Gauge:

Empty plastic bottle (2 liter soda bottle works best!)
Scissors
Rocks, gravel, or marbles
Ruler
Tape & Marker

Instructions:

Experiment: Make It Rain

Precipitation, including rain, is just one important part of the water cycle! The basics of the water cycle are evaporation, condensation, and precipitation but scientists who study our climate also think about how runoff from mountains, groundwater, plant uptake and more effect our water cycle! What can you think about that might effect where water goes and how it gets to the oceans? What might impact how it gets to the skies and back to us? Start by building your own water cycle!

Gather your supplies! You’ll need a pot, stovetop, ice cubes, a cookie sheet or similar pan, and an adult’s help!
Put your cookie sheet into your freezer. You’ll need to let it get cold for a few minutes!
While your cookie sheet freezes, take out a good handful or two of ice cubes and put them in a pan. What do you notice about the ice cube? What do you notice about water in its frozen form?
With an adult’s help, put your pan full of ice cubes on a stove burner and heat them up. What do you hypothesize will happen to the ice? What happened? As the ice warms up, the molecules water can move! It’s now a liquid! What do you notice about water in its liquid form? As the water gets warmer and warmer the water molecules can move faster and faster until they bump each other out of the pan! What you see isn’t smoke but water vapor! What do you notice about water in its gas state? Carefully, with your adult’s permission hold your hand way above the pan and see what happens. Is your hand getting wet?
Take your cookie sheet out of the freezer and hold it a few inches over the pan. You can put some extra ice cubes on top for good measure! What do you hypothesize will happen? What do you notice now? What is happening to the water vapor? Keep holding the cookie sheet there and watch the bottom where the water vapor is hitting. After a few minutes what do you notice? Is the water condensing? As the water vapor hits the cold cookie sheet it cools down and turns back into a liquid, condensing on the bottom of the sheet and falling back to the pot as rain!

You just made a mini-water cycle!

If you can’t use a stovetop, you can do this rain experiment a different way!

Gather your supplies, you’ll need a glass jar, hot water, a ceramic plate, and some ice cubes.
Pour your hot water into a glass jar and place your plate flat on top. What do you notice?
Wait a few minutes and then place some ice cubes on the plate. What is happening on the bottom of the plate?

Make Your Own Rain Gauge:

Meteorologists and other scientists track precipitation to better understand a place’s climate. Knowing how much precipitation has fallen in an area also helps them better predict droughts and floods. This helps farmers and keeps communities safe! NASA helps track precipitation using satellites in space, but meteorologists track it from the ground too! You can track precipitation in your neighborhood by building your own rain gauge to measure how much rain and snow falls in your backyard! Does more or less rain fall then you hypothesized? Add your rain gauge to the weather station you might have built from “What’s With Weather: Forecast It!” You can also track how precipitation your backyard gets in your weather journal you created with that activity or help out real scientists by checking out the citizen science opportunity at the end of this section!

Gather your supplies! You’ll need rocks or gravel, a marker, ruler, scissors, tape, and clear bottle. A 2 liter soda bottle works best, but you can also use a water bottle, juice bottle, or even an empty milk jug!
With an adult’s help, cut the top of the bottle or jug off, about 2-3 inches below the top. If you’re using a jug with a handle, be sure to cut above the handle.
To keep your rain gauge from blowing over or away fill the bottom with some rocks or gravel. Then Flip the top portion of the bottle over and fit inside. It should form a funnel! This will allow your rain gauge to better collect rain as it falls!
Tape the two bottle pieces together. Then, using a ruler, mark the side of your rain gauge! Place your rain gauge outside. You’ll need to pick a good spot! You want somewhere level, open to the sky, and not likely to get too windy. Make sure nothing is hanging over the gauge (like a tree or roof).

Observe:

If it rains or snows within 24 hours, check your gauge and see how high the water is! That’s how much rain has fallen in the last day! In your weather journal make a note of the day and amount of rain. Then go online and find the official rainfall amount…how closely did your amount match? Repeat whenever it rains!

Daily Discovery: Investigating Clouds

NASA scientists study clouds to better understand and predict how Earth’s climate is changing. Community members can collect data about clouds and share it with scientists to help do this important research. In this activity, you will record cloud observations and learn how you can share data with researchers who collaborate with NASA!

Supplies:

Pencil
Book, clipboard, notebook, or other hard surface to write on
Investigate Your Sky Today activity sheet, or a blank piece of paper

Instructions:

Investigate the sky! If you are able to, go outside or observe the sky from a window.
Notice and observe the shapes of the clouds you see. Are the clouds puffy with clear edges, thin and whipsy, or layered and sheet-like?
Then draw a detailed sketch of what you see. The sky is big. To make an accurate observation, it is helpful to orient yourself north, divide the sky into quadrants, and sketch what you see in each one. If there are no clouds today, that’s okay! That is real data too, so make a note.
Now, estimate the cloud coverage. How full is the sky today? Make an estimation how much the sky is covered with clouds from 0-100%.
When you are finished sketching, go inside. Write down the date and time of day that you make your observations. Write down observations about the shape, size, color, and any features you noticed about the clouds next to your drawings. Try to use some of the scientific vocabulary below to classify the clouds you observed!
If you enjoyed observing the clouds, join a community of participants working with NASA to collect important scientific data about clouds. Learn more and download an app to contribute your cloud observations: observer.glove.gov.

Descubrimiento en casa: Investigando las nubes

Los científicos de la NASA estudian las nubes para entender su función y también para predecir cómo está cambiando el clima. Pero, ¿sabías que tú también puedes colectar datos sobre ellas y compartirlos con los científicos? ¡Tus observaciones podrían resultar en investigaciones muy importantes! En esta actividad, vamos a observar a las nubes haciendo varias anotaciones mientras aprendemos cómo compartir estos datos ¡con los investigadores que colaboran con la NASA!

Artículos necesarios:

Página de actividad incluida “¡Investiga el cielo de hoy!” o papel blanco
Una superficie firme para escribir (como un libro, un portapapeles, o un cuaderno)
Algo para escribir (lápiz, pluma o marcador)

Instrucciones:

¡Investiga el cielo! Si puedes, ve afuera, o también puedes observar el cielo desde una ventana.
Presta atención a la forma de las nubes. ¿Son densas con bordes claros, delgadas y tenues, o tienen capas con áreas grises?
Ahora dibuja detalladamente lo que ves. ¡El cielo parece ser infinito! Para formar una observación precisa, es útil orientarse hacia el norte, dividir el cielo en cuadrantes (o cuatro partes), y dibujar lo que observas en cada uno de ellos. Si no hay ninguna nube, ¡no te preocupes! Apúntalo de igual manera porque este dato también provee información importante.
Estima su cobertura. ¿Qué tan lleno está el cielo de nubes? Haz un estimado desde 0-100%.
Cuando termines de anotar tus datos, apunta la fecha y hora en las cuales hiciste tus observaciones. Al lado de tus dibujos, escribe sobre sus formas, tamaño, color y otras características que hayas notado. Puedes tratar de utilizar el vocabulario científico incluido abajo para clasificarlas.
Si esta actividad te ha gustado, únete a la comunidad de participantes que trabajan con la NASA para recopilar datos científicos importantes sobre las nubes. Obtén más información y encuentra una aplicación para contribuir con tus observaciones en: observer.glove.gov.

Daily Discovery: 3-D Constellation

Posted on April 14, 2020February 18, 2021 by Kristin Rush in Ages 6-8, Ages 9-12, Crafts, Daily Discovery, Discovery at Home, Earth & Space Science

Post written by Sierra Tamkun, Learning Experiences Manager.

Daily Discovery: 3-D Constellation

Twinkle twinkle little star… I wonder how far away you are! From Earth, stars in constellations look like they grouped together in the same area of space. In reality, they are at different distances from us, and only look grouped together because of our perspective. Make your own 3-D constellation and see how close (and far away!) the different stars in the constellation Orion are to Earth!

Supplies:

Piece of cardboard or cardstock
Thin string or thread
8 small beads (pony beads work well!) or buttons
Tape
Orion constellation images (attached)
Needle or pushpin
Pen or pencil
Ruler

Instructions:

Draw out the constellation Orion on your piece of cardboard, or print the constellation provided and glue it on. Tip: if drawing the constellation, don’t forget to add the names of the stars!
Poke a hole through the cardboard where each star is located.
Cut 8 pieces of string. Each piece should be about 18 inches long.
Tie a bead onto the end of each piece of string. These will be your stars!
Thread the end without a bead through each of the holes on your cardboard.
Using your ruler and the chart below, pull your string through until the bead is the correct distance from the cardboard. This distance will be different for each star. Place a piece of tape over the back of the string to keep it in place at the right length!
Hold your constellation board above your head and allow the beads to hang towards you as you look up. From this perspective, the beads align to form the constellation Orion, just like on Earth!
Now hold the board in front of you, allowing the beads to hang towards the floor. From this different perspective, see how the stars are not on the same plane but all in different locations in 3D space!

Daily Discovery: Egg-cellent Egg-tivities – Part 2

Let’s learn all about eggs! What are eggs, anyway? What animals do they come from? What are the different parts made of? What can we do with eggs?

Glowing Egg

People who raise chicks use a technique called candling to determine if an egg is fertilized and has a chick growing inside of it. Your eggs from your refrigerator at home will not have a chick growing inside, but this is a really neat way to look inside an egg!

Supplies:

One egg
Flashlight
Dark room

Instructions:

Hold the egg gently in your hand (or ask an adult to help you) and press the flashlight carefully against the eggshell.
Carefully rotate the egg to see it from different angles.
What can you see? Do you see the spots in the egg shell? Do you see the air cell?
a. The egg shell is almost entirely composed of calcium carbonate. There are pores in the egg shell that allow some breathability to the shell.
b. The air cell forms when the egg is laid. You can see where the air cell was when you look at the flat end of a boiled egg.

Floating Egg

Learn about density and buoyancy through this floating egg experiment. Don’t forget to make your hypothesis about what will happen to each egg!

Supplies:

Two eggs
Water
Two tall drinking glasses
Three tablespoons of salt

Instructions:

Fill one glass ¾ of the way with water.
Make a hypothesis about what will happen to the first egg.
Carefully place the egg into the glass of water and observe. What happened to the egg?
Fill a second glass ¾ of the way with water.
Add 3 tablespoons of salt and stir.
Make a hypothesis about what will happen to the second egg.
Carefully place the second egg into the second glass of water and observe. What happened to the egg?

Tip: If an egg floats in water without adding salt, the egg is likely old. The air cell has grown inside the egg, making it buoyant. Check the egg for a bad smell before you eat it.

Egg Carton Art

Save that egg carton! It can be upcycled and turned into so many amazing things. You can cut it, glue it, build with it, paint it, use it to hold small loose things like beads or pretty rocks. There are endless possibilities!

This activity will show you how to cut apart an egg carton to make upcycled flowers. Share your egg carton creations with #dailydiscovery!

Supplies:

Egg carton(s)
Scissors
Glue, decorative paper, paint, paintbrush (optional)

Instructions:

Ask an adult to help you cut out the center pointy pieces of the egg carton. Be sure to leave plenty of the “petals” on them.
Use the scissors to cut out the petals of the flower. Try cutting them in different shapes!
Cut a long sturdy stem piece with a little tab on one end from a flat part of the egg carton.
Make a hole in the base of the flower and thread your stem through the hole with the tab resting inside the flower. That will keep the stem from sliding out of the flower. Optional: use glue to keep the stem in the flower.
Use paint (if you have some) to decorate your flowers. Be creative! You can also use paper to make leaves or more petals on the flower. Let the flowers dry and then pop them in a vase to bring cheer!

Natural Egg Dying: Cooking with Science!

Experiment with these natural dyes to make beautiful, colorful eggs that are totally edible! The best part is, you can make these dyes using items you have in your kitchen, and you don’t have to waste any food in the process.

Adult supervision is required for this activity.

Supplies:

Hard-boiled eggs
Saucepan
Water
White Vinegar
Clean kitchen or paper towels
Slotted spoon
Small bowls
Cheesecloth, fine sieve, or strain
Natural dying materials from your kitchen (Suggestions: beets, ground turmeric, coffee, spinach, yellow onion skins, red cabbage, yellow delicious apple peels)

Instructions:

Gather materials for your natural dyes. This is a great opportunity to reduce, reuse, and recycle! Try using your kitchen waste like yellow onion skins, any stale coffee, or apple peels for dyes! If you use fresh produce, like a beet or red cabbage, think about how you might eat the boiled vegetables afterwards.
Now comes the fun part! Experimenting with different natural materials can produce surprising colors, and don’t hold back from mixing 2 or more materials together to achieve new colors.
Prepare your natural materials into liquid dyes according to which materials you are using. Always use adult supervision when you are using the stove or chopping vegetables.
a. For the whole vegetables, like red cabbage or beets, chop them into smaller pieces first(around one inch). Place 1 cup of desired material in your saucepan and cover with 1 quart of water. Simmer the mixture for 30 minutes, or until desired color is achieved. Strain mixture and reserve the liquid.
b. For the spinach, onion skins, or apple peels, place about 2 cups of desired material in saucepan and cover with 1 quart of water. Simmer the mixture for 30 minutes, or until desired color is achieved. Strain the mixture and reserve the liquid.
c. For the ground turmeric, place 2 tablespoons of turmeric in 1 quart of water. Simmer the mixture for 30 minutes. Strains the mixture if you are using cheesecloth, otherwise, don’t worry about straining. Reserve the liquid.
d. If you are using stale coffee, there are no preparations needed. Skip ahead to the next step!
Place reserved liquids in individual small bowls. Stir in 2 tablespoons of white vinegar per every cup of liquid dye.
Retrieve your hard-boiled eggs when you are ready to dye. Make sure to keep them refrigerated at all times when you are not using them!
Use a slotted spoon to slowly lower your hard-boiled egg into desired color dye. Refrigerate the bowl to let the dye soak into the eggshell.
Time for the big reveal! After at least 30 minutes, use your slotted spoon to remove the egg from the dye.
Pat the egg dry using paper towels or a clean kitchen towel. To mix colors, you can soak an egg first in one colored dye for 30 minutes or more, followed by a second soak in another colored dye for 30 minutes to an hour. Get creative and experiment with different soak times and color mixtures to achieve a whole spectrum of colors!
a. Note that natural dyes will produce a subtler color than artificial dyes. For more vibrant natural colors, you can soak your eggs in the refrigerator overnight.
Store the colored eggs in an egg carton in the refrigerator until you are ready for an egg-celent snack.
