Daily Discovery: Life Cycle of a Star Mobile

One star, two star, red star, white dwarf star! Throughout it’s billion-year life, a low-density star, just like our Sun, goes through many changes. Learn about the different stages in a star’s life cycle, and make your own star mobile!

The Life of a Star

A star’s life cycle is determined by how big it is, or how much mass it has! The greater the mass of the star, the shorter its life. Depending on the amount of matter in the nebula where the star is born, it will either be a high-mass star, or a low-mass star, like our Sun. We’ll use this life cycle for our mobile.

But how are stars formed, anyway? As clouds of gas and dust move around in a nebula, hydrogen gas is pulled together by gravity and begins to spin faster and faster, heating up to become a protostar. When hot enough (about 15,000,000 degrees Fahrenheit!), a reaction called nuclear fusion occurs at the star’s core, pulling in more gas and dust and causing the star to stabilize and glow bright! It will continue shining in this phase as a main sequence star for millions to billions of years. Our closest star, the Sun, is currently at this stage.

Over time, hydrogen at the star’s core is converted to helium through nuclear fusion. Once the hydrogen runs out, the star isn’t able to generate enough heat to maintain its size. The core contracts, while the outer shell expands and cools, glowing red. This is known as the red giant phase. As the core continues to cool, the helium begins to fuse into carbon. Once all the helium is gone, the core collapses, and the outer layer is expelled into gases and dust, creating a planetary nebula! The collapsed core remains as a white dwarf, slowly cooling to become a black dwarf.

A high-mass star undergoes a supernova explosion after its red giant phase. If the explosion is small, it become a neutron star. But if the explosion is large, the core of the star is swallowed by its own gravity, becoming a black hole!

Supplies:

  • Paper Plate
  • Colorful beads, pom-poms, sequins, colored paper, cotton balls, pillow stuffing, etc.
  • Paints, markers, or crayons
  • Scissors
  • Glue
  • String

Instructions:

  1. Decorate your paper plate like outer space! This will be the backdrop for your star’s life cycle.
  2. Carefully use the scissors to cut your paper plate into a spiral. Ask an adult to help you if needed! Leave a small circle at the center of your spiraled plate.
  3. At the top of your spiral, attach your sting so you can hang your mobile when you’re done! You can use glue or tape, or poke a hole through the plate and tie your string to attached it.
  4. Select different objects to represent each stage in the life of your star. Pick any materials you like, or follow these suggestions:
    a. Star-forming nebula: cotton balls or pillow stuffing
    b. Protostar: small light-colored bead or sequin
    c. Main Sequence Star (like our Sun): yellow bead or pom-pom
    d. Red Giant: large red pom-pom or red paper circle
    e. Planetary Nebula: small bead and cotton balls or pillow stuffing
    f. White Dwarf: white bead or pom-pom
    g. Black Dwarf: small black bead or pom-pom
  5. Start by gluing your nebula materials at the very top of your spiral plate, around the string. Next, glue your black dwarf to the end. Evenly space out the rest of your representative objects and glue them to your spiral plate in the appropriate order.
  6. Use the string to hang up your mobile! As it spins, follow along with the different life stages of a star just like our very own Sun!

Descubrimiento en casa: Móvil del ciclo vital de una estrella

Durante los billones de años que podría durar su existencia, una estrella de densidad baja (al igual que nuestro Sol), experimenta muchos cambios. Aprende más sobre las diferentes etapas de la existencia de una estrella, y crea tu propio móvil.

El ciclo de vida de una estrella

El ciclo de vida de una estrella se determina por su tamaño o por su masa. Mientras más contenido tenga de esta, más corta resulta su vida. La cantidad de sustancia retenida por una nebulosa determina si va a nacer una estrella de masa alta o baja, como el Sol. Vamos a representar estas etapas de vida en nuestro móvil.

Pero, ¿y cómo se forman las estrellas? Mientras nubes de gas y polvo trastean en una nebulosa, hidrógeno molecular empieza a unirse por la fuerza de la gravedad. Girando más rápido, el hidrógeno se calienta y se vuelve una protoestrella. Cuando está suficientemente caliente, (¡8,333,315 grados Celsius, o 15,000,000 grados Fahrenheit!), comienza una reacción llamada fusión nuclear en el centro, atrayendo más gas y  polvo. En un corto tiempo, la estrella se estabilizará y emitirá un resplandor brillante. Esta continuará a emitir su luz por millones o hasta por billones de años. La estrella más cerca de la Tierra, el Sol, está actualmente viviendo esta etapa.

Cuando pasa el tiempo, el hidrógeno presente en el centro de la estrella se convertirá en helio a través de la fusión nuclear. Cuando el hidrógeno se haya agotado, la estrella no tendrá la capacidad de conservar la temperatura que necesita para mantener su tamaño. El centro de la estrella se contractará mientras que su capa exterior se expandirá y enfriará, brillando en un color rojo. Esta etapa de su vida se llama “la gigante roja.” Mientras se enfría el centro de la estrella, el helio se convierte en carbón. Cuando se extingue el helio, el centro se derrumba y su capa exterior expulsa gases y polvo, formando una nebulosa. El centro de la estrella sigue desprendiendo capas y enfriándose, existiendo como una “enana blanca.” Eventualmente se convertirá en una “enana negra.”

Una estrella de masa alta experimenta una explosión supernova después de ser una gigante roja. Si la explosión es pequeña, la estrella colapsa a un tamaño compacto, una “estrella neutrónica.” Si la explosión es grande, la gravedad puede comerse el centro de la estrella y convertirse en un “agujero negro.” Después de esta información tan interesante, ¿estamos listos para nuestra actividad?

Artículos necesarios:

  • Plato desechable de papel
  • Abalorios, cuentas o chaquiras, pompones, lentejuelas, papel de varios colores, bolas de algodón, relleno de almohada, etc.
  • Pinturas, marcadores y lápices de colores
  • Tijeras
  • Pegamento
  • Cordel/cuerda/hilo

Instrucciones:

  1. Decora tu plato de papel como el espacio. Este será el telón de fondo para el ciclo de vida de tu estrella.
  2. Con cuidado, usa las tijeras para cortar tu plato de papel como un espiral. Si es necesario, pídele ayuda a un adulto, dejando un centro redondo y bien pronunciado.
  3. Usa pegamento, cinta adhesiva, o haz un agujero en el centro del plato para atar un cordel.
  4. Selecciona varios objetos para representar las diferentes etapas de la vida de tu estrella. Escoge los materiales que prefieres o que tengas disponibles. Si quieres, sigue estas sugerencias:
    a. Nebulosa de vivero estelar: bolas de algodón o relleno de almohada
    b. Protoestrella: chaquira o lentejuela pequeña y de color claro
    c. Estrella de secuencia principal (como el Sol): abalorio o pompón amarillo
    d. La gigante roja: pompón grande o recorte de círculo de color rojo
    e. Nebulosa planetaria: bola de algodón, abalorio pequeño, o relleno de almohada
    f. Enana blanca: abalorio o pompón blanco
    g. Enana negra: abalorio o pompón negro pequeño
    Pega los materiales a tu espiral empezando de arriba hacia abajo y en orden. Asegúrate que estén uniformes y bien espaciados.
  5. Cuando termines de armar tu móvil, cuélgalo. Mientras gira, ¡observa las diferentes etapas de la vida de una estrella!

Daily Discovery: Bending Light and Eyesight

Post written by Angela Kettle, School Programs Coordinator.

Daily Discovery: Bending Light and Eyesight

Have you ever noticed that your legs look out of place when you dangle them in the pool, or that the straw in a glass of water looks bent? This is called refraction. Refraction occurs when light bends as it passes from one medium to another – for example, from the front of a glass, to the water inside, to the back of a glass. Experiment with refraction for yourself in the activity below!

Supplies:

  • Paper
  • Pencil
  • Crayons, colored pencils, or markers (optional)
  • 2+ different kinds of drinking glasses, filled with water – make sure the glasses are transparent
  • Your Observation Journal (find out how to make one here), or use another sheet of paper to record your findings

Instructions:

Part 1

  1. Draw an arrow on a sheet of paper. Note which way the arrow is facing (right, left, up, or down).
  2. Fill up a glass of water.
  3. Put your glass of water down, and put yourself at eye level with the water in the glass. Hold your drawing at arm’s length, so that you can see it through the glass. What do you notice about the way your drawing looks now? What about if you look at the image through the glass from a different angle?
  4. Repeat the experiment, this time with a different kind of glass. Does the image stay the same as the last glass, or does it change?
  5. Write or draw your findings in your Observation Journal.

Part 2

  1. Draw something new – whatever you like! Make sure that whatever you draw has certain parts facing one way or another (for example, you could draw a face with the eyes looking left, or a cat with its tail on the right side of the paper and its head on the left side).
  2. Look at your drawing through your glass of water, like you did with the arrows. What do you notice?
  3. Play around with your drawing and your glass. Try looking at the image from lots of different angles, through as many different kinds of drinking glasses as you can. How many different images can you create from your original image, just by experimenting with refraction?
  4. Record your findings in your Observation Journal. Share what you find by tagging us on social media and using #DailyDiscovery.

From Drinking Glasses to Eyeglasses

Refraction might seem like a fun magic trick, but did you know that refraction is what makes it possible for humans to see? Light is refracted as it passes through the cornea and the lens of the eye. This allows the light to come into focus on the retina, where it is converted into a message that the brain can understand.

Sometimes, though, refraction can go wrong, causing what’s called nearsightedness or farsightedness. When people are nearsighted, it means they can see things that are close to them, but not far away. Usually, this is caused by the eye being too long, causing light to focus in front of the retina. When people are farsighted, it means they can see things that are far away, but not things that are close. Usually, this is caused by the eye being too short, causing light to focus behind the retina. Both nearsightedness and farsightedness can also be caused by problems with the shape of the eye’s lens.

Thankfully, errors in refraction can be corrected with eyeglasses. First, an eye doctor (an optometrist) tests a patient’s vision to figure out her prescription (a way of measuring a person’s vision). From there, an engineer uses this prescription to make unique lenses. This lens is engineered to refract light so that it focuses in just the right spot on the retina, allowing the patient to see clearly.

Eyeglasses through the Ages

Eyeglasses have undergone many changes as engineers have figured out more efficient ways to craft them… and as fashion has changed, too! Here are a few historical photos from our Archive and a piece from our Collection at the museum! You can learn more about eyeglasses and fashion from our recent blog post, parts of which are adapted below:

The museum’s artifact collections offer a retrospective look (which is 20/20, of course) at the history of innovation in eyewear. Pince-nez spectacles, which had no earpieces and stayed in place with a nose clip were quite popular early in the 20th century but fell out of fashion as they became associated with older generations.

Fort Collins & The Flu: 1918-1919

Post written by Sarah Frahm, Archive Assistant.

Fort Collins & The Flu: 1918-1919

What did Fort Collins look like the last time the city faced a widespread shutdown? From the fall of 1918 through the early spring of 1919 the citizens of Fort Collins found themselves under varying stages of quarantine due to the influenza epidemic. One document, currently at the Archive, that gives some insight into how the city officials handled the epidemic and quarantining of the population is a “Summary of Advisory Committee Recommendations.”

Fort Collins Quarantine Recommendations

Most telling about the problems the city faced in managing the flu epidemic is that the advisory committee was not even formed until December 1918, despite influenza raging in the city since at least October. According to an October 18th article in The Weekly Courier the state board of health had ordered the closing of “everything” in Colorado  but that those in charge of the college campus, where men were still doing military training, would not close the campus. The previous week an editorial had appeared in the newspaper demanding a “rigid quarantine be established” and that the city should be “shut down tight” like Boulder and Greeley. By the end of the October both the college and the city had enacted some form of closure, although without official documents it is a challenge to tell just how strenuous the shutdown was. Another article mid-November from The Weekly Courier complains that “quarantine has not been very rigid of late” with November seeing both elections and the armistice ending World War One and that these events and gatherings led to a rising in the number of flu cases.

 

The convening of a citizen advisory committee to the city board of health seems to be a recognition that the previous handling of the flu epidemic had been somewhat ad hoc and unclear (the November issues of The Weekly Courier discuss whether masks should be worn, or not, and if quarantine would be lifted, or not) and in need of some sort of codification.

But how did these regulations, once adopted, affect the citizens of Fort Collins? The first two points recommended by the advisory committee were not all that different from the quarantining, done before and after the influenza epidemic, for other diseases, like measles or scarlet fever. However, the third recommendation of shutting down schools and “ordinary public gatherings” was different. Social and fraternal clubs closed, such as the Elks (in April 1919, The Fort Collins Courier reports that the lodge was in remarkable good financial health despite having been closed for nearly three months. The women’s gymnasium, on the other hand, found itself struggling to have enough members in March.) The superintendent of the school district reported in the summer of 1919 that the school year had been full of “anxiety, hindrance, and depression” and that many of the plans for academic work had to be abandoned.

 The Elks Lodge was located at 202 Linden Street and was closed during the influenza quarantine.

If the lack of proper schooling and a severe curtail on social life were not bad enough, the fourth recommendation from the advisory committee was an extreme frustration to many in Fort Collins. Shortly after the requirement limiting the number of people in any place of business came out The Weekly Courier wrote an editorial telling people to quit complaining, pointing out that they too had to deal with these restrictions upon their office (if someone was to visit the newspaper office, a member of staff would have to leave in order to maintain the proper number of people per square footage). The editorial admonished the people the writer considered to be “knockers” to take the disease more seriously for the sake of the survival of the city.

While the committee was extremely serious on the subject of loafing on the streets (how else does a recommendation get to be written not only in capital letters but also underlined and starred?) the record of impact on peoples’ lives of that specific order is currently unknown. Rather it is the suborder that bares out most in the historical record. The committee called for a special officer to be appointed. The man who became “Quarantine Officer” was Orrin J. Watrous, then the secretary of the Fort Collins Commercial Club. According to The Fort Collins Express writing about the official vote of thanks put forth by the city government to Watrous, Mr. Watrous daily visited between “a dozen to twenty houses in his quarantine rounds” in order to ensure people were properly following the orders of the city.

Orrin Watrous, pictured here at the far right with a cigar in his mouth and boxing gloves on his hands.

When people did not follow quarantine regulations, there were consequences. One farmer, a Mr. Tom Hale, accused of breaking the quarantine on his house, had to go to court on December 27th and face trial. The Weekly Courier reported that Mr. Hale’s case was dismissed. While it is not clear what kind of fine or other penalty Mr. Hale would have had if he had been found guilty, his case is still an example of the added difficulties of living life under quarantine.

It is difficult to know, exactly, how people felt about the restrictions placed upon them by the city government. Currently there is only access to a weekly newspaper (even though the newspaper also ran dailies, Archive staff cannot get to them right now) and while there are potentially useful items held in the Archive collection, with our own doors closed, a lot of the details will have to remain unknown for the current time.

Daily Discovery: Baking with History – Fort Collins Brownies/ Descubrimiento en casa: Recetas con historia – bizcochos de chocolate (brownies) de Fort Collins

Post written by Charlotte Conway, Public Programs Coordinator.

Daily Discovery: Baking with History – Fort Collins Brownies

Have you ever had trouble getting a brownie recipe to rise? High altitude baking requires special adjustments to get the same results as lower altitudes. Lucky for us, people from FoCo history have already developed recipes perfect for baking in our Colorado high altitude.

Learn about Dr. Inga Allison, a figure from Fort Collins history, who developed the science for high altitude baking, and then grab a parent to help you bake through history!

Dr. Inga Allison’s High Altitude Brownies Recipe

Inga Allison joined the Home Economics Department at Fort Collins’ Colorado Agriculture College from 1903 to 1908, at a time when several faculty members were starting to study the unique effects of high altitude on both crop growth and food preparation. Lacking an established lab, Allison conducted her experiments in cooking at altitude with improvised equipment in challenging conditions – baking, for example, in a rough Estes Park shanty located at 11,800 feet above sea level!

You can thank Dr. Allison for most brownie recipes that work here in Fort Collins – they most likely take into account the science developed by Dr. Allison! Follow along with her original brownie recipe on the next page!

Descubrimiento en casa: Recetas con historia – bizochos de chocolate (brownies) de Fort Collins

¿Alguna vez has tenido algún problema siguiendo recetas de brownies? En Colorado -y en lugares con gran altitud- el hornear ciertos platillos requiere ajustes especiales para obtener los mismos resultados que en lugares con altitudes más bajas. Pero por suerte, existen recetas locales comprobadas que sirven para hornear con éxito en nuestra área.

Conoce a la Dra. Inga Allison; una figura histórica de nuestra ciudad que descubrió la ciencia para hornear en elevaciones altas. Con la ayuda de un adulto, usa esta receta histórica ajustada por ella para hacer unos brownies, ¡y comparte el delicioso resultado con tu familia!

Horneando pasteles con diferentes alturas.

Columna A – Pasteles horneados al nivel del mar sin ningún ajustamiento.

Columna B – Pasteles horneados al nivel del mar con ajustamiento de levadura en polvo.

Columna C – Pasteles horneados con recetas correctamente balanceadas para elevaciones altas.

Un archivo de la colección del museo que representa el experimento de una misma receta horneada a diferentes niveles de altura. A 3,048 metros (10,000 pies), a 1,524 metros (5,000 pies), y al nivel del mar. Observa cómo cambia la estructura de cada postre.

Receta de brownies ajustada por la Dra. Inga Allison

Inga Allison se unió al Departamento de Economía Doméstica en el Colegio Universitario de Agricultura de Fort Collins de 1903 a 1908. En aquel entonces, muchos miembros de la facultad empezaron a estudiar los efectos de la altura en el crecimiento de los cultivos y la preparación de alimentos. El colegio no tenía un laboratorio disponible, por tanto, Allison comenzó sus experimentos sobre la cocción en elevaciones altas con equipos improvisados y bajo condiciones difíciles; por ejemplo, horneaba en una cabina desgastada localizada en el pueblo de Estes Park, que está a unos 3,596 metros (aproximadamente 11,800 pies) de altura.

Podemos agradecerle a la Dra. Allison por desarrollar la ciencia que influye en la mayoría de las recetas de brownies creadas aquí en Fort Collins. ¡Sigue su receta original traducida en la página siguiente!

Receta para hacer bizcochos de chocolate (brownies) de Fort Collins:

Ingredientes:

  •  2/3 taza de harina de trigo
  • 1/2 cucharadita de levadura en polvo
  • 1/4 cucharadita de sal
  • 1/3 taza de manteca vegetal
  • 2 barras de chocolate sin azúcar
  • 1 taza de azúcar blanca
  • 2 huevos batidos
  • 1/2 taza de nueces
  • 1 cucharadita de vainilla
  • Para alturas de 2,286 metros (aproximadamente 7,500 pies) o de 3,048 metros (10,000 pies) sobre el nivel del mar, añade 1/4 cucharadita de levadura en polvo

Instrucciones:

Derrite la manteca vegetal junto con el chocolate a baño maría. En otro recipiente, agrega gradualmente el azúcar a los huevos batidos hasta que estén completamente mezclados. Agrégales la mezcla de chocolate y bate. Adjunta todos los ingredientes secos y mézclalos hasta que estén incorporados. Incluye las nueces y la vainilla. Coloca la mezcla en un refractario engrasado tamaño 20x20x5 centímetros (8x8x2 pulgadas) y hornea por 35 minutos a 180ºC (350ºF). Cuando esté todavía caliente, corta en forma de cuadros. Retíralos del recipiente y déjalos enfriar. Rinde para 2 docenas de brownies.

Daily Discovery: What’s Up With Yeast?

Post written by Heidi Furhman, Discovery Camp Coordinator.

Daily Discovery: What’s Up With Yeast?

What is yeast? How does it work? Why is it important for making the breads and treats we all love? Learn about yeast through our video “What’s Up With Yeast” and conduct this experiment to observe yeast at work for yourself!

Supplies:

  • Clear Bottle (water bottles work well)
  • Warm water
  • Package of Yeast
  • Sugar
  • Balloon

What is Yeast?

Check out our video “What’s Up With Yeast?” to discover the connection between bread and balloons, and explore what yeast is, how it works in bread dough, and what kinds of yeast people have been using for hundreds of years.

As you watch, conduct this experiment along with our educator Heidi!

Instructions:

  1. Gather your supplies! You’ll need a clear bottle, a balloon, warm water, sugar, and a package of yeast.
  2. Stretch out your balloon. Try blowing it up a couple of times to loosen it up.
  3. Add one to two inches of warm water to a clear bottle. Make sure the water is warm to the touch but not hot! If your water is too hot you’ll kill the yeast. A good test is to hold your wrist under the running water. If you can’t stand it the water is too hot! Which purposes does the warm water serve to help the yeast thrive? (Moisture and warmth).
  4. Add the package of yeast to the bottle. It will work if you use less than the whole package just adjust the sugar in ratio. (Note: A smaller amount of yeast will take longer to blow up the balloon). Mix up the water and yeast.
  5. Add about 1 Tablespoon of sugar to the yeast and water mixture and stir it around (or about equal parts yeast and sugar). What purpose does the sugar serve to help the yeast thrive? (Food).
  6.  Stretch the balloon over the top of the opening and set in a warm place for about 15-20 minutes.
  7. Observe what happened? What do you notice about the yeast mixture? Does it look different than when you put it in? What about the balloon has it expanded? What does that tell you about the yeast? What is causing the balloon to expand (carbon dioxide released by the yeast is filling the balloon!)
  8. You can leave your experiment alone for several hours or days and keep observing! Does your balloon keep expanding? What about the yeast? What happens to it? At some point the yeast will consume all the food and stop releasing carbon dioxide. Your balloon will likely deflate.
  9. You can try the experiment again! Try adding more yeast and sugar or less yeast and sugar. How does that impact the time it takes for the balloon to inflate? Try using hot water or cold water. What happens then? Is your yeast able to grow? If yes, does it grow faster or slower? If no, why do you think your yeast was unable to grow? (Packaged yeast needs warm water to reactivate since it’s suspended in a forced hibernation state. Too cold, and your yeast will not be reactivated, too hot and you’ll kill it!

Sourdough Starters

You can try making your own sourdough starter at home to observe living yeast! Remember it can take some practice and a whole lot of patience to get it right, but just about anyone can do it! If it doesn’t work the first time try again!

You’ll need flour, water, and a glass jar to get started.

Try this to get you started or google “Sourdough Starter” for many amazing resources and recipes to get you started.

Daily Discovery: Solar System String Model

Daily Discovery: Solar System String Model

How big is our solar system? Really, REALLY big! Astronomers use a unit of measurement called an Astronomical Unit, or AU, to calculate the distances of different planets from the sun and measure the size of our solar system. One AU is equal to the distance from the sun to Earth, about 93 million miles (150 million kilometers)! Use the chart in the linked PDF of relative distances provided to build your very own to-scale model of our solar system and planets!

Supplies:

  • Measuring tape with centimeter markings
  • 4.5-meter-long piece of string
  • Large craft pony beads (or other craft beads) in various colors
  • Small piece of cardboard or wood to wrap solar system string around

Instructions:

  1. Pick out different beads to represent each planet and the sun! Look for beads that are roughly the same colors – blue for Earth, red for Mars, green for Uranus, etc.
  2. Tie the bead representing your sun to the end of your string.
  3. Using the distances (in centimeters) in the chart below, measure the distance from the sun to the first planet, Mercury.
  4. Tie Mercury in place on your sting. Tip: ask an adult to help you to make sure it stays in place!
  5. Repeat steps 3 and 4 for each planet.
  6. Lay your sting out on the floor to see the relative distance between all the planets in our solar system!

On your solar system string, all the planets are in a line so we can see the distances between them, but in space, the planets all orbit around the sun. Want to see your string of planets in orbiting action? Have a friend or family member hold the sun, while you stand apart from them holding the end. With the string pulled tight, walk counter-clockwise around your friend to see how the planets circle the sun in outer space!

Post written by Lea Mikkelsen, Early Childhood Coordinator.

Daily Discovery: Recycled Bird Feeder

Are you enjoying watching the birds from your window at home? Take a look in your recycling and imagine what you can re-use to make a bird feeder. An oatmeal container? A plastic bottle? How about a milk carton? Let’s practice upcycling and turn that container into a beautiful bird feeder to hang in your yard!

Supplies:

  • A medium to large container from your recycling
  • Materials to decorate with. Try colored paper, stickers, bright colored or patterned tape, paint, tissue paper, leaves and  ticks, or other recycled materials.
  • A stick, dowel, or other similar item for the birds to perch on.
  • Scissors
  • String or a pipe cleaner
  • You might need tape or glue
  • Birdseed

Instructions:

  1. Place all your supplies on a clear surface with plenty of room to create.
  2. Brainstorm some ideas for what your birdfeeder could look like. Tip: try drawing your idea out on a piece of paper first.
  3. Ask an adult to help you cut a few doors into your container, a hole for the stick for the bird to sit on, and a place for the string to loop through to hang the feeder.
  4. Decorate your birdfeeder using your amazing creativity!
  5. Fill the birdfeeder with seed and hang it outside to watch from your window!
