Problem: I would like you to work in groups of 4 and create a scale model of a star. Using technology to do some research about a star of your choosing and knowing what we know about scaling, you are going to build a model of the star with materials of your choosing. The materials you need to build this star are to be brought into class, and you will have 3-4 full class periods to assemble your star as a group. This will count as a summative assessment for Science for this unit. After the assembly of the stars you will need to show answer a few review questions on your own to receive full credit.

Lab Partners:

-sara

-maggie

-molly

Star you want to model: You will need to show the layers, so have a cross-section in your model. We modeled the star, Eta Carniae https://www.nasa.gov/content/goddard/nasa-observatories-take-an-unprecedented-look-into-superstar-eta-carinae

Materials we need: -sponge -red, purple, blue, yellow paint -scissors -bag

How are we going to scale this? What is our scale? Example 1 inch = 500 miles Our scale is 1 centimeter = 45 milliom miles.

Review Questions: Please answer the following and place them on your wiki. Make sure to include the question also./20 pts

1. What type of nuclear reaction happens inside a star? What processes of creating a star make this possible? _/4pts Stars are powered by nuclear fusion in their cores, this is made possible by the fusion of the gasses in the stars' creation. The power and energy from the core causes this reaction to happen.

2. Which is hotter a red star or a blue star? Why? _/4 pts

A blue star is hotter than the red star because there is more hotter gas and more energy through the stars. Also the frequency between the red light is less than the temperature of the blue star. Therefore the blue star is hotter.

3. What are the 6 types of stars? /6 pts The six types of stars

A white dwarf is a small, very dense, hot star that is made mostly of carbon. These faint stars are what remains after a red giant star loses its outer layers. Their nuclear cores are depleted. They are about the size of the Earth (but tremendously heavier)! They will eventually lose their heat and become a cold, dark black dwarf. Our sun will someday turn into a white dwarf and then a black dwarf.
 * WHITE DWARF**

A brown dwarf is a "star" whose mass is too small to have nuclear fusion occur at its core (the temperature and pressure at its core are insufficient for fusion). A brown dwarf is not very luminous. It is usually regarded as having a mass between 1028 kg and 84 x 1028.
 * BROWN DWARF**

A neutron star is a very small, super-dense star which is composed mostly of tightly-packed neutrons. It has a thin atmosphere of hydrogen. It has a diameter of about 5-10 miles (5-16 km) and a density of roughly 10 15 gm/cm3.
 * NEUTRON STAR**

A pulsar is a rapidly spinning neutron star that emits energy in pulses.
 * PULSAR**


 * RED GIANT** red giant is a relatively old star whose diameter is about 100 times bigger than it was originally, and had become cooler (the surface temperature is under 6,500 K). They are frequently orange in color.


 * BLUE GIANT** blue giant is a huge, very hot, blue star. It is a post-main sequence star that burns helium.


 * SUPERGIANT**

A supergiant is the largest known type of star; some are almost as large as our entire solar system.. These stars are rare. When supergiants die they supernova and become black hole.

4. How did this project help you understand a star better? /4 pts

5. Did everyone work together equally on this project? ___/2 pts Do not use any names in your answer on the wiki

Yes we worked very productively and had a fun time.

Write a description in your own words describing how one layer of a star works

The convective zone of the star is located near the middle of the star. It is above the Tacholine layer. A region of turbulent plasma between a star's core and its visible photosphere at the surface, through which energy is transferred by convection. In the convection zone, the heated plasma rises, cools as it nears the surface, and falls to be heated and rises again. If you were to dissect the star, it is right underneath the photosphere. the purpose of this layer is to have the hot and cold air travel through the star. The air circulates through the star which causes a convection zone. The convective zone of the star is important because it circulates and transfers the air through the star which makes the stat have the correct temperature. The convective zone is supported by the radiative zone. There is solar mass contained with plasma that cools And heats and rises and falls.
