 * 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:

_ Alex

_ Maria

_ Ethan


 * Star you want to model**: You will need to show the layers, so have a cross-section in your model.

Materials we need:
 * Super glue
 * poster board
 * 2 blocks of Styrofoam
 * paint( orange, yellow, and red)
 * Exacto knife

How are we going to scale this? What is our scale? Example 1 inch = 500 miles Ratio of the sun 57,983 km. for every inch. 12 inches = 695,800 km

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

1. What type of nuclear reaction happens inside a star? What processes of creating a star make this possible? ___/4pts__

The type of nuclear reaction that happens inside a star is nuclear fusion. Nuclear fusion is powered inside the cores, mostly converting hydrogen into helium. This happens when two protons collide and actually fuse together. Protons actually reflect each other so you can only imagine the speeds the have to be going to not only hit each other but fuse together to create a whole new element. The process is heat and pressure go up and the more pressure the hotter it is.

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

A blue star is hotter than a read star. It is hotter because the color blue emits a higher frequency of radiation than red. The wave length in blue is smaller than a red length. On the electromagnetic spectrum the color blue has more energy. Heat is a form of energy so when a star has more energy it has more heat. Therefore a blue star is hotter than a red star.

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


 * 1) Main sequence star
 * 2) Red giant star
 * 3) White dwarf
 * 4) Neutron stars
 * 5) Variable star
 * 6) Brown dwarf

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

This project helped me understand my star more because I got a real life example of it's color, shape, and layers inside.

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

Yes, everyone worked equally on this project. Some people painted, looked up information, one person put it on the wiki, some labled it, and others cleaned up.

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

The core is the hottest part of the sun and the solar system. It has a temperature of 15 million degrees Celsius. It creates heat by burning cases, which keeps the earth warm. It's made of hot, dense gases in ions and electrons. The core inside 0.20 of the solar radius, contains 34% of the suns mass, and 0.8% of the suns volume. There are two distinct reasons in which four hydrogen nuclei may eventually result into one helium nucleus. The two reasons are proton chain reaction, which is responsible for most of the suns released energy, and the CNO cycle. The core is the hottest part of the sun and plays a big part in the process in the sun.
