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:**

_Veronica

_Day

_Matt


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

We are doing the star Rigel.

**Materials we need**:
 * Masking tape - Veronica
 * Foam ball - me
 * Toothpicks- Veronica
 * Paint- me
 * Bamboo skewers- me
 * How are we going to scale this? What is our scale? Example 1 inch = 500 miles**

1 inch= 10 million miles

the diameter is about 68 million miles so the foam ball should be about 7 inches in diameter.


 * 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**

Hydrogen becomes Helium inside the core of a star. The pressure, gravity and heat inside of a stars makes this possible


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

A blue star is hotter because blue photons have more energy than red photons, which means it is generating more energy than the red star.


 * 3. What are the 6 types of stars? /6 pts**
 * 1) Main Sequence stars
 * 2) Red Giant
 * 3) White Dwarf
 * 4) Brown Dwarf
 * 5) Variable Stars
 * 6) Binary Stars


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

It helped because I thought stars were just balls of fire and didn't have anything like layers and stuff like that.


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

Yes. Some of us did research, some of us brought materials, some of us painted, and some of us worked on other things for it.


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

The core is one of the stars layers, and is located in the center of the star. The pressure in the core makes it possible for hydrogen to be fused into helium there, and that's important because it makes them hotter and brighter. The size of the core depends on the mass of the star. The density of the core is 150 times the density of water. The core is important to the star because releases all energy for the star, and a majority of the heat because of fusion. The star wouldn't exist without a core and fusion.
