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:

_ Natalie

_ Maria

_Ethan

Star you want to model: You will need to show the layers, so have a cross-section in your model.
 * The sun
 * Materials we need:
 * Styrofoam
 * Red, orange, and yellow paint
 * Exacto Knife

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

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
 * The type of nuclear reaction that happens in a star is nuclear fusion. Heat and pressure create nuclear fusion. Two protons traveling at incredible speeds actually collide and they fuse together to create a hydrogen atom. Hydrogen atoms have two protons helium has one. Protons actually reflect each other like if you try to put two north or south poles of a magnet. Imagine that but by a lot more so you can only imagine the speeds two protons have to be going to not only collide but fuse together to create a whole new element.

2. Which is hotter a red star or a blue star? Why? _/4 pts
 * A blue star is hotter than a red star. It is hotter because the color blue emits a higher frequency of radiation then red. The wave length in blue is smaller than a red wave length. Also on the electromagnetic spectrum blue has more energy than red. Heat is a form of energy, since blue has more energy it is contains more heat.

3. What are the 6 types of stars? /6 pts The six types of stars are
 * 1) Main sequence star
 * 2) Red giant star
 * 3) White dwarfs
 * 4) Neutron stars
 * 5) Variable star
 * 6) Brown dwarfs

4. How did this project help you understand a star better? /4 pts It helped me understand the star better by giving me a to scale model of what a star is.Also actually being able to inspect the layers of it in a 3D scale and being able to actually understand how the layers work and how big they are compared to the other layers.

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 of us painted and some of us helped with the questions and everyone did a good job bringing in the supplies that they needed to bring in.

Write a description in your own words describing how one layer of a star works
 * The core is the first layer of the sun, and it takes a lot for it to work. The core of the Sun is considered to extend from the center to about 0.2 to 0.25 solar radius. It is the hottest part of the Sun and of the Solar System. It has a density of 150 g/cm³ (150 times the density of liquid water) at the center, and a temperature of 15 million degrees Celsius. It creates heat by burning gases which then heats our Earth.This process is called nuclear fusion. This fusion changes a very small part of the hydrogen atoms into a large amount of energy. This energy then travels from the core to the surface of the Sun. The Sun's surface is called the photosphere and is where it shines the energy into space. The core is the hottest layer of the sun and plays a big role in the sun.
