 * 1) Create a wiki page called StarModel codeinitials.
 * 2) Copy the information below and paste it on your StarModel page.
 * 3) Enter the first name only of your lab partners.
 * 4) View **Web Search Strategies video**
 * 5) Work as a group to research information about stars. Find at least 4 scientifically valid sources of information about stars. Enter the URL for each of the resources used under each appropriate question.
 * 6) Use EasyBib to create a Works Cited list in MLA format with annotation for each entry.

 * 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: _ _

 * 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 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 Blue star is hotter than a red star. It is hotter because the color blue has a higher frequency of radiation then red. The wave length in blue is smaller than a red wave length. On the electromagnetic spectrum blue has more energy than red. Heat is form of energy, since blue has more energy, it contains more energy.

3. What are the 6 types of stars? /6 pts
 * Main sequence star
 * Red giant
 * White dwarf
 * Brown dwarf
 * Variable star
 * Binary star

4. How did this project help you understand a star better? /4 pts This project helped me understand the star better by seeing how it would be shaped and its color.

5. Did everyone work together equally on this project? ___/2 pts Do not use any names in your answer on the wiki -Yes, everyone wirked equally on this project. 3 of us painted and 1 of us helped with the questions. 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 radiative zone is a layer of a star's inner layer where energy is primarily transported toward the outer by means of radiative diffusion, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as photons. Inside the Sun, the radiation zone is located in the intermediate zone between the solar core at .2 of the Sun's radius and the outer convection at .71 of the Sun's radius.The radiative zone is mainly where all the energy is moved to the outside and it spreads.
