 * 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:
 * 1) Maria
 * 2) Chandler
 * 3) John

Our star that we chose is the __Alpha Centauri__
 * Star you want to model**: You will need to show the layers, so have a cross-section in your model.

Materials we need:

Maria - exacto knife, cutter board, and craft supplies John - paints and paint brushes Chandler - Styrofoam sphere Me - Glue, scissor, and foam brushes

How are we going to scale this? What is our scale? Example 1 inch = 500 miles

Every 1 inch is 100,000 kilometer

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 nuclear fusion happens inside a star. In the core, the protons join together with fast speed which forms helium nucleus. (http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question13.html)

2. Which is hotter a red star or a blue star? Why? _/4 pts
 * The blue star is hotter because the blue star's light has a higher frequency than the red star. The star turns blue when the tmeperature is 10,000 kelvins.( http://www.universetoday.com/24596/what-is-the-hottest-star/)

3. What are the 6 types of stars? /6 pts
 * The six types of stars are main sequence star, red giant, white drawf, brown drawf, variable star, and binary star. ( http://space.about.com/od/stars/tp/What-Are-The-Different-Types-Of-Stars.htm)

4. How did this project help you understand a star better? /4 pts
 * This project help me understand the star better by making a star to have a better visual of what is inside of it.

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

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

The radiative zone is a layer in the star where energy is transferred to a photon diffusion. The radiative zone is located near the innermost core. The radiative zone traffers energy resulting from the nuclear fusion. Then it is moved by the photon emission. Once the energy hits the radiative zone, it starts to move around the convection zone. The convection zone carries out heat and energy. This is how the radiation zone works inside of the star. (http://www.windows2universe.org/sun/Solar_interior/Sun_layers/radiative_zone.html)
