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:

_Jennifer

_John

_Chandler

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

Materials we need:

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

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

Our scale is 1inch = 100,000 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 is nuclear fusion. In the core the protons can collide to cause helium protons which releases energy, this process is known as nuclear fusion.

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

A blue star is hotter because the color the star is based on the temperature and stars appear different colors.

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

The six types of stars are main sequence stars, red giant stars, white dwarfs, neutron stars, brown dwarf stars, and variable stars.

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

This project helped me understand a star better by helping me understand how the layers of a star work and learn about other stars in the universe.

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

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

The core of a star is where the star releases energy. In the core of a star there are protons. There in the core, the protons start moving around at a fast speed and combined with intense heat they collide causing nuclear fusion. The fusion creates helium particles which release the energy needed to supply the star's energy source. This is how the core releases energy.
