 * 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:

_ Paola

_Jenna

_Mia

_ Nick


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

Materials we need:
 * Nick - styrophone circle
 * Paola -paint: blue, white, white glitter
 * Jenna - paint brushes and scissors
 * Mia- paint containers

Bellatrix
 * Name of Star:**

https://en.wikipedia.org/wiki/Bellatrix
 * Notes:**
 * Bellatrix is the third brightest star in the Constellation Onion.

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

Diameter of Bellatrix: 8.4 Million KM 12 inch ball 100000= 1 inch

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 inside a star is nuclear fusion. The processes of making a star is gravity because it causes pressure which is colliding and it makes heat.

2. Which is hotter a red star or a blue star? Why? _/4 pts A blue star is hotter because the gravity and the pressure colliding which makes heat and because on the heat scale it shows it.

3. What are the 6 types of stars? /6 pts The six types of stars are:
 * Main Sequence stars
 * Red Giant Stars
 * White Dwarf.
 * Neutron Stars
 * Black Holes
 * Brown Dwarfs.

4. How did this project help you understand a star better? /4 pts This project helped me understand a star better by finding out more on how a star forms and how the get hotter with gravity and the pressure which forms heat.

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 and when we needed help, we were all helpful. The communication was a success, everybody worked on what we were assigned because on looking up different information and then when we were done we gathered all of our information into one.

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

The layer called the core is the hottest layer of all layers in a star. The core is the hottest layer of of a star and it's made of hot, dense gas in the plasmic state. The core is the hottest part of the Sun and the Solar System. The elements oxygen, hydrogen, neon, nitrogen, magnesium, iron, and silicon are all formed in the suns core, which makes 25% of the sun. the force that the gravity creates makes the pressures and temperatures even hotter than in the core. The more hotter the core gets the bigger the star is because whatever is made in the core is what makes up the sun.
