Due: September 29, 2015

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:

_ Ally

_ Maggie

_ Molly

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

Materials we need: sponge paint hot glue gun scissors plastic bag

How are we going to scale this? What is our scale? Example 1 inch = 500 miles 45 million miles = 1 centimeter

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
 * A nuclear fusion happens inside a star. When the star's iron fuses, it goes to the peak of the binding energy curve, making the star.

2. Which is hotter a red star or a blue star? Why? _/4 pts
 * A blue star is hotter because according to scientists it represents it better then red, which represents a cold star. The hotter something is, the the frequency of radiation it emits. Blue light is a higher frequency than a red star, making red represent cooler and blue represent hotter.

3. What are the 6 types of stars? /6 pts The 6 types of stars are white dwarf, brown dwarf, neutron star, main sequence stars, red giant stars, and variable stars. White dwarfs are the remnant of the stars core, because the outer envelope of the star merges with the interstellar space. Brown dwarfs are failed stars, and smaller than a main sequence star. A neutron star, like a white dwarf, is more of a remnant of a star then an actual star. It goes through a supernova explosion, leaving behind its super dense core. A main sequence star is where the majority of a stars life is lived, it forms when a nuclear fusion commences in its core. Red giant stars are when all the hydrogen fuel in its core transitions off the main sequence. Variable stars are stars that are smaller and variate in their twinkle and brightness.

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

This project helped me understand the star better because I got to visualize it. I also had to research the parts of the star to write the paragraph. While labeling the parts of the star, I learned more about where the layers of the star are placed and how it all works together. This project helped me visualize a star in a smaller scale and see where the layers are placed.

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

Yes, I believe everyone worked together on this project equally. We all talked to each other while working. Two of us would paint, one of us would direct, and the other would write on labels to label the parts of the star. We also had to hot glue the labels on, and we all worked together on that.

Write a description in your own words describing how one layer of a star The core is a very important layer of the star.The core is the center of the star, and it shines because of thermonuclear fusion oh hydrogen and helium that goes into the core, releasing energy that makes the core radiate. After a while, the star's core will start to shrink and the intensity of radiation from the surface goes up, creating radiation pressure on the outer shell, pushing those layers away, creating a planetary nebula. After its life cycle, every star dies. it goes through all the phases before the core shrinks, not being able to maintain any more pressure, and dies.
