Evidence
This is the first project of our junior year chemistry class. For this project we had to choose one aspect of space and astronomy and how it connects and applies to the creation of new elements in chemistry. We chose to focus on stellar death, which is the process of how a star dies. The slide show on the right shows our initial planning and story boarding of our animation and the video on the right is our final product.

Content
Subatomic Particles- particles smaller than atoms
Fission- a nuclear reaction in which the nucleus of an atom splits into two or more nuclei with the release of large amounts of energy
Fusion- a nuclear reaction in which two or more nuclei fuse to form one nucleus with the release of large amounts of energy
Radioactive Decay- the process of an unstable atomic nucleus releases energy and mass through radiation
Half-Life- the time taken for a radioactive isotope to decay to half of its mass
Nuclear Transmutation- the conversion of one element or isotope into another element or isotope
Radiation- the emission of energy as electromagnetic waves or subatomic particles
Nucleosynthesis- the cosmic formation of complex atoms
Alpha Particle- a helium nucleus emitted by radioactive substances
Beta Particle- an electron emitted by radioactive substances
Gamma Rays- electromagnetic radiation originating from the radioactive decay of an atomic nucleus
Star- a large celestial body of hot, burning gas
Black Hole- a region in space where gravity is so strong, not even light can escape its gravity
Nebula- a cloud of luminous dust and gas in space
Supernova- an expanding star that ejects out most of its mass
Types of Stars:
-Blue Supergiant- a very large, bright, and hot blue star
-Red Giant- a very large and bright star with a relatively low surface temperature; approaching end of life cycle
-Blue Giant- a very bright and hot blue star
-Neutron Star- a very small and dense star that doesn't generate heat; created after supernovas
-Sun-like Star- stars that are similar to our sun
-White Dwarf- a very small and dense star; created after a star exhausts its nuclear fuel and explodes into a planetary nebula
-Red Dwarf- a small and cold star approaching the end of its life cycle
-Dead Red Dwarf- a red dwarf star that has stopped nuclear fusion
-Brown Dwarf- a gas heavy star that is bigger than a planet, but smaller than a star
-Dead Brown Dwarf- a brown dwarf that has stopped nuclear fusion

Conclusion
Overall, this project was very fascinating. It helped me view the universe in a new, mysterious way. It has made me even more curious to learn about the universe we live in. With this, we had a few high points with our project. One thing that went well was planning. We clearly had a plan as displayed with our storyboard. This helps keep our work organized and easy to follow. Continuing to create an outline of our project will help us achieve our goal with ease. Another thing that went well was teamwork and collaboration. Everyone was on the same page about what needs to get done and how to get it done. This also created a better work environment. If we continue to work well with teammates, everyone would be motivated to work hard. Despite our high points, there were areas that we struggled with. One thing was time management. Though we had a clear plan, it was tough to follow due to many interruptions in our schedule. In addition to our short time frame, we had much work to do. If we can stay focused and stay on task, our project may have looked better and more detailed. Another thing we struggled with was the lack of research. Again, due to our short time frame for this project, we had to cut some things short. Because of this, many things felt rushed and not explored well enough. If we could put more time and effort into doing quality research, our project would have been more informed and we would be able to understand the subject better.
