Evidence of Work
In our first unit in chemistry, we studied cosmic chemistry. For the project, each group had to focus in on a specific part of stellar life. Our group decided to focus in on stellar death. To show this, we made a stop motion video explaining the different ways that stars can die and what types of stars cause these deaths. The main ways that stars can die are supernovas, black holes, planetary nebula or neutron stars. The cause for these different deaths is the mass of the star. The largest stars end in a super nova, slightly smaller ones end in black holes, etc. |

Content
Subatomic Particles- a particle smaller than an atom (for example a neutron) or a cluster of such particles (for example an alpha particle).
Fission- a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into 2 or more smaller, lighter nuclei.
Fusion- combining lighter atomic nuclei to form a heavier nucleus.
Radioactive Decay- the loss of elementary particles from an unstable nucleus, ultimately changing the unstable element into another more stable element. There are five types of radioactive decay: alpha emission, beta emission, positron emission, electron capture, and gamma emission.
Half-Life- the amount of time it takes for half of a particle to decay. The half-life of a particle can be used to determine how old it is by comparing the half-life to the amount of the particle that is left.
Nuclear Transmutation- the conversion of one element into another through fission or fusion.
Radiation- Radiation is released when unstable particles decay through radioactive decay. There are different types of radiation, the most harmful being gamma rays.
Nucleosynthesis- The process of a new element being created by combing two elements. Nucleosynthesis is done in the core of stars.
Alpha Particle- An alpha particle is the same as a He-4 nucleus, with two protons and two neutrons. Alpha particles are released during alpha decay.
Beta Particle- A beta particle is a high speed electron that is emitted by the nucleus during beta decay.
Gamma Rays- A very high energy radiation that is emitted during the loss of a nuclear particle.

Reflection
This project overall went well. There were a lot of peaks in the project, however there were also some pits. One peak is that we worked well together. Everyone helped out a lot and we were able to get this done within the time period given. Another was that we all were good at a specific job, for example one of us was good at drawing and did the animations.
However there were also some pits along the way. One pit was that the time that we were doing the project was very packed because we had PSATs and the homecoming rally, and the next week we had a test, and multiple guest speakers. Another pit is that we had to do voice recordings for the video and nobody wanted to hear their own voice.
