The Big Bang: For our first project of the year, we learned about our universe and how it started. One of the most probable theories of how the universe started, is The Big Bang. Basically, the big bang is a single explosion that happened 13.8 billion years ago and ever since that explosion, the universe has been expanding. The three strongest pieces of evidence to support this theory are redshift, the cosmic microwave background and the process of a star’s life and how they create all of our elements. We were asked to make models to show each of these and how they support the big bang. In my team, I had Liliana, McKenna, and Priscilla. The Redshift and Expansion Model: https://spark.adobe.com/video/CRYFB3DtSmwvc This is the model to show what Redshift is and how it shows that the universe is expanding. The Cosmic Microwave Background Model: https://spark.adobe.com/video/ar4r1CvCjcCJz This is the model to show the Cosmic Microwave Background and how it supports the theory of the Big Bang. The Life Cycle of Stars Model: This is our model to show the Life Cycle of Stars and how they create the elements. Low mass: Low-mass stars start in a planetary nebula where there is a low amount of matter. A low mass star starts with hydrogen and from there create all elements up to neon. From there it cools and expands due to the lack of fuel (hydrogen) and releases the elements. From there all that excess material forms a planetary nebula. From there it continues to cool to become a white dwarf. The final stage of a low mass stars life is a black dwarf which is basically nothing, it is when a white dwarf cools enough that it no longer puts off a sufficient amount of temperature. High mass: High-mass stars are created when a stellar nebula has a lot of matter. A high mass star is capable of making up to element 26 during its first stage. Unlike a red giant, a super red giant collapses in on itself layer by layer. When a red giant collapses as far in on itself as it can it releases a burst of energy, creating a giant explosion. From here it will become one of two things. If the energy is more than the mass the once high mass star will become a neutron star, but if the mass is greater than its energy, it will become a black hole.

In this video, I talk about what Redshift is and how it shows us that our universe is in fact expanding. I used video clips from other youtube videos and I recorded my voice explaining this topic. Enjoy!

I did draw this myself. Also, note that in the Stellar Nebula there are four Hydrogens (H) at the top, then those Hs are added together to make two Heliums, then those add together to make one Beryllium. Enjoy!
Our first project of the year in my Game Design class was to work with and learn about the saber plugin in Adobe After Effects. The saber plugin lets you adjust the glow and brightness, the sizing and so much more. Something really cool that the plugin lets you do are that you’re not limited to just making a lightsaber, you can make words flow, make a sphere, and more. For this project, we filmed a video with a partner of us sword fighting with sticks. We then put that footage into After Effects and put the lightsabers onto those sticks. In my video, I learned how to keyframe the sabers frame by frame, make multiple masks and keyframe those, and I learned how to customize my own lightsabers. I really liked working with this plugin because you have so much freedom and when you want to do something, there is most likely a way to make it happen. I feel that it was a lot of work to move the lightsaber for EVERY frame. I really wish there was a way to lock it down to something that way whenever it moved the lightsaber would move with it. I did have some obstacles with learning how to make and keyframe the masks when I needed and when I needed them to not be there, but I think it turned out okay in the end. Overall I thought this project was really fun and a great way to start off the year! |
