The day started off with the students doing a demonstration where a rubber ball was dropped from a certain height and the time it took for the ball to hit the ground was measured. This entire demonstration involved a little bit of calculus for the students to do. The students charted and graphed their data into a spreadsheet.
After that, Bethany took over to talk about orbits. The class found what the velocity of the earth had to be with GalaxSee to keep the Earth in orbit and verified their findings using velocity and circumference formulas.
After lunch, the studnets use GalaxSee and the web tool GalCrash to model galactic collisions. Several different shapes and models were created. Then, Dave led a discussion on Dark Matter. The students then modeled how dark matter affected galaxies and then compared that to actual data.
