What we're studying:
simple machines, Newton’s Three Laws of motion, potential energy, kinetic energyOur Team Leader's favorite quote:

As you watch our Rube Goldberg Machine in progress, you will notice how hard we worked to accomplish the task of erasing a chalkboard. As you travel with us through the milky way, we will close the black hole and save the world from total destruction. We based this whole machine around the inclusion of different simple machines. We spent many days studying each individual machine and preparing our ideas with each group. This led to the creation of our unique Rube Goldberg machine, Lost In Space. While displaying our theme of “Lost in Space”, we show a ball rolling down the long satellites which starts a chain reaction. This proves that in the end, we save the world from total destruction!
