Roller Coasters

This first week back from break, we worked on finishing our roller coasters.  The group I was in, with Michael, Gus, and Eddie, thought we had finished our roller coaster before the break, but we decided to change it before we had to present it to the second graders.  We also learned about potential energy, energy that can happen, and kinetic energy, energy caused by movement, along with acceleration, speed and velocity.

On Wednesday, we showed the coasters to the second grade, which was an interesting experience.  I was surprised at the questions some of them asked, some of them were questions I never would have thought of.  Our roller coaster was one of the biggest, but we couldn’t get it to work consistently for the second graders. Overall, I really enjoyed the roller coasters, building, learning, and presenting, and I look forward to hover crafts in the coming weeks
