Roller Coasters

During science, we were learning about roller coasters.  We learned about gravity and momentum.  Today, we got to be roller coaster engineers!  Our roller coasters are still under construction, but once they are ready to be tested and put to use, we will post a video clip.  Enjoy the pictures!

  1. It was really fun making those roller coasters.
    Maybe we can make them again with are younger brothers and sisters next year!
