Fifth graders in Ms. Dorsey’s science class did an energy investigation, considering the forces of potential and kinetic energy by creating their own roller coasters. The engineering challenge was for students to create a design using tape and toilet paper tubes that would maximize gravitational potential energy and turn it into kinetic energy. The students rolled marbles down the roller coasters and measured the distance the marbles traveled after exiting the coasters.  The hands-on approach to science got everyone excited and moving!
