Rollercoasters




 In Science we have been exploring potential (stored) energy and kinetic (movement or working) energy.  We used pool noodles sliced in half horizontally for the track, and marbles for the rollercoaster cars.  The students discovered how to give more energy to their marbles to travel over hills or through loops.  After completing a number of challenges with our rollercoasters, the students explored more complex designs.  This was a project where everyone needed teammates.

We have been watching some Rube Goldburg machines to see how they use potential and kinetic energy.  Here is a link to one of our favourite designs: http://m.youtube.com/watch?v=cv5WLLYo-fk
