In this activity, you can create a toy that demonstrates The First Law of Thermodynamics or The Law of Conservation of Energy. By stretching the rubber band on the toy differently, you get to explore the effects of potential energy on kinetic energy. The activity webpage includes a fun how-to video for anyone.
In this activity, you will get the chance to design and build your very own roller coaster. As you are creating this coaster, you will apply concepts of potential and kinetic energy to make the marble go faster.
