2. Interacting Magnets!

While our focus in this unit will be on transportation engineering, fourth graders will also be focusing on magnetism!  Our first focus with magnets is learning how they interact with other magnets!  We created a model and then revised it based on our experiences.  Our conclusion today...when the poles of two magnets that face each other are the same (N-N or S-S), the poles will repel.  When the poles of two magnets that face each other are the opposite, the poles will attract!
