No matter where we live, each and every one of us depends on transportation to some degree. Whether it's in our own personal cars or on public transportation shared with others, transportation is an important technology developed by engineers. Our focus in this unit will be on the Maglev train!
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!
