Fourth graders completed a unit on magnetism where they learned about the connections between the properties of magnets, the technological innovation of the maglev train, and the field of transportation engineering. They’ve explored several properties of magnets during a series of hands-on investigations. Through careful observations, students were able to draw conclusions about the properties of magnets (e.g., opposite magnetic poles attract, and like poles repel). They then applied this knowledge as they used the Engineering Design Process to design their own maglev systems that can transport small stones from one side of a track to the other.
