As part of the third graders' student of forces and motion, they experimented with creating cars that were moved without students touching them. Students worked together to create unique car designs using their knowledge of magnetic fields. When they held magnets with two south poles (or two north poles) near each other, their cars moved forward. When they placed magnets with a south and a north pole near each other, the car moved toward them and the magnets stuck together.

Students used the engineering design process and made improvements along the way. It was wonderful to hear them share their designs and understandings of magnetic fields and forces with each other.
