Forces and Interacions

Students are exploring forces in science.  They are using what they have learned about magnetism's repelling and attracting forces to  design a vehicle that levitates and transports washers along a magnetic track


Students work to improve their levitating vehicles.  "My first was too small so it kept tipping and sticking to the track," Drew said.  "I put cardboard on it because when it was plastic I needed it sturdier," Lawrence said.

Students gather to test their levitating vehicles by adding metal washers until it no longer levitates or glides smoothly along the track.  This was Ava's test; her vehicle held 28 washers.
