JaNoah and Jayden’s Magnetic Car Challenge (MS-PS2-1, MS-PS2-4)

JaNoah and Jayden are competing in a science fair challenge. Their task is to design a small car that can move without being touched. JaNoah uses a magnet under the car and another in his hand to push the car forward. Jayden sets up a ramp and lets gravity pull his car down. They observe and measure how the cars move, discussing how contact and non-contact forces influence the motion of their cars.

• GOT IT!

• I don't get it.

Match the force with its correct description:

• Magnetic force

• A force that acts at a distance, like gravity or magnetism.

• Non-contact force

• A non-contact force caused by magnets.

• Friction

• A force that requires two objects to touch, like pushing or pulling.

• Contact force

• A contact force that resists motion between surfaces.

Reorder the steps to describe how JaNoah’s magnet moves the car:

• The car begins to move away from JaNoah’s magnet.

• JaNoah holds a magnet near the car.

• The distance between the car and JaNoah’s magnet changes the force strength.

• The magnetic force repels the magnet on the car.

JaNoah notices his car moves faster when she uses a stronger magnet. What question could she investigate next?

• Does the car move faster with less friction?

• How does the strength of the magnet affect the car's speed?

• What happens if I add more wheels to the car?

• How does the ramp angle affect gravity?
