 | Magnetic forces between a pair of objects are unique. They don't require that two objects be in contact with each other in order to make an object move. WAIT...WHAT? Objects that are magnetic don't have to touch a magnet in order to move it? Check out these examples... |
Third graders will be using this new found knowledge in their cotton ball obstacle courses. How can they get their cotton ball to move using magnetic forces and NOT the wind? Check back soon to see how they met the new criteria for this engineering design challenge!
