First graders explored the power of the magnetic force. First we felt the push and pull of magnets. Like poles repel and opposite poles attract.
Can the force travel through solids and liquids? Scientists tried to remove washers from a jar of water without spilling a drop.
Is the force strong enough to move a paper clip through solids- fabric, plastic, paper, cardboard, or fun foam? We also tried layering the objects. Is it possible to move a paperclip through the lab table, chair, or even our hand?
