Every year I love to give the kids a “dancing corn” experiment. They simply observe corn as it sinks in vinegar…They then get to add the “catalyst” or “activator” and ta da! IT DANCES! The smiles and giggles make cleaning up the mess Well worth it!
Preschool has had 3 great weeks with simple machines- first playing with my models, second using simple machines from around the class and house and they used wedges and screws this week. They hammered nails into stumps (good backyard activity) drilled holes into pumpkins, screwed into Styrofoam, matched nuts and bolts and used pizza cutters to slice dough!
