Direct linkSmith, P. Sean; Plumley, Courtney L.; Hayes, Meredith L. – Science and Children, 2017
This column provides ideas and techniques to enhance your science teaching. This month's issue discusses how children think about the small-particle model of matter. What Richard Feynman referred to as the "atomic hypothesis" is perhaps more familiar to us as the small-particle model of matter. In its most basic form, the model states…
