Making Chemistry Visible with Doug Ragan

Many chemistry teachers use models and diagrams to help students describe how matter behaves at the particle level. On April 14, 2022, Doug Ragan explained how he uses colored magnets in his classroom to represent things such as subatomic particles, states of matter, balancing chemical equations, types of bonding, molecular geometry and much more.
