Time for Slime
Slime is more than just a fun pastime. Learners study the bonding of polymers using a mixture of glue, borax, and water. They then explore the properties of the slime and learn how the polymers in glue bond with ions in borax.

Wondrous Water
Students explore the different properties of water. They experimenting with different activities, each one explaining a different property of water. Students read an article "Small, Ues, But Might: The Molecule Called Water." and then...
Curated OER
Diffusion of Molecules
Students conduct a series of experiments to observe factors that impact molecular movement. In this molecular chemistry lesson plan, students drop food coloring in water with different properties (hot, with ice, with alcohol) and observe...
