This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.
