This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

In this activity, learners examine antibodies and antibody recognition using a model.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.
