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 (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners create a biosphere in a baggie.

In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.
