In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

Educator Amy O'Donnell from the American Museum of Natural History guides learners to create a diorama of a coral reef.

In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

In this activity, learners make balloon models of disease-causing bacteria.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

In this activity, learners imagine the path their food takes from planting a seed, all the way to sitting on their kitchen counters. Explore concepts for each step food takes to reach your home.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
