In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners explore how nanosized structures can create brilliant color.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

This lesson introduces learners to the world of nematodes (roundworms).

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

In this activity, learners model a population of deer and see how the number of deer changes over time.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this activity, learners examine nanoscale structures of common things.

In this activity, learners collect worms and then observe how they move.
