In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

To convey the concept of how animals adapt to survive, this game asks learners to imagine what adaptations a given animal would need to live in a certain environment—including environments where such

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this activity, learners investigate variations in human traits. This allows learners' natural curiosity about their identity to draw them into the study of heredity.

Learners observe glow-in-the-dark objects in a homemade light-proof box. Objects can include glow sticks, glow-in-the-dark toys, and toys with fluorescent paint.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

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

In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre

In this activity, learners will conduct an experiment to discover methods of reventing foot mold growth on food.

Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.
