Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.

This activity (on pages 24-29) combines science and art to introduce learners to how different animal pollinators spread pollen from one plant to another, and how certain shapes, colors, and smells of

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

This activity (on pages 19-25) is about fleas and ticks, which are common pet parasites.

This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.

In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

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.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

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

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.

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

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.

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.

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 outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.
