In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

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.

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

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 simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake

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

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

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
