This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this outdoor activity, learners dig for and collect isopods (sometimes known as "roly-poly bugs" or "potato bugs" and other names).

In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

Learners take on the role of environmental engineers as they design water filters.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

In this health activity (located on page 4 of the PDF), learners will discover the importance of hand washing by observing mold growing on potatoes.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
