Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

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

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 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.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

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

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

You just ate a big meal and feel heartburn coming on. You take an antacid and feel better. Why? Heartburn is caused by stomach juice (an acid) burning the esophagus.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!
