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 fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

By building a model of a lung and diaphragm, learners discover the function of various parts of the body's respiratory system.

To discover the risk and protective factors involved in substance addiction, learners play a game of chance to determine whether a fictitious child is likely or unlikely to abuse drugs.

In this demonstration (9th on the page), learners explore eyewitness memory and how memories differ amongst individuals. While the rest of the group is minding their own business (i.e.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Water treatment on a large scale enables the supply of clean drinking water to communities.
