Coins are everyday objects which tell a lot about the people who use them.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static
