In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity, learners explore patterns and sequences as they observe fictional plant growth.

In this quick activity (page 2 of PDF), learners will play a game using their observation and listening skills, interpreting clues from each other to deduce their secret animal identity.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

In this activity, learners create a sound visualizer from common materials to help see the vibrations created by sound. Sounds from a tone generator make salt dance on a vibrating balloon membrane.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

In this game, learners cross off or color bingo squares in response to questions about their traits.

In this activity learners will investigate magnetic and non-magnetic items in a sensory bottle.

Many common household cleaners are antimicrobials.

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

In this activity, learners will explore the roles of different animals in the food chain. They will create their own food chain using organisms of their choice.

In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity, learners make instant ice cream without using a freezer.
