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 art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

In this activity, learners explore the possibilities of clay as a natural material.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.
