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 outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

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 wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

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
