In this activity, learners will discover why there are holes in bread.

In this activity, learners make their own heat waves in an aquarium.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

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

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

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.
