In this multi-part activity learners examine non-point water pollution.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

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

Many people get water from a source deep underground, called groundwater.

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

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

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

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

In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not

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

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

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

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.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

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