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

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

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

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

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

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.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

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

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.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

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

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

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

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

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.
