Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

In this water activity, learners discover ways to move water across the water table.

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

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.

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.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

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 a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
