In this activity (on pages 29-35), learners examine water pollution and filtration.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

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

In this activity, learners create a biosphere in a baggie.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this activity, learners explore how salt water freezes in comparison to fresh water.
