In this activity, learners explore the different salinities of various sources of water by taste-testing.

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

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

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 compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity, learners will explore the water cycle by creating a small atmosphere.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

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 use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.

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

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.
