In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity, learners will explore how density is affected by temperature and how that can create currents.
