In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

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

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.

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.
