In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

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.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

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 find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.
