In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

Learners take on the role of environmental engineers as they design water filters.

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.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this activity, learners are invited to imagine the park of their dreams!
