Fourth and fifth graders explore soil by taking a simulated field trip under the earth. They go to an Internet site that runs a simulation which charges them with finding a source of pollution that could destroy all of Earth's soil, and...

Young scientists identify erosion, explain the causes of erosion, and name some techniques that can slow the process of erosion. Learners are divided up into groups of four and perform a simulation of soil erosion in class. The...

Students investigate healthy eating habits by researching livestock. In this food sustainability lesson, students research the negative impact factory farming has on our environment due to pollution. Students define agricultural...

Students determine how pollutants can travel though sediment and explore methods of pollutant removal. They conduct an experiment on porosity and permeability of soils and simulate an EPA "pump and treat" method for removing subsurface...

Students create models of the greenhouse effect using recycled 2-liter bottles. They discuss how their models compares to the real greenhouse effect the earth experiences.
