Seventy percent of the air pollution in China is due to car exhaust. Under the umbrella of environmental chemistry, learners extensively explore air pollution. From the makeup of our atmosphere to sources of major air pollutants, classes...

Tired of your students taking you for granite? Use a unit that offers multiple hands-on weathering and erosion labs and interactive activities. Some of the exciting lessons include planning a tour of Australia, using ice...

Students explore the causes of erosion and observe how different surfaces erode differently. They recognize erosion and predict what type of erosion caused it. In addition, they predict the outcomes of erosion on different materials.

In this biology lab, students will investigate whether acid/acid rain affects the germination of seeds through the use of observation, experimentation, data analysis, oral presentations, and scientific writing.

As part of acid rain study, (environmental chemistry lab) middle schoolers investigate the differences in pH of soil samples. They will collect and dry samples from the local prairie including grassland, transition, forest and riverbank...
