Build a Watershed
What's the best way to learn how watersheds work? Build one! Combining engineering, the water cycle, and ecology concerns, the activity is the perfect fit for an interdisciplinary unit. Teams construct a model watershed with simple...
Curated OER
Water Pollution
Students study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and to...
Curated OER
Formation of Rain
Students sequence the steps leading to the formation of rain, and design a model to represent these steps. This task assesses students' abilities to classify, generalize, infer, interpret and communicate data, and construct a pictorial...
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson plan, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

What's In Crude Oil?
Students investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.
