Water is essential to Earth's living system, the biosphere. In this lesson, students determine the types of living things within an outdoor study site, use a taxonomic key to determine the predominant land cover type of their site, then predict the... (View More)

In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this... (View More)

Students begin by determining dew point using an aluminum can, stirring rod, ice and thermometer. Air temperature is also measured and recorded. Students then use those two data in conjunction with the Lifting Condensation Level approximation, to... (View More)

In this activity, student teams will create a controlled experiment by building ecosystems in two 2-liter bottles. Teams determine the control conditions of both bottles, identify a test variable, and run the experiment for several weeks to... (View More)
