"Hard" Data from Space

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

Before your learners excuse themselves to get a drink at the water fountain, prompt them to think about where that water comes from. A middle school science lesson encourages groups to research their community's source of drinking water,...

Did you know that California produces two thirds of the fruits and nuts consumed in the United States? That it produces almost one third of the vegetables? Did you know that scientists warn that California is facing the onset of a...

Fifteen million children under the age of five die each year due to diseases in their drinking water. Water pollution is the topic of lesson 34 in the series of 36. Scholars, through reading and discussing, study numerous aspects of...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

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...

Young scholars differentiate between point and non-point pollution and determine how the different types of pollution are harmful to aquatic ecosystems. They complete a series of tests on a sample of "polluted" water and a sample of...

Get lost at sea amid colorful ocean currents! Learners discover the patterns of movement and temperature in the North Atlantic's currents through a simulation, part of PBS's Weather and Climate series. The resource contains background...

Earth's vast ocean is full of mysteries! Science scholars discover the big-picture properties that influence its characteristics at different latitudes using a lesson from PBS's Weather and Climate series. After completing a background...
