Ninth graders explain how a scanning tunneling microscope works. In this chemistry lesson, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.

Fourth graders discover that scientists examine evidence from around the world in order to explain global climate change. They see that records of climate change exist, and describe photographs interpreting changes in glaciers over time.

Students explain five ways that coral reefs benefit humans and identify three threats to the reefs. They investigate the phenomenon of "coral bleaching" while examining ways to reduce threats to coral reefs.

Students set up their own composting bin. They observe and record their findings during a period of time. They describe the decomposing process as well.

Young scholars discover the concept of decomposition. They examine how it makes the soil more fertile and how it helps plants. They put a compost bin in their backyard and record their observations.

Students complete an experiment to determine how dirty the air is in their local community. They analyze images and discuss the varying degrees of air pollution. They discuss the results of the experiment.

Fourth graders work together to complete an experiment on air pollution. They identify visible and invisible forms of pollution. They gather their data in notebooks and analyze their results to end the lesson.

Learners test a variety of plastic bags to test its biodegradability. They record their observations and discuss them once the experiment is complete. They identify materials best suited to be placed in a landfill.

Students conduct an experiment to show how water gets contaminated through neighborhood runoffs.

Fifth graders investigate the process of water treatment. They listen to the book, "The Magic School Bus Visits the Waterworks," design a plan for a water treatment system, construct a water filter using various materials, and test the...

Fifth graders define vocabulary words regarding air quality. In small groups, they match magazine pictures or create illustrations for definitions and terms, and share the flash cards with their group.

Students perform a play that presents the causes and effects on people and the environment of the eight major air pollutants.

Students examine two devices used to clean up the air waste stream before it enters the atmosphere. They construct and use a wet scrubber and an electrostatic precipitator, and answer discussion questions.

Learners take a field trip to a local estuary and analyze water samples. They analyze and graph the data results, write an essay, and create a food web of their field site.

Students examine the path of pollution that was created by the Chernobyl accident. They discover how air pollution travels from one area to another and sequentially locate the countries where radiation traveled to.

Students investigate Bernoulli's principle of air pressure and how it relates to the lift of an airplane. Students identify various Aeronautical vocabulary terms. Students construct a paper glider and experiment with the control surfaces...
