Students study trees and their growth.  In this investigative lesson students work in groups to reconstruct a 50 year climatic history using a simulated tree ring. 

Bring together a study of two major scientific topics with a lesson on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn...

A video about the impact of climate change on butterfly populations and a PowerPoint about butterfly and bird adaptations warm science learners up for the activity to follow. Using a variety of tools that reprsent unique styles of bird...

A professional-quality PowerPoint, which includes links to footage of actual landslides in action, opens this moving lesson. Viewers learn what conditions lead to erosion and land giving way. They simulate landslides with a variety of...

The Mars Global Surveyor spent two years creating a mineral map of the planet Mars using thermal emission spectrometry. To help young astronomers understand this remote sensing instrument, have them simulate how data is collected and...

Students act as dendrochonologists working to reconstruct a 50 year climatic history. They make a personal timeline.

Young scholars investigate the lives of trees by examining ring cycles.  In this plant life lesson, students identify the field of study known as dendrochronology and discover its history.  Young scholars investigate a...

Students create a scale model of the affected area of the Chernobyl disaster. Using this scale model, they simulate the explosion and the resulting uneven dispersal of fallout due particularly to wind direction and weather conditions.

Students practice analyzing ice core samples to discover climate changes. Using the samples, they identify and graph the gas amounts. They use these numbers to determine their effect on global warming. In pairs, they complete a...

Nanoparticles have toxic effects on plant and animal life—even though you can't see them. The second lesson of a two-part series has young scientists conduct an experiment that exposes plant and animals to nanoparticle pollutants. They...

Pupils explore ways scientists prepare for a volcanic eruption. They observe films of earthquakes, oil spills, volcanoes and hurricanes. Students perform activities to demonstrate the relationship of viscosity to lava flow. They...
