Lights, shadows, action, and inquiry await your artistic scientists. They explore the way light travels, absorbs, reflects, and transmits through shadow play. They create folktale-inspired shadow puppets, explore the science of light,...

Go to extremes to illustrate boiling point! Junior chemists explore the effects of heating and cooling on polar and non-polar substances. The interactive allows users to raise and lower the temperature, set specific temperatures, and...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Clever! Collaborative groups of environmental scientists create a museum exhibit and presentation for an energy-using activity such as heating a home or transportation. They must compare past to present use of energy for that particular...

Have individuals wash their hands with soap and water, give one of them a yeast-covered piece of candy, and then have him shake hands with the person next to him. Handshakes continue down the line until everyone in the class has had...

Third in a set of lessons regarding reservoirs, dams, and hydropower, this involves a two-day hydropower plant simulation. Collaborative groups build, maintain, and finance the plant. The transparency of the reservoir setup can be...

Students work together to complete a simulation on drought days. As a class, they discuss their results and compare water usage of the past to current numbers. After reading short excerpts, they answer discussion questions and review as...

Students explore how PCR works through various activities. In this biology activity, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Students telecommunicate and use the US Mail to network students from five biomes in the United States in order to monitor water quality in each area. They have e-mail pals and exchange materials representative of themselves and their...

Students describe the body form and major anatomical structures of squids and describe some unusual or unique features of newly-discovered deep water squid species. They infer what types of food squids use from their anatomical features.

First graders participate in a simulation in which they discover the community has been using too much water. In groups, they research the various ways the water is being used and create a home survey. They show the water usage of the...

Learners 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.  Learners investigate a simulated tree ring...
