This video segment from Swift: Eyes through Time introduces and explains theories of the origin of gamma-ray bursts.

In this activity, students study gas laws at a molecular level. They vary the volume of a container at constant temperature to see how pressure changes (Boyle's Law), change the temperature of a container at constant pressure to see how the volume changes with temperature (Charles’s Law), and experiment with heating a gas in a closed container to discover how pressure changes with temperature (Gay Lussac's Law). They also discover the relationship between the number of gas molecules and gas volume (Avogadro's Law). Finally, students use their knowledge of gas laws to model a heated soda can collapsing as it is plunged into ice water.

Learn how scientists regulate a nuclear reactor in this animation-enhanced essay from the FRONTLINE Web site.

Featuring images of glacier formations, this interactive resource adapted from the National Park Service explains what glaciers are, where they are found, how they form, and how they move.

In this video adapted from the Encyclopedia of Physics Demonstrations, learn how a glass beaker vibrates at a specific frequency and how resonance can force it to shatter.

This video segment adapted from NOVA/FRONTLINE looks at the future of global warming as developing nations, including India and China, increase their need for energy.

Is the hydrogen car the answer to global warming? This video segment adapted from NOVA/FRONTLINE looks at the pros and cons of this developing technology.

This video segment adapted from NOVA/FRONTLINE examines the greenhouse effect, its role in keeping Earth habitable, and the industrial changes that have led to an increase in the planet's average temperature.

This video segment adapted from NOVA features the youngest rock formations in the Grand Canyon, lava dams, and how they are subject to the eroding power of water.

In this video segment from NOVA scienceNOW, learn about the effects of gravity as astrophysicist Neil deGrasse Tyson falls through a virtual hole through Earth's center.

In this video segment adapted from NOVA, a meteorologist explains how an unusual weather pattern led to one of the most devastating floods of this century.

Build your own miniature "greenhouse" out of a plastic container and plastic wrap, and fill it with different things such as dirt and sand to observe the effect this has on temperature. Monitor the temperature using temperature probes and digitally plot the data on the graphs provided in the activity.

Explore how the Earth's atmosphere affects the energy balance between incoming and outgoing radiation. Using an interactive model, adjust realistic parameters such as how many clouds are present or how much carbon dioxide is in the air, and watch how these factors affect the global temperature.

Make your own miniature greenhouse and measure the light levels at different "times of day"--modeled by changing the angle of a lamp on the greenhouse--using a light sensor. Next, investigate the temperature in your greenhouse with and without a cover. Learn how a greenhouse works and how you can regulate the temperature in your model greenhouse.

Metals are grouped according to their characteristics. This video segment uses the periodic table for an in-depth discussion.

Students will observe and perform experiments with the elements sodium, potassium, calcium, magnesium, sulfur and phosphorus. Conclusions will be made about trends down groups, across periods and relating to acidity/basicity of metal oxides vs. nonmetal oxides

We are bombarded by new foods every time we go into a grocery store or watch television. Where are all of these foods coming from? Food science is the answer. This AFNR unit introduces several aspects of food science. Students investigate the issue of food safety, the chemistry, biology and physics involved in making some foods, and create a package design to market a new food product. This unit features 6 lessons and 8 files. Lessons are aligned to NGSS.

Create a cookbook to learn Standard Operating Procedures for food safety and environmental monitoring. Test for proteins, carbohydrates, and lipids and compare plant and animal protein. This unit features 5 lessons and 16 files. Lessons are aligned to NGSS.

Are soybeans everywhere? Really? Check ingredient labels in a variety of cookies, peanut butter, soups, chips, chocolate candy, microwave popcorn and other processed snacks. Many of the foods we eat include soy ingredients: soy protein, soy flour, soy grits, soy lecithin, and soybean oil. Use the 5E science instructional model with a series of experiments to explore the properties of water and answer the question: What makes “NesQuik™” quick? This unit features 1 lesson and 2 files. Lessons are aligned to NGSS.

Make biochar, a soil amendment, by making and using a model top light updraft (TLUD) pyrolysis kiln or oven. This unit features 1 lesson and 1 file. Lessons are aligned to NGSS.
