This video from NASA describes the GLAST satellite, which is equipped with a gamma-ray telescope, and shares some background about the kinds of extreme universal phenomena indicated by the presence of gamma rays.

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

This article is an overview of the life of Mohandas K. Gandhi and his acts of civil disobedience. Access to this resource requires a free educator login.

This is an extensive and very detailed chartmaker that allows students to create custom graphs/charts to analyze a variety of data. The default link compares life expectancy with average GDP per capita. There are educator resources with available lessons or use the tool in ways that work for your classroom instruction. This is one of the most detailed and extensive data tools available.

Gapminder Bubble Graph is a website with an interactive spatial and temporal datasets related to development, economics, demographics. These materials can work equally well for teacher-led or student-led activities.

Gapminder Dollar Street is a website with an interactive image set that depicts the reality of different development levels for families around the world. Divided by 4 basic income levels as well as by region. These materials can work equally well for teacher-led or student-led activities.

In this video segment from Garden Insects, learn about six varieties of spiders that live in one garden.

In this online book, Traci Gardner defines the process of standards-based writing assignment design and assessment with a research-based approach.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other. Balls, representing molecules, move within a cage container to simulate this phenomenon. A hair dryer provides the heat to simulate the heating and cooling of gas: the faster the balls are moving, the hotter the gas. Learners observe how the balls move at a slower rate at lower "temperatures."

It appears from the economic reports that the world uses gasoline on a very short supply and demand scale. The impact of any storm, let alone Hurricane Katrina, affects the costs at the pumps too quickly. Let's restrict our study to the continental United States.

Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. Examine kinetic energy and speed histograms for light and heavy particles. Explore diffusion and determine how concentration, temperature, mass, and radius affect the rate of diffusion.

Students learn how to collect information for a research paper. They also consider what questions to ask when collecting evidence.

This three-act math task utilizes videos and questioning to help students explore factors and multiples.

This subject explores the legal history of the United States as a gendered system. It examines how women have shaped the meanings of American citizenship through pursuit of political rights such as suffrage, jury duty, and military service, how those political struggles have varied for across race, religion, and class, as well as how the legal system has shaped gender relations for both women and men through regulation of such issues as marriage, divorce, work, reproduction, and the family. The course readings will draw from primary and secondary materials in American history, as well as some court cases. However, the focus of the class is on the broader relationship between law and society, and no technical legal knowledge is required or assumed.

Express yourself through your genes! See if you can generate and collect three types of protein, then move on to explore the factors that affect protein synthesis in a cell.

Build a gene network! The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.
