Anatomy of a Firework

There's more to a fireworks display than meets the eye. This interactive activity from the NOVA Web site looks at the technology behind each burst of light.

Birth of a Supernova, Type II

In this interactive activity from NOVA Online, learn about a type of exploding star — a Type II supernova — that is so large it has a mass 10 times greater than the mass of our Sun.

Blacker Than Black

In this video adapted from NASA, two members of a NASA research team working to produce carbon nanotubes share some background behind this new technology, show examples of how it will be useful, and explain the various tests being performed to ensure readiness for spaceflight.

Chemical Bonds

This interactive activity developed for Teachers' Domain demonstrates how attractive forces between atoms create chemical bonds, resulting in the formation of molecules and compounds.

Developing the Periodic Table

This video excerpt from NOVA: "Hunting the Elements" looks at how early chemists developed the periodic table of elements.

Graphing the Periodic Table

This interactive activity from the American Chemical Society presents the properties and electron configurations for all the elements in the periodic table. Discover patterns by plotting the elements' properties according to their place in the table.

Group Metals

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

Igniting Chemistry in Fireworks

Students learn about the concepts of spectral chemistry, combustion, and the nature of fire through the use of visually rich fireworks resources. Optional resources address chemical reactions for those who want a more advanced chemistry lesson.

Island of Stability

In this video segment adapted from NOVA scienceNOW, follow scientists in their quest to understand how stable elements are made and how to create the elusive element 114.
