A very nice site with all sorts of information on helium, including good summaries on isolation and uses of helium.

Comics featuring helium and including nice graphics for a presentation.

A great source of information on helium. Exceptionally thorough and well written.

Here you can find lots of great information about helium. Learn about its electrons, where it exists in nature, and about the element itself!

This site from Chemicool provides a set of tables summarizing a great deal of information on helium and its properties.

The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about helium, Donald Duck voices, and floating balloons. [4:45]

[Free Registration/Login Required] Build your own helium atom and make sure it has the correct number of protons, electrons, and neutrons on this site. Site also includes a small quiz on the topic.

Dilution fridges owe their cooling power to the incredible element helium. This animation illustrates how dil fridges exploit the element's properties to make things very, very cold.

This Cornell University Astronomy Department site surveys the the hydrogen and helium burning that takes place in the evolution of a red giant. Links to related information.

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.

A lesson and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'

This site has a definition and properties of Leptons, the "Basic building blocks of matter." There are links to table of properties and more information.

Build elements and molecules using neutrons, protons, and electrons. Choices include helium, carbon, oxygen, aluminum, water, and salt.

Fusion is the process at the core of our Sun. What we see as light and feel as warmth is the result of a fusion reaction: hydrogen nuclei collide, fuse into heavier helium atoms and release tremendous amounts of energy in the process.

Did you know our sun in composed of mainly hydrogen and helium? This infograph reviews over all the chemicals that can be found in our sun.

Describes how a star becomes a red giant, the structure of a red giant, core-helium fusion, lifetime predictions, and the position on the HR diagram.

This is the homepage of all of the archived information about and from the Galileo Mission. Included is data from the flybys of Venus, Earth, Moon, and Asteroids Gaspra and Ida, as well as the current data from Jupiter and its moons. See...
