Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

Students research and discuss issues surrounding the atomic bomb and the concerns it raised and the consequences of dropping the atomic bombs on Japan. A variety of sample questions are provided to engage discussion.

A mix of scientific details and background information about the well-known sites of radiation attacks or accidents. This topic may open up details that you may consider as sensitive, and could be upsetting to some pupils. This is a...

Students critically investigate the issues surrounding the dropping of atomic bombs on Japan. They conclude if dropping the bombs was a correct decision or not and support their conclusions with documentation. Students tie in atomic...

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

In this atomic energy activity, learners read about Linus Pauling, who spent years making the public aware of the dangers of nuclear weapons. They answer questions about his work and the social responsibility he took on which led to the...

In this thermochemistry worksheet, students solve a variety of problems including finding heats or reactions, determining specific heats of substances, finding the amount of energy released in a calorimeter determining the final...

From the Atomic Archive - the online companion to the award-winning CD-ROM. This page (and the several that follow from it) paint a picture of the events which would occur if an H-bomb was dropped pon New York City. The effect of the...

A wonderful PBS biography of a great man. This contains many personal touches, yet does a fine job of describing Bohr's scientific work. But it's best at Bohr the man. Nice quotes, one in the middle, one at the end.
