This web site is an online exhibit about Marie Curie, the discoverer of the radioactive elements polonium and radium and the first person to win two Nobel prizes. The exhibit provides an interactive account of Marie Curie's life, complete with photographs, maps, and links to more information. This is part of the Center for the History of Physics of the American Institute for Physics.
9-12: 1A/H3bc. In science, the testing, revising, and occasional discarding of theories, new and old, never ends. This ongoing process leads to a better understanding of how things work in the world but not to absolute truth.
1B. Scientific Inquiry
9-12: 1B/H8. Scientists' nationality, sex, ethnic origin, age, political convictions, and so on may incline them to look for or emphasize one or another kind of evidence or interpretation.
1C. The Scientific Enterprise
6-8: 1C/M7. Accurate record-keeping, openness, and replication are essential for maintaining an investigator's credibility with other scientists and society.
6-8: 1C/M8. Scientists' personal interests and viewpoints can influence the questions they investigate.
9-12: 1C/H6ab. Scientists can bring information, insights, and analytical skills to bear on matters of public concern. Acting in their areas of expertise, scientists can help people understand the likely causes of events and estimate their possible effects.
3. The Nature of Technology
3C. Issues in Technology
6-8: 3C/M9. In all technologies, there are always trade-offs to be made.
9-12: 3C/H5. Human inventiveness has brought new risks as well as improvements to human existence.
9-12: 3C/H6. The human ability to influence the course of history comes from its capacity for generating knowledge and developing new technologies—and for communicating ideas to others.
4. The Physical Setting
4D. The Structure of Matter
6-8: 4D/M5. Chemical elements are those substances that do not break down during normal laboratory reactions involving such treatments as heating, exposure to electric current, or reaction with acids. All substances from living and nonliving things can be broken down to a set of about 100 elements, but since most elements tend to combine with others, few elements are found in their pure form.
9-12: 4D/H3. Although neutrons have little effect on how an atom interacts with other atoms, the number of neutrons does affect the mass and stability of the nucleus. Isotopes of the same element have the same number of protons (and therefore of electrons) but differ in the number of neutrons.
9-12: 4D/H4. The nucleus of radioactive isotopes is unstable and spontaneously decays, emitting particles and/or wavelike radiation. It cannot be predicted exactly when, if ever, an unstable nucleus will decay, but a large group of identical nuclei decay at a predictable rate. This predictability of decay rate allows radioactivity to be used for estimating the age of materials that contain radioactive substances.
4E. Energy Transformations
9-12: 4E/H6. Energy is released whenever the nuclei of very heavy atoms, such as uranium or plutonium, split into middleweight ones, or when very light nuclei, such as those of hydrogen and helium, combine into heavier ones. For a given quantity of a substance, the energy released in a nuclear reaction is very much greater than the energy given off in a chemical reaction.
8. The Designed World
8C. Energy Sources and Use
9-12: 8C/H3. Nuclear reactions release energy without the combustion products of burning fuels, but the radioactivity of fuels and their by-products poses other risks.
10. Historical Perspectives
10G. Splitting the Atom
9-12: 10G/H1b. In their laboratory in France, Marie Curie and her husband, Pierre Curie, isolated two new elements that caused most of the radioactivity of the uranium mineral. They named one radium because it gave off powerful, invisible rays, and the other polonium in honor of Madame Curie's country of birth, Poland.
9-12: 10G/H4b. Nuclear weapons and energy remain matters of public concern and controversy.
9-12: 10G/H5. Radioactivity has many uses other than generating energy, including in medicine, industry, and scientific research in many different fields.
12. Habits of Mind
12A. Values and Attitudes
9-12: 12A/H5. Curiosity motivates scientists to ask questions about the world around them and seek answers to those questions. Being open to new ideas motivates scientists to consider ideas that they had not previously considered. Skepticism motivates scientists to question and test their own ideas and those that others propose.
