Interactions In Science And Society guides students through the complex web of connections between science, technology, society and the environment, preparing them to make informed decisions by examining issues that illustrate these interactions.
Acid deposition - much of it from power plants in the Midwest of the United States - results from an expanding economy, affluent lifestyle, convenient transportation, and plentiful energy, and it can damage the lakes, forests, buildings, and artefacts - especially in the North-east and Canada. The situation sets the East against the Midwest, and Canada against the US, both politically and economically. The chemistry of acid rain can vary, and opinions about the nature and severity of the problem and the best way to deal with it diverge widely.

In the South-west of the United States much of the water is to saline for drinking or good crop growth, waste purification is costly, and scientists are trying to develop salt-tolerant plants. The water needs of Los Angeles may leave surrounding areas with inadequate water. In the North-west, the need to generate electrical power conflicts with the biological needs of salmon, the prosperity of the fishing industry, and the values and treaty rights of Native Americans. In Wisconsin, the paper industry's investment in expensive technology to keep rivers clean has not satisfied environmentalists, who claim that the waste water is still a healthy threat for.

We need water for every human activity, but our aquifers are in danger. We use far more than can be replenished by the natural process of recharge, and many people have found their wells or other sources of water contaminated by industrial or agricultural run-offs all landfills. The federal government and the United States regards water quality as a state or local concern, but water in the lowest aquifer can travel long distances. Technology is developing ways of sealing land fills and testing water, but cleaning up contaminated aquifers is expensive and not totally reliable.

Human activity is affecting the natural cycles of the Earth's climate. Carbon dioxide from the burning of fossil fuels is creating a possible 'greenhouse effect'. Climatic changes have enormous impact on our economies. Computer models and satellites have improved our forecasts, especially for the very near future. The Global Climate Protection Act of 1989 requires the government of the United States to develop a policy towards the suspected cause of global warming, but our knowledge is still very imperfect. Some possible solutions would be drought resistant crops, reforestation, and alternative energy sources.

Technology has helped create our waste disposal problem, and may help us solve it. Our disposal options are dumping, burying, burning and recycling, now economics have favoured burial in landfills. Interviews with experts and citizens involved in plans to put a large landfill near New York dramatise some of the political and scientific issues involved in waste disposal. To reduce waste and recycle more would require a change in attitudes and lifestyles.

The Energy In Action series takes students beyond the basics to help them understand the many forms of energy, why it behaves the way it does and how it can be harnessed. The series covers the five main forms of energy - mechanical, chemical, nuclear, heat and electromagnetic - and the importance of conserving this valuable resource.
What is heat energy, where does it come from and how does it relate to chemical energy? 'Heat & Chemical Energy' teaches students that heat energy comes from the motion of chemical atoms and chemical energy is stored in the bonds that link atoms together. This programme helps students discover how chemical reactions can give off heat energy and how heat can help release the stored chemical energy in fuel. Students will investigate: how heat travels, through engaging demonstrations that illustrate the methods of conduction, convection and radiation; and how scientists measure (Joules) - the energy stored in food - by constructing a calorimeter and burning a peanut.

In this video students will discover the power stored inside the atom. The key concept is that huge amounts of energy can be released when the forces that hold the nucleus of an atom together are disturbed. That can happen through fission, the splitting of an atom's nucleus, or fusion, the combining of protons and neutrons from two different atoms.
Pioneering scientists Lise Meitner and Marie Curie are introduced, and students learn how their research led to a greater understanding of the atom. Students also learn that although nuclear energy is a clean, almost inexhaustible energy resource, there are safety issues that must be addressed. Includes a hands-on demonstration to help explain nuclear chain reactions and the energy they release.
