Now that you have a good understanding of nuclear processes, it's time to illustrate your knowledge. In this modeling activity, you will develop a physical model or diagram to illustrate each of the following nuclear processes: • Fission • Fusion • Alpha Decay (a) (type of fission reaction) • Beta Decay (B) • Gamma radiation (y) All five of your models or diagrams should include: ✔ Identification of an element before and after a nuclear process (For alpha, beta, and gamma radiation, select a beginning element from this radioactive isotope list.) ✓ Identify any change from one element to another that can occur due to the process ✓ The number of protons and neutrons in the nucleus of an element before and after the nuclear process ✓ The identity of the emitted particles (i.e., alpha, beta, and gamma) ✓ Identify any energy releases or energy gains (kinetic or electromagnetic) during the nuclear process. (Hint: Do fission and fusion reactions need some initial start-up energy? Check the lesson for the answer.) ✓ Describe how the nuclear process compares to a similar chemical process in terms of energy Since gamma radiation can be released with alpha or beta decay, a gamma radiation model can be paired with an alpha or beta dogay model if desired

Another series of nuclear reactions that can produce energy in the interior of stars is the cycle described below. This cycle is most efficient when the central temperature in a star is above 1.6x10' K. Because the temperature at the center of the Sun is only 1.5×10' K, the following cycle below produces less than 10% of the Sun's energy.

Thinking Nuclear Power is a perfect example of exponential relations. Canada produces over half of its electricity using nuclear reactors. One of the major problems associated with nuclear power generation is the radioactive waste. Currently all nuclear waste is stored on site at the power plant and there is no solution for the long term waste. After completing this Grade 11 Functions and Applications course, you have been put in charge of Energy Production in Canada. A) What would you do with the long term waste? B) How would you take care of Canada's energy needs for the future?
