13. Nuclear Energy: Fission or Fusion Fusion vs Fission http://www.youtube.com/watch?v=oIe1EDExxyg http://www.youtube.com/watch?v=oIe1EDExxyg

14. On page 61 -Make a chart with two columns titled Fusion and Fission. Nuclear Fusion Nuclear Fission

15. Let’s Read!!!- for 10 min As you read write characteristics of FUSION OR FISSION in the appropriate column Read the article titled Reading Science! Fusion or Fission Each note should only be 2-4 words Do not copy the whole sentence Focus on key ideas (first and last sentences in each paragraph)

16. Make a chart with two columns titled Fusion and Fission. Nuclear Fusion Nuclear Fission Now let’s fill in our notes. Check to see if you caught the main points. If you didn’t add them to your chart

17. FusionFission Occurs when the nucleus of an atom is split; the mass of the products is LESS Loss of mass converted to ENERGY Energy can be used to generate large amounts of energy for power plants/ atomic explosions Huge amounts of radiation and nuclear waste Many nuclear power plants use fission to produce energy The nuclei from isotopes with low weights combine to create heavier isotopes Mass is converted to ENERGY Requires high heat The sun is a product of ongoing fusion reaction Very exothermic and have capability of producing a lot of energy No radioactive byproducts Hydrogen bombs produced by fusion

23. Nuclear Reactors Devices in which controlled fission of radioactive materials produces new radioactive substances (Waste) and energy.

24. Radiation in Medicine Several radioactive elements can both cause and treat some forms of cancer through contact.

25. Radiation in Medicine Radioactive “tracers” or labels can be attached to some molecules and used to determine how a reaction works or the atoms move during research and to test for certain diseases.

26. Sterilization Radiation can be used to destroy seeds and kill bacteria on food (meat, strawberries, etc...) “Food Irradiation” recently became legal to use in the US…
