1 STARTER: WATCH THE VIDEO CLIP https://www. youtube. com/watch Video Questions:What has this got to do with today's lesson?What had batman designed in his basement to aim to save Gotham city?What was the truck carrying around in the video clip?What did the baddie (Baine) try and turn the nuclear fusion reactor into?
2 TITLE: Nuclear Fission vs Fusion Objectives (We are learning that):Nuclear fission is used in nuclear power stationsNuclear fusion takes place in the SunKEY WORDS:FissionFusionReactorChainSunTemperatureNeutronabsorbOutcomes:You should be able to...Using the slides create a revision A3 poster to summarise nuclear fission and nuclear fusion.Cut images and sentences from the PowerPoint to create it.Research images using the internet and watch video clips
3 P2 – Physics – Nuclear Fission Nuclear fission is the splitting of atomic nuclei and is used in nuclear reactors as a source of heat energy which can be transformed into electrical energyThere are two fissionable substances in common use in nuclear reactors:Uranium 235Plutonium 239https://www.youtube.com/watch?v=D91T-B-PVE0
4 P2 – Physics - Nuclear fission More neutronsNeutronUranium or plutonium nucleusUnstable nucleusNew nuclei (e.g. barium and krypton)
5 P2 – Physics - Nuclear Fission - Chain reactions Each fission reaction releases neutrons that are used in further reactions.
6 P2 – Physics – Nuclear Fusion Nuclear fusion is the joining of two atomic nuclei to form a larger oneNuclear fusion is the process by which energy is released in starsFind an image to show nuclear fusionhttps://www.youtube.com/watch?v=Cb8NX3HiS4U
