Click on the NUCLEAR FISSION banner and the NUCLEAR FUSION banner below to watch the YouTube videos on Nuclear Fission and Fusion. While watching the videos, write down the answers to the questions on the right side of the link. The answers to the questions from each of the 3 sections of the unit will account for 70% of your unit grade. When you complete each section, submit your answers via the link below. The link will send you to a Google Forms document where you will input your answers to the section's questions. Unit assessments will be released on Thursdays. After you have submitted your answers for each of the 3 sections AND the unit assessment, you will receive a grade for the unit.
Your answers to the questions below need to be manually submitted via a Google Forms document, using the link (button) on the right.
Nuclear Fission is the splitting up of large and unstable ______________ into smaller nuclei, releasing lots of energy.
Nuclear Fission can occur in two different ways; ______________, where fission is unforced and happens by itself and by absorbing a ______________ which can split a nucleus making it even less stable.
In a nuclear reactor the fission process is started with a Uranium 235 isotope and forcing a neutron into its nuclei, making it even less stable. The Uranium 235 isotope splits apart into two “daughter” nuclei, 2 neutrons and lots of energy in the form of ______________.
The fission process needs to be very carefully controlled. The neutrons released from the decay of Uranium 235, interact with other Uranium 235 isotopes, causing a massive ______________ ______________ which releases even more energy. If left uncontrolled, this process is the basis for the explosion created by a Nuclear Bomb.
Generating electricity from Nuclear Fission, involves the radiation heating up water and turning it into steam. The steam drives large ______________, generating usable electricity.
Nuclear ______________ is when 2 light nuclei fuse together to form a single, larger nuclei.
The process of Nuclear Fusion tons of energy, relative to the process of Nuclear Fission, and is the process that fuels ______________.
The reason Nuclear Fusion releases so much energy is that ______________ is converted to ______________, apparent in the lighter weight of the resultant atom.
While Nuclear Fusion is an excellent source of clean energy, resulting in no radioactive waste, it is highly impractical because the reaction requires extremely high ______________ (10 million degrees Celsius) and ______________.
