Fusion energy Introduction to fusion Nuclear fusion is one of the most promising options for generating large amounts of carbon-free energy in the future. Fusion is the process that heats the Sun and all other stars, where atomic nuclei collide together and release energy in the form of neutrons, see diagram on the right. Fusion scientists and engineers are developing the technology to use this process in tomorrow's power stations.
In nuclear processes, atoms are not conserved, but the total number of protons plus neutrons is conserved. Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion and radioactive decay.
This lesson is the second of two Day 1: Students will elaborate on this information by learning how to determine serial decay products in a decay series. Students will apply Science and Engineering Practice 4, Analyzing and interpreting data, by graphing a series of nuclear decays and determining how atomic number and mass change.
Evidence is obtained when students see that energy in the form of gamma radiation can be emitted during decay. The questions are below in italics, answers are in bold. As they are answering these problems I walk around with a roster and check in their homework student work.
While am doing this I have the first page of the answer key on the doc cam so they check their answers after the bell ringer. After checking in the homework I will put the second page up and answer any questions.
I try not to spend too much time on this because they will have more opportunity to practice after they receive notes. Some students struggle with the back side where they have to identify what type of decay is occurring in a decay series.
This is the first time they have seen a decay series, so they are a little uncertain what was expected of them. Upon seeing the answer key it made sense what they need to do. After teaching the lesson a simple explanation would alleviate any uncertainty. Nuclear Chemistry Notes Sheet Explain 25 minutes An important part of the 5E model is getting a formal explanation that helps clarify any difficulties they are having.
I also use the note sheet because it provides them with a picture that illustrate how radiation penetrates. Powerpoint slides As I show each slide I read the slide and explain what they are seeing. Is a summary of chemical reactions compared to a nuclear reaction, definition of radioactivity and a list of the 3 types of radiation.
Summarizes stability and how as elements get heavier the neutron begin to out number protons causing the nucleus to become unstable radioactive Slides Summarize each type of radiation with a description of the particle, what it symbol is, a picture to illustrate the particle being emitted from the nucleus and how far it can travel.
Illustrates what a nuclear equation looks like. Students can use this as reference. This slide is a review of the nuclear symbol that reinforces the proper isotope notation using uranium Slide 9: This shows students how to write alpha, beta and gamma decay of uranium and thorium This is important because it provides them with a visual of each decay and how the daughter product of one decay undergoes another decay.
Is a small decay series that illustrates how the daughter product of one decay can decay into another isotope and so on till a stable atom is formed. I chose a simple decay series because they will have a chance to create one in the homework.
Is a picture showing the three types of radiation alpha, beta and gamma being penetrated and blocked by paper, aluminum foil and lead. Summarizes each particle emission in a table format. The table goes one step further than what they have learned from the previous lesson which provides new information about penetration, protection needed to block radiation and the relative danger of each particle.
This information will be explored during the next lesson when students elaborate on nuclear decay using a Geiger counter and various radiation sources to determine penetration and protection.
After completing the Powerpoint students can use the notes to complete the homework.Nuclear energy is the energy that comes from the core or the nucleus of an atom.
The bonds which hold the atoms together contain a massive amount of energy.
This energy must be released in order to make electricity. This energy can be freed in two ways: nuclear fission and nuclear fusion. Called nuclear fusion, it is the process which powers the sun and all other stars in the universe.

Nuclear fusion is a nuclear reaction in which two or more atomic nuclei (e.g. D+T) collide at a very high energy and fuse together.
