This is the second part in a series of classes designed to introduce learners to particle physics. In part 1 I introduced learners to the Standard Model of Particle Physics and helped learners understand the matter and forces that cause everything in our universe to exist. In this class, part 2, we will explore the properties of particles, as well as how particles interact using the different forces. Properties discussed will include spin, mass, electromagnetic (QED), and chromatic (QCD). ...
10 lessons//10 Weeks
Week 1Lesson 1Review of Standard Model~ Review the Standard Model of Particle Physics (from Part 1) ~ Learn the quantum meaning of applying forceWeek 2Lesson 2Electromagnetic Force (QED)~ Understand the quantum reasons for attraction and repulsion between electric charges ~ Listen as I describe the properties of photons and why they only impact certain particlesWeek 3Lesson 3QED Reactions Between Particles~ Understand what Feynman diagrams are and how they show reactions between particles ~ Sketch several Feynman diagrams and be able to explain the reactions they represent ~ Learn about virtual particles, how they act, and their presence in Feynman diagramsWeek 4Lesson 4Strong Nuclear Force (QCD)~ Understand the basics of how the strong force, which is called quantum chromodynamics (qcd) ~ Listen as I explain the development of qcd and how we now understand the strong nuclear force ~ Sketch examples of protons and neutrons that have accurate quarks and include the correct qcd (also called color charge)Week 5Lesson 5QCD Reactions Between Particles~ Strong force-carrying gluons (types of color charge they can carry) ~ Quarks change color through gluon exchange ~ Sketch Feynman diagrams to show the ways quarks and gluons carry and/or change their color chargeWeek 6Lesson 6Spin Property of Particles~ Listen and ask/answer questions about the spin property of particles ~ Sketch a model of the experiment that proved that particles have spin ~ Learn the spin of the particles in the Standard ModelWeek 7Lesson 7Mass Property of Particles~ Understand the relationship between mass and energy ~ Learn the mass of the particles in the Standard Model ~ Understand how probability helps us understand mass of particlesWeek 8Lesson 8Weak Nuclear Force and Particle Decay~ Understand how particles decay through the weak force ~ Sketch sample Feynman diagrams showing particle decay ~ Predict further decaysWeek 9Lesson 9Weak Nuclear Force and Radiation~ Understand that beta radiation in atoms is caused by the weak force ~ Sketch example of how an atom decays and explain the result of the decay (radioactivity) ~ Use what you learn to explain why some elements are radioactive and others are notWeek 10Lesson 10Gravitational Force and its Unknowns in Particle Physics~ Learn specific details about why gravity works ~ Understand the difference between gravity at the particle level and gravity at our level ~ Understand why we haven't yet found an elementary particle of gravity
- Learners will understand that all things happening in the universe are caused by particles and their interactions. They will be able to explain and describe elementary particle interactions after completing this class.
I have been teaching homeschoolers ages 6-21 for 18+ years. During that time I've taught all traditional subjects and found ways to tailor them to the needs and learning styles of all learners. I have taught math, chemistry, and physics on Outschool for 3 years. I have studied particle physics in the past and continue to attend particle physics lectures to broaden my base knowledge and help me teach the most up-to-date material possible in this changing field. During my time teaching I've had many learners ask about the subatomic world and what we know about it, which has helped me create strategies in teaching this content.
Completion of The Universe at the Smallest Level: Understand the Building Blocks (Part 1 of 3) OR previous experience with the Standard Model of Particle Physics.
A notebook dedicated to this subject is preferred, but not required. We will reference material from previous lessons so it will be helpful to have previous notes.
