Lesson Plan: Up Quarks and Down Quarks Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the properties of up and down quarks and the composition of protons and neutrons.
Objectives
Students will be able to
- recall that protons and neutrons are not fundamental particles,
- recall that protons and neutrons are made of up quarks and down quarks,
- recall that up quarks and down quarks are fundamental particles,
- recall that there are 2 up quarks and 1 down quark in a proton,
- recall that there are 2 down quarks and 1 up quark in a neutron,
- recall the symbols for up and down quarks,
- recall the relative charges of up and down quarks,
- work out the relative charge of composite particles made of up and down quarks.
Prerequisites
Students should already be familiar with
- the electric charge,
- the basic atomic structure: protons, neutrons, and electrons.
Exclusions
Students will not cover
- strange, charm, top, and bottom quarks,
- any antiquarks,
- any leptons except the electron and positron,
- decay processes,
- gluons,
- the strong nuclear force.
