Unit 4.1: Electricity

Objectives

• In Lesson 3.1, students explore the basic components of electrical circuits and model them through a hands-on introduction. They then explore the basic elements of electricity and electrical circuits and build simple circuits with breadboards and online simulations. Students collect data to derive the formula for Ohm’s Law then apply their understanding of Ohm’s Law to solve problems. They then move into a comparison between series and parallel circuits and explore their similarities and differences. Students continue hands-on breadboarding and simulations to derive Kirchhoff’s voltage and current laws. They end the lesson with a final project that applies all the skills acquired to design and build their own functional safe.

Classroom Activities

1. Prayer
2. Student Surveys
3. Continue with you KiCad Work
4. Your Engineering notebook should contain already a description of your "product" and an improved picture of what your would look like (not the circuit diagram).
   1. A description of you product (a paragraph) with a good clean drawing (not the circuit)
   2. You will need to have a Bill of Materials (BOM).
   3. The Schematic (from KiCAD) and words that explain the circuit (about a page).
   4. The PCB (from KiCAD). Will demo how to do this on Wednesday.
5. See Instruction to convert schematic to PCB
