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.
