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. Write a one page document of a circuit that uses a Solenoid
3. It must contain a description and a diagram. The diagram must be neat and use drawing tools that come with your editor. The drawing is not a circuit, but what it functionally would do and look like.
4. The circuit must contain at least one LED and one switch
5. Be imaginative! Ultimately we will build this project you describe. If it is too simple, it will be returned.
6. You will breadboard your design and ultimately we will try to create a PCB for the circuit.
7. It will be connected to a 9V battery and use a voltage regulator to bring the voltage down to drive digital circuits.
8. See Fun With Digital Electronics
9. Print out your one page and bring it to next class.

Homework

• Print your one pager and bring it to class.
