Career Academy Integrated Unit Plan

Academy Name: ____Academy of Engineering__ School: ___NSBHS______

Integrated Unit Plan Title: Practical Electrical Circuits
Courses to integrate: Physics, Digital Electronics
Grade Level: 11
Timeline & Duration: 3rd Quarter
Unit Summary: The focus of this unit is to introduce students to the concept and function of electricity. This is accomplished by starting at the foundational level of atoms and electrons, then building up to concepts like voltage, current, and resistance in simple DC circuits. Students become familiar with electrons as particles, waves, and the subatomic source of static and flowing electricity. They construct DC circuits and calculate values using Ohm’s Law. They also learn about electrical power and energy and how to discuss and differentiate these quantities in real-world scenarios.
Additionally, students will learn about series and parallel circuits and how to calculate voltage, current, and resistance in each. The unit will culminate in the students designing, simulating and building a circuit that will sound an alarm when light shines on a sensor.
