Sketch Circuits and Explore LEDs and Resistors with Two New Lessons

circuit sketching components
Thursday, December 14, 2017

Introduce students to fundamental electrical engineering concepts with two new free lesson plans.

Sketching Circuits - Expanding on understanding of simple circuits, this lesson explores conductivity and introduces students to the new technique of drawing electrical pathways for circuitry with pens. Students will design, and build a simple circuit using drawn connectors and construct a device for testing materials for conductivity.

LEDs and Resistors -  This lesson explores LEDs and resistors and reviews the differences between parallel and series circuit design and functions. The  activity encourages students to build a simple circuit on breadboard using simple electrical components including LEDs and resistors. Students work in teams to predict and test how different resistors impact LED brightness. After testing several predictions about each circuit type, the groups will compare results and discuss findings. Advanced students may also explore and test on the breadboard how arranging LEDs in parallel and series impact brightness.

TryEngineering.org. lessons encourage problem solving, critical thinking and team building skills. Each lesson includes step-by-step instructions, a list of low-cost materials, background information, and student worksheets. All lesson plans are aligned to national education standards including the Next Generation Science Standards, ITEEA Standards for Technological Literacy and Common Core Mathematics Standards where applicable.
