Lesson

Squishy Circuits

Lesson Overview

Upon completing this lesson the students will:

• Develop models to illustrate and explain that energy can be transferred from place to place by electric currents and that electric currents flowing through a simple circuit can be used to produce light;

• Understand the difference between series, and parallel circuits;

• Construct explanations of how some materials allow electricity to flow through a circuit and some do not; and

• Understand the difference between conductive material and insulating material.
