Grades: 3-8 (60 minutes or 1 classroom period)
This presentation is an excellent introduction to electricity. Students first experiment with batteries and buzzers to create a simple electric circuit and learn about open and closed circuits. Then students make predictions and test circuits to discover the four ways to light a bulb using a battery, a piece of wire and a bulb. Students will then formulate a conclusion on what basic components are needed in every circuit.
Grades: 4-8 (60 minutes or 1 classroom period)
Students learn about the differences between simple, series and parallel circuits. Using batteries and light bulbs (including LEDs) to build these circuits, they discover the voltage differences between them and how that affects the brightness of the bulbs. They will also learn about the corresponding schematic diagrams for each circuit. Due to the advanced content in this lesson, we require students first experience Basic Circuits.
Grades: 4-6 (60 minutes or 1 classroom period)
This lesson is a great final circuit lesson because it snaps all the main concepts learned together. Students build 4 different circuits using Snap Circuit kits. They identify the types of circuits as well as analyze each circuit as a system to figure out how the energy is being transferred and transformed within it. The concept of switches is also introduced. Due to the advanced content in this lesson, we require students to first experience the Basic and Advanced Circuit lessons.
