Conduction

In this lesson, you'll guide students through building a circuit and testing various objects and materials for electrical conduction. Students will assemble a circuit using a base grid, batteries, a battery holder, a red LED light block, a resistor block, and wire blocks. They'll then experiment with different objects to identify conductors and insulators. The lesson concludes with a review and disassembly of the circuit.

    1 - Introduction

    Today, we are going to learn about conduction. 

    Explain to your students that today we will be making a circuit with the red LED light and then testing different objects and materials to see if they conduct electricity.

    Our goal today is to understand the concept of electrical conduction and identify materials that can conduct electricity.

    2 - Prepare the Base Grid

    Instruct your students to place the base grid on a flat, stable surface. Make sure each group has enough space to work comfortably. This is an important step to ensure the stability of the snap circuits they will build.



    3 - Inserting Batteries

    At this stage, we need to ensure that the batteries are in the battery holder. If they are not already there, please insert them now. Each Snap Circuits set you are using will need its own set of batteries. So, if you are using multiple sets, make sure each one has its batteries properly inserted in the battery holder. This is crucial for the functioning of the circuits we will be building.


    4 - Place the battery holder (B1)

    Now, let's place the battery holder on our base grid. Tell your students to find the spot marked as C4 on the grid, this is where we will place the battery holder (B1).

    Once they have placed the battery holder correctly, they should press it gently to snap it into place.



    5 - Place the red LED light block (D1)

    Now, it's time to add the red LED light block (D1) to our circuit. Instruct your students to find the red LED light block (D1). This block should be placed on the grid (F2 to F4).

    It's very important that they place the positive + and negative - sides of the red LED light block (D1) correctly as shown, as the electricity needs to flow the correct way. The + side of the red LED light block (D1) should connect to F2 and the other side to F4.

    If it's placed the incorrect way, the LED light will not light up.
