Electric Light and Switch

In this lesson, teachers will guide students through the process of understanding electricity and switches using Snap Circuits. Students will learn about the function of a switch, assemble a base grid, insert batteries, and place various components including a battery holder, wire block, lamp block, and switch block. The lesson concludes with students lighting up their assembled circuit.

    1 - Introduction to Electric Light and Switch

    Welcome to our exciting lesson on 'Electric Light and Switch'! Today, we are going to learn about how electricity works and how we can control it using a slide switch. We will be using a fun and interactive tool called Snap Circuits to help us understand these concepts better.

    Start the lesson by explaining to your students what electricity is. You can say, 'Electricity is a type of energy that can produce light, heat, or power machines. We use it every day to light up our homes, charge our phones, and even cook our food!'

    Next, introduce the concept of a switch. You can say, 'A switch is a device that allows us to control electricity. When we turn on a light switch, we allow electricity to flow and light up the bulb. When we turn it off, we stop the electricity and the light goes out.'

    Finally, introduce the Snap Circuits. You can say, 'Today, we are going to use a tool called Snap Circuits to build our own electric light and switch. Snap Circuits are easy to use and safe for us to explore how electricity works.'

    Our goal is to understand how electricity can be controlled to light up a bulb using a switch. 
    Due to the age of the students and the 'toy' nature of Snap Circuits with all the parts, students will naturally deviate off the path of this lesson and will want to explore all the fun and interesting parts of the Snap Circuits set.

    Try and keep them on track as much as possible and maybe offer them a reward of some time to explore and play at the end, if they get the circuit in the lesson made.

    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.

    To explain the grid to your students, you can say it's like a map. The letters A-G are like streets running up and down (vertical), and the numbers 1-10 are like roads running side to side (horizontal). So, to find C4, they need to find the 'street' C and the 'road' 4, where they meet is where the battery holder goes.


    5 - Place wire block (3)

    Now let's put in the number 3 wire. Instruct your students to find the number 3 wire block. They need to connect one end of the wire block to the point C2 on the grid and the other end to E2. Make sure the wire block snaps into place securely.

    Explain to your students that the wire block is like a road that allows electricity to travel from the battery holder to the lamp (once we have all the blocks in place).
