Making Simple Paper Circuits

Today in Grade 2 we tried to answer a student question:

"How does a battery light up a light?"

We did this by exploring simple circuits. The students used copper tape, sticker LEDs and a button battery.  First we had a talk about batteries. The students were given a button battery to try to find the positive and negative sides.

We made a connection to how we use batteries in our toys. The students had a lot to say about how important it is to get the + and the - the correct way around. Next we used a template. This can make it easier for beginners as this was our first time to make a circuit. We used copper tape for the wires.

The copper tape can be bought online or at a hardware shop. It is best to use narrow tape for beginners as it will go around a corner more easily. If it is a young child, be aware that the edges of the tape are sharp and can cause a paper cut.

I made a quick circuit diagram as these learners are beginners. It was easily photocopied and all the students had to do was follow the lines for the tape. You need to note that the lines between the battery and one side of the LED must be strong and continuous. At the LED there is a break. Make sure that there is a little break here at that part between the positive and negative sides.

Put the sticker LED on after you have put down the copper tape.You can add extra copper tape on top if you need to make a stronger connection.

Once your circuit is complete you can add the battery to test your light. If it is not working, add some extra copper tape on the corners and either side of the LED light to help make your circuit stronger.

Here is a video of a finished circuit. The students added a drawing on top which featured a light to light up using their circuit.
