My son loves science kits. We recently built a battery operated domino robot from a kit. After observing his interest, I decided to research robots that could be made with homemade materials. As a result, we found an easy electric circuit experiment for kids.
We decided to start with a simple circuit project, where we lit a LED light bulb using batteries. Surprisingly, it was easy to do. However, parents need to be present when their children are doing this experiment.
