This is activity is a really fun way for your student to learn about circuits and conductivity. The materials are not something that most have on hand, such as LEDs and motors. There is a direct link provided to purchase the supplies you need, but you can actually look up recipes to make your own conductive and insulator dough at home. You would, however end up having to use up flour which is a bit of a scarce resource now. Overall very engaging if you are actually able to obtain the supplies.
