Science Fair Projects for 7th Grade

These science fair projects for 7th grade are perfect for allowing older kids to explore more advanced scientific concepts, like electrolysis and electroplating.

Copper Plated Coins

Use some household materials to plate your coins with copper! You can also try copper plating designs onto your coins!

Electrolysis is a way to dissolve bits of metal into acidic liquids like vinegar. When you run electricity through vinegar, the vinegar helps to carry electricity from one side of the circuit to the other. Electroplating is a way to put those little bits of copper onto something else. With just a little electricity, you can use electrolysis and electroplating to plate a quarter with copper. Does that make it look like a penny to you?
