Can you split water into hydrogen and oxygen?

Hey Science Family!

I used to constantly be looking around for extra Oxygen and Hydrogen atoms, I never could find enough for my projects. Then I realized I could just take water and split it in two. Easy right?

Science is never as easy as that first idea, and I had to spend some time figuring out exactly how to do it.

Today, we’ll be learning how to break H2O into Hydrogen and Oxygen, and looking at the magical properties of one of our most common tools.

Parent Tip – You can easily fashion a battery cap for your 9V by repeatedly hotdog folding aluminum foil into thin wires, then taping them to the positive and negative ends of your battery. Just don’t let the wires touch

Thursday:  Splitting water (Physics/Chemistry)

Activity: Split water into it’s two components, hydrogen gas and oxygen gas

Sharpen up your pencils – we’ll need them as we magically split water into gas using electricity


  • 2 graphite pencils – we will sharpen both ends
  • 9V battery
  • 9V battery snap (but we can engineer around this if need be)
  • Wires (again, we can engineer around this if need be)
  • Water
  • Plastic cup
  • Plastic or cardboard to create a lid for our cup
  • Hole puncher or scissors
  • Baking soda
