This experiment will show you how to make a water electrolysis science model for your science project. Water is one of the most valuable compounds found on Earth. Water is made up of two hydrogen atoms bounded by one oxygen atom.

Electrolysis is a process by which water can be broken down into its (hydrogen and oxygen) components.


We will make this water electrolysis model using materials easily available at home.


  • Two sharpened pencils ( both sides)
  • Plastic container
  • Copper wire
  • Salt
  • Battery
  • Water (regular)

Steps To Make Water Electrolysis Science Model

Step 1: Firstly, take a container full of water and add some pinch of salt. After that fix two sharpened pencils (both sides) in small-sized cardboard.

Step 2: Immerse pencils into the water and ensure that the tips of pencils don’t touch each other.

Step 3: Connect the positive terminal and negative terminal to pencils. Then, connect them with the battery.

with the battery

Step 4: This process quickly creates bubbles at the pencil tip in the water. Finally shows that it is working properly.

Electrolysis Of Water Experiment Working Model

Electron energy here breaks down water into its ions. The above experiment is an “electrolysis experiment.”

Positively charged hydrogen ions meet at negative pencil and result in hydrogen gas that bubbles to the surface“.

Negative charges meet at the positive pencil tip and result in the formation of oxygen gas.”


The Water Electrolysis science model can be helpful for students and kids to visualize the hydrogen and oxygen component present in the water by bypassing the current through water.

Things To Remember

  • Working slowly and carefully during battery and water.
  • Learn all you can about the materials and techniques you’re using.
  • Work carefully during wire attachment.
