This project demonstrates the electroplating process using a copper sulfate solution. By connecting a power source, students will coat different objects with copper, exploring principles of electrochemistry.
Applying an electric current will cause copper ions to deposit onto the object, creating a layer of copper.

Put on safety goggles and gloves.
Prepare the copper sulfate solution in a beaker.
Connect the metal object to the positive terminal of the battery.
Use copper wire as a cathode and connect it to the negative terminal.
Submerge both the metal object and copper wire in the solution.
Turn on the power source.
Observe the electroplating process over 30 minutes.
Remove the object, rinse it with water, and dry.
Record observations and measure the thickness of the copper layer.
Repeat with different objects to compare results.
The metal object will be coated with a layer of copper, demonstrating the electroplating process.
