Chemistry experiments for kids are a great way for parents to spend quality time with their children, have fun, and learn something all at the same time! Remember than running and rationalizing experiments is one of they cornerstones of learning science.
Here are a couple of fun chemistry experiments that your kids are sure to love.
Chemical Reaction Experiments for Kids: Green Pennies and Copper-Plated Nails
This awesome experiment is really three chemistry experiments for kids in one! First, in Part 1, an acid-base reaction gives dull pennies their original shine back. Then, in Part 2, we use redox chemistry to turn some of those pennies green. Finally, in Part 3, we coat ordinary steel nails in copper.
What you’ll need:
- About 20 dull pennies
- A shallow bowl (glass or plastic only)
- ¼ cup white vinegar
- 1 teaspoon salt
- A couple of clean steel nails
- Water
- Paper towels
Part 1: Making Dull Pennies Look Shiny and New
- Combine the vinegar and salt in the bowl and stir to dissolve the salt.
- Start by dipping a penny halfway into the vinegar solution and holding it there for 20 seconds. Make a note of what you see.
- Dump the remaining pennies into the bowl and leave them there for 5 minutes.
- Your pennies should be bright and shiny again! Reserve the solution for Part 3.
