Rust Resistant
Nobody likes rust to form on their favorite toys, so have your kids learn what chemical reaction to avoid in order to become rust resistant.
What You'll Need:
- Rubber gloves
- Scissors
- Steel wool
- 3 test tubes
- Water

How to Make Rust Resistant:
Step 1: Make sure your kids put on the rubber gloves. Have them cut three small equal-size pieces of steel wool, and place a piece into each test tube. Don't have them add anything else to test tube one.
Make sure your kids wear rubber gloves to avoid splinters when handling steel wool. |
Step 2: In test tube two, have your kids add enough water to totally cover the steel wool. In test tube three, have your children add enough water to cover half the steel wool.
Step 3: Make sure they leave the test tubes alone for a few days, and then have them observe the results.
Only the steel wool in test tube three rusted. This is because both water and oxygen are needed for this chemical reaction to occur. |
The rusting of iron is a type of chemical reaction known as oxidation. Molecules of iron combine with molecules of oxygen to form rust molecules (ferric oxide). |
