All About Rust Experiment
Description: This scientific experiment for children demonstrates that the chemical iron, in the presence of
water “oxidizes” and forms iron oxide, or rust. This explains why old cars rarely have rust in dry climates
and often have rust in wet climates.
Goals: To demonstrate that steel oxidizes in the presence of water and forms iron oxide or rust.
Objectives:
1. Learn the observation and chart method to notice changes in an experiment.
2. Learn to compare the appearance of the steel wool from the first day to the final day.
3. Learn to identify rust on metal.
Materials:




Steel wool
Paper and pencil
Water
Shallow pan
Procedure:
1. Pour water into the pan until it is about one inch deep.
2. Place the steel wool in the water.
3. Make a chart with days one to five down the left side and the heading "What the steel wool looks
like" on the right side of your paper.
4. Each day, describe the appearance of the steel wool on your chart. Can you explain the changes?
