What Things Rust Easy Science Experiment
In this fun and simple science experiment we are going to explore rust and try to identify what things rust. This is an easy yet very interesting experiment that can be adapted to make an awesome science fair project.
- Small clear plastic cups
- Notebook and pencil
- Various metal objects from around your home. Nails, screws, washers, paper clips, staples, bobby pins and safety pins are a few examples of items you can easily find and use in this experiment to determine what things rust.
- Make sure you have one clear plastic cup for each metal item.
- Fill each cup about halfway with water.
- Drop one of your metal objects into each cup.
- Make a list of the items in your notebook.
- Check on the items one time a day for seven days and notice any observable changes.
- Log your daily observations in your notebook.
How it Works:
Rust forms when iron metal comes in contact with oxygen which causes a chemical reaction called oxidation. Rust is the reddish brown substance called iron oxide that is the result of this chemical reaction. The oxygen in water helps facilitate this process and allows you to identify which items rust.
Make This A Science Project:
This is a great experiment that lends itself well to easily become a science fair project. You can use various metal items to see which ones rust. You can put items in the fridge to see if different temperatures effect the rate at which things rust. You can also test and see if adding salt to water causes any observable changes. Test filtered water, tap water, distilled water, and other liquids to see if there are different rates at which your metal items rust.
