Grade 5 Science Experiment 4 - "Vinegar and Baking Soda, the chemical secret behind a Fire Extinguisher"
OR
Purpose:
The purpose of this science fair project is to create your own fire extinguisher. The chemical process behind a fire extinguisher will be demonstrated, explored, and discussed. A fire extinguisher used in the past was made without the aid of air compression. Instead, a fire extinguisher had to reactive chemical agents. The chemical agents were vinegar and baking soda. When you combine vinegar and baking soda, carbon dioxide foam is produced. Carbon dioxide foam puts a fire out by replacing the presence of oxygen. (A fire needs oxygen in order to continue burning.)
Hypothesis:
Carbon dioxide foam can be produced when you combine the two chemically reactive agents of vinegar and baking soda.
Variables:
Time it takes the vinegar and baking soda to produce carbon dioxide gas and foam
Materials Needed:
- 16.0 fluid ounce plastic bottle that has a screw cap
- Fork
- Scissors
- Paper clip
- Teaspoon
- Tea bag
- Vinegar
- Baking soda
- Drill
