Chemistry isn’t just something that happens in a lab with Bunsen burners and beakers—it’s all around us, from the food we eat to the air we breathe. You can turn your home into a mini science lab with everyday items and engage your child in the wonders of chemistry. Whether you’re looking to supplement your child’s school learning or spark a new interest, here’s how you can use common household items to teach important chemistry concepts.
Vinegar and Baking Soda: The Classic Reaction
CH3COOH(l) + NaHCO3(s) →CH3COONa(aq) + H2O(l) + CO2(g)
What You’ll Need:
- Vinegar
- Baking soda
- A bowl or bottle
What It Teaches: The reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) is a fun and safe way to introduce the concept of chemical reactions, acid-base interactions, and gas production. When these two substances mix, they create carbon dioxide gas, which can cause bubbling and fizzing. This is the same reaction that happens in some fire extinguishers!
Try This: Mix a few tablespoons of baking soda with vinegar in a bottle and watch the reaction. To take it further, quickly cover it with a balloon to catch the gas and inflate the balloon.
