Carbon dioxide

Carbon dioxide is a greenhouse gas, and is trapping heat from the sun in the Earth’s atmosphere. Carbon dioxide has a big part to play in Climate Change, so we did a few experiments about carbon dioxide. 

We mixed vinegar and baking soda to create a chemical reaction. The vinegar and baking soda fizz and hiss, and together create carbon dioxide.

When we mixed vinegar and baking soda in a bottle, and put a balloon on the top of the bottle, it inflated the balloon with carbon dioxide! Have a look at our experiment.


We also used carbon dioxide to put out a lit match, and to put out a candle. Carbon dioxide is used in fire extinguishers to put out fires as well. Below are YouTube videos of experiments similar to the ones we did.
