Chemical Reactions

For our Science experiment this week, we are going to make a Carbon Dioxide Fire Extinguisher.

What is a chemical reaction?

Today I will add 2 substances together. There will be a chemical reaction and Carbon Dioxide will be produced.

I will add baking soda to vinegar, a chemical reaction will take place and carbon dioxide will be produced.

What 3 elements are needed for fire?

Take away any one of these elements and the fire extinguishes.

To make our fire extinguisher, we will make Carbon Dioxide with a chemical reaction between vinegar and baking soda.

When the carbon dioxide gas is produced we will pour it out of the jug. But won’t the carbon dioxide float off into the air.

Because carbon dioxide is heavier than oxygen the carbon dioxide gas will flow downwards out of the jug and onto the candle and quench it.
