P5/6 Made Carbon Dioxide

P5/6 A made carbon Dioxide today.

In groups we measured vinegar into a bottle and placed baking soda into a balloon. We then placed the balloon carefully onto the top of the bottle. When we tipped the powder into the vinegar, it fizzed rapidly, and made CO2. The balloon inflated and we measured it’s circumference.

We then filled another balloon with a similar amount of air and dropped them both from a height. Mrs Abraham helped us up one at a time in each group to test our balloons.

We found out which gas was heavier, carbon dioxide or air, what do you think?
