Science Experiments

Today our science experiment was all about Fizz Balloons. 

We needed:
•baking soda
•a balloon
•a plastic bottle
•some vinegar

1. Pour 3 to 5cm of vinegar into a plastic bottle.
2. Use a funnel and add about 2 tablespoons of baking soda to the vinegar.
3.Quickly place the neck of the balloon over the end of the bottle.
4. Watch wha happens.

Why is this happening:
Baking soda is a substance called a base. Vinegar is a substance called an acid. When bases and acids combine they create new substance. In this experiment carbon dioxide is created. Carbon dioxide is a gas; the gas leaves the bottle and blows up the balloon.

Here is our video to show you.

  1. Room 13 it looks like you had as much fun as Room 12 had completing this experiment. I am sure you weren't as noisy as Room 12 was though when they did the same experiment.
