Science Experiments

 Our Science Experiment

We did a cool experiment last Friday. 

First, we had two containers. One is filled with ice and the other one is filled with hot water.

We placed a bottle with a balloon in it. 

Then, we gathered data:

Experiment 1

7 said the balloon will expand if we put it on the container with ice.

3 said it will explode.

5 said nothing will happen to the balloon.

Experiment 2

2 said the balloon will fly away.

10 said the balloon will expand.

The balloon expanded with the hot water but nothing happened to the balloon in the ice container.

We learned the cold air goes down and warm air goes up. That is why the balloon in the hot water container expanded.

We also tried putting the balloon bottle in a bigger container of hot water to see if it will expand more. And it did!

Some wanted to try and put hot water inside the bottle. The balloon did not expand.
