Our whole class had a zoom and a blast day!
We did some experiments and discovered how to make a rocket. We got a cannister and filled it with vinegar.Then we filled the lid of the cannister with bicarb soda.
After that we immediately placed the lid back onto the cannister and turned the whole thing upside down. When the soda and the vinegar mixed together, it made a chemical reaction and started fizzing and then… then…
IT POPPED!
This is because a gas called carbon dioxide was made. The pressure of the gas made the cannister pop away from the lid. And that is how to make a rocket blast off.
Tune in for more!
Some people got splattered with the vinegar and bicarb soda. Yuck!
BLAST EACH OTHER AWAY!
This post is about another experiment our class did.
It was about blowing up a balloon to it’s limit.
We had to fill up a bottle with vinegar and then we placed some bicarb soda in a balloon.
Next we placed the balloon on top of the bottle and watched what was about to happen.
We hypothesized that the mixing of the vinegar and the bicarb soda would cause a chemical reaction to happen. This chemical reaction would make Carbon dioxide which is a gas.
The gas would build up inside the bottle, go into the balloon and blow up the balloon!
Our hypothesis was correct!
The balloon actually blew up to it’s limit!
Wow! It was a scientific procedural success!!
