More Air Investigations!

We have been busy in Room 311 continuing to investigate air and learning more about Weather.

First we explored this...

All groups concluded that yes, indeed we could move the air in the balloon if we applied a force to it like squeezing the outside of the balloon or moving the balloon back and forth.

Next up was Balloon Rockets!



First we had to blow up a balloon and secure it with a rubber band.




Then we taped a straw on top of the balloon and put a string through the straw.



We wanted to investigate what would happen when we let the air out of the balloon.

It moved!

Some of our balloon rockets worked better than others, but that gave us a great lesson as scientists. We had to think about changes we would make to our design just like real scientists have to do all the time.
