Balloon Experiment

When talking about Push and Pull in science I remembered this fun balloon experiment.

One of our favorite activities was to see if our fan could push several classroom objects.

We tried a wooden block, cotton balls, super balls and balloons.

We measured and discussed how far each object moved along the floor, or didn't move, and why we saw these results.

For example, we decided that the cotton ball wasn't moving as much as we thought because it appeared to be "velcro-ing" to the carpet.

The children were also coming up with ideas on how to modify the balloon experiment and one student said, "What if we aim the fan straight up? What would happen?"

Well, we tried it and I don't think any of us expected the result we received...

The balloon hovered in mid-air. It didn't fall, it didn't blow away, it just spun in place!

We left it there for the rest of the day. It was still hovering when we got back the next morning. And, I'm quite sure it's still floating there still.

This experiment filtered into Writer's Workshop. We were working on the craft of poetry writing, so we wrote poems about the balloon.

We used many of the poems in The New Kid on the Block as models for writing. If you can only afford one poetry book, I just adore anything by Jack Prelutsky.
