Pumpkin Science … Rotting Pumpkin

We had a little pumpkin drama on the day Little M brought her pumpkin home. No need to point fingers (since the only innocent party was me).

When the pumpkin cracked, there were tears… and consequences were doled out… but then I had an idea. Why let this sad experience go to waste?

Why not turn it into a pumpkin science experiment? A rotting pumpkin science experiment, in fact! We love an opportunity for exploring the scientific method with children.

That is just what we did. I brought out our nature journal, and we made a few initial observations. We also talked about what we thought would happen to our pumpkin.

While doing this experiment, I used scientific words. We recorded our hypothesis, data, and even the conclusion.
