We read in Margaret McNamara's How Many Seeds In A Pumpkin?, that one clue to how many seeds a pumpkin will have, is the number of ribs on the outside. Apparently, each rib represents a row of seeds, inside.
The color of the pumpkin is another indicator. Darker orange pumpkins, have likely had longer to develop on the vine, and therefore might have more seeds.
I'll admit, we were intrigued. We didn't really buy into the darker orange theory, because in the past we've had to ripen pumpkins on our table, after saving them from an early frost in the garden. So, we know from experience, that pumpkins will continue to darken in shade, after they've been cut from the vine.
But, we had to check out the connections between the ribs, and the rows of seeds, ourselves. So, we took two pumpkins, one large, and one small, and counted the ribs.
We also weighed them, and measured, and recorded their circumferences, and colors, just for fun.
The larger pumpkin was a darker orange, but the smaller pumpkin had about ten more ribs, than the larger one. So, we predicted the smaller pumpkin would have more seeds. Then, we cut them open, and checked them out. Sure enough, the seeds were arranged in lines corresponding to the ribs, at least the deeper ribs, on the outside.
All, that was left to do then, was pull the seeds out, and count them. The larger pumpkin had 483 seeds (very large seeds), and the smaller one had 620 seeds (smaller, more tender seeds - good for roasting).
As, I'm sure you can imagine, we had quite a bit of pumpkin themed, math going on as well, but I'll save that for Math Monday, tomorrow.
In the meantime, as usual, you can find more fun with science, at this week's Science Sunday link-up, at Adventures in Mommydom.
It's great to be a homeschooler.
