Students in Mr. Oliver's class were trying to find out if a large pumpkin had any correlation to a large number of seeds. The students first predicted the weight each pumpkin. Then, they took the pumpkin to weigh it. They wrote the weight of the pumpkin on the front. They then took the seeds out of the pumpkin and counting them. They recorded their answers on a spreadsheet.
I would like to teach first or second grade, so I don't think I would modify this too much. I really like the idea. It would be very cute for Halloween. It also helps teach the important concept of estimation. In my math class we were discussing how many students don't have the background of estimation before being taught how to measure. The had a couple case studies that said it was easier for students to figure out all types of measurements if they had some estimation skills. This allows to students to have a partial understanding of what they're working with. I also like that the project lets students interact with the work. They can get their hands dirty and still learn at the same time. This kind of activity could also be used for liquid measurements, or also things like feet and inches.
