It is that time of year again. The leaves are changing colors, the air is crisp and giant pumpkin guessing contests are in full swing. I was wondering if there is a formula that could be used to estimate the weight of a giant pumpkin. How could you use this concept in a math lesson or review? What better way to provide students with a real world example of how to use math skills to win prizes!
Depending on what age of students you have, I think this would be a great activity for the students to solve on their own! The teacher could bring in a variety of pumpkins, some scales and tape measures, and see if the students can find their own formula!
I was thinking about a similar thing yesterday. You know that contests where you have to guess the number of jelly beans/pennies/etc. in a jar? Well, what about a "blind" contest for Halloween where kids have to guess the number of seeds in a pumpkin? But they have to guess BEFORE the pumpkin is cut open. They could do some research by looking at some smaller pumpkins, and then extrapolating to make an estimate. (I was shocked to learn that the pumpkin we bought this year had 566 seeds!)
