Math & Science Pumpkins – Activity 1

Categories: Agriculture , Math & Measurements , Plants

Pumpkins are a great manipulative for math and science exploration. These activities are ideal to follow up field trips and make the most of the natural connections between pumpkins and math and science.

INSTRUCTIONS

  • Divide your class into groups of 3-4 students. Provide each group with a pumpkin. (Pumpkins should be quite different from one another.)
  • Ask students to look around at the other pumpkins and predict which group has the largest pumpkin. Which one do they think weighs the most? Do they think the largest pumpkin will weigh the most? Will the smallest weigh the least?
  • Students should record their predictions. These predictions and actual measurements can be recorded on a class-wide graph.
  • Students then weigh the pumpkins and compare findings with prediction.
  • Consider: Weigh one pumpkin in front of the class before the students make predictions about their group’s pumpkin. This base knowledge can change predictions into estimations.
