How many seeds? (K – 8)

What you’ll need:

1 pumpkin

Knife

Large Spoon

Newspaper

Disposable gloves (optional)

What to do:

Cut open the pumpkin, removing the top.

Separate your students in to small groups. Have each group of student’s estimate how many seeds are in the pumpkin.

Scoop the seeds out and give a pile to each group. Then each group counts the seeds.

Add the individual group totals together.

Whose estimate is the closest to the actual number? How far off is the best estimate?

Discuss the findings.

Additional research:

Take another pumpkin that is ether larger or smaller than the original one. Have the group’s estimate how many seeds are in the new pumpkin based of previous findings and on the new pumpkins size.

Again remove the seeds and give to the groups to count.

Add the group’s totals.

Whose estimate is the closest? How far off is the best estimate? Does the size of the pumpkin effect how many seeds are inside?

Discuss the findings.
