Count Pine Cone Scales
- Gather pine cones from outside your school with your students, or bring some in from home. You should try to get both male and female cones. Male cones: generally smaller, with scales closed up. Females cones: larger, open scales, often seeds are visible or seed pockets.
- Have your students estimate the number of scales on both kinds of pine cones.
- They should then actually count several of each and come up with an average. Have a large recording sheet available at the center where students can record their final averages.
- When all students have finished, you can get the class average using the totals.
