Summary

As a High School Math student, I often wonder how things we learn in our textbooks relate to the "real world". That is why I created my Bell Curve Experiment. Students place a number of 6mm BBs and see where they land. After the experiment is over the students will discover that most of the spheres will tend to land in the center slots while a few outliers land in the outer boxes.

Glue each part of the stand like so...

How I Designed This

I made a sketch of the base and then extruded it.
I saved time making the posts by using a Linear Pattern Tool.

Project

Objectives
To show students how a bell shaped curve relates to the real world.

Audiences
K-12
Preparation
None
Steps
Drop BBs in the top slot

Results
Students will learn that although where each ball goes is random, most of them will fall more or less in the middle and a few outliers will land on the two outside boxes.
