Bell Shaped Curve Demonstration

thingiverse

As a High School Math student, I often ponder how things we study in our textbooks connect to the "real world". That's why I developed my Bell Curve Experiment. Students place several 6mm BBs in the top slot and see where they land. After the experiment is over, students will discover that most of the spheres tend to land in the center slots while a few outliers fall into the outer boxes. Print Settings Printer: Printrbot Play Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: Does not Matter Infill: 20% Post-Printing Glue each part of the stand together as shown... How I Designed This I sketched out a design for the base and then extruded it. I saved time creating the posts by using a Linear Pattern Tool. Custom Section Project Objectives To demonstrate to 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.
