# Testing the Bell Curve

Hard

Have you ever wondered if you can predict the probability of a marble falling into a certain slot? This experiment will help you find out! You'll construct a device with 12 compartments and drop marbles from a funnel at the top. The results will show if the probability of the marbles falling into each compartment follows a bell curve.

## Hypothesis

The hypothesis is that the probability of the marbles falling into each compartment will follow a bell curve.

## Method & Materials

You will construct a device with 12 compartments and drop marbles from a funnel at the top.

You will need a 1 foot X 2 foot piece of pegboard, 12 one inch slats, wooden dowels, and marbles.

## Results

The experiment showed that the probability of the marbles falling into each compartment followed a bell curve. The results were consistent within 5% each trial.

## Why do this project?

This science project is interesting because it shows how a bell curve can be used to predict probability.

## Also Consider

Experiment variations to consider include using different sizes of marbles or different sizes of compartments.
