### E.T. Do Math

No one knows for sure if intelligent extraterrestrial life exists or ever existed. But many believe intelligent beings live elsewhere, despite a complete lack of compelling physical evidence. Why do s ...

### Testing the Birthday Paradox

The birthday paradox states that in a room of just 23 people, there is a 50/50 chance that two people will have same birthday. In a room of 75, there is a 99.9% chance of finding two people with the s ...

### Mathematical Modeling of Bacterial Growth

This experiment will introduce students to the mathematical modeling of biological processes. Students will fit the growth pattern of bacteria to a mathematical model and predict future colony expansi ...

### Iterating Fractals

Fractals are on the cutting edge of mathematics because deep exploration of their properties was not possible without modern technology. Basically, a fractal is a geometric shape that is self-similar, ...

### A Fractal in a Fractal

This experiment will explore whether fractals really repeat themselves infinitely. Are fractals really self-similar? How far must one zoom into a fractal to find an exact replica of the whole fractal? ...

### Oregametry

Origami is an ancient Japanese art form that’s wildly popular among the arts & crafts crowd.But most of us don’t realize that techniques used in standard origami folding have aided the design and deve ...

### Order in Chaos

Iterated algorithms are very important for mathematics today. By repeating equations, scientists are finding brand new things out about the natural world (populations, epidemics, etc.). Iterated algor ...

### Is Parallax an Accurate Measure of Distance?

Motion parallax” is easily demonstrable by closing one eye, staring at a pencil, and then opening the closed eye and closing the other. The pencil appears to move because the eyes have different locat ...

### The Statistics of Sunspots

Sunspots are disturbed areas of the sun that look like spots because they are cooler than the surface of the sun. They have been observed and recorded since the 18th Century. This large collection of ...

### Apparent Movement of the Sun

Every day, the Sun rises in the east, rides across the sky, and sets in the west. Once upon a time, people thought gods like Apollo carried the Sun on a chariot. But as it turns out, the Sun doesn’t m ...
