People often draw conclusions from a small number of observations, and use those conclusions to evaluate the likelihood that an event will take place. But how easy is it to draw the wrong conclusion based on those observations? Will your predictions be accurate if an experiment is only performed a few times? The objective of this project is to determine what happens when a test with two equally-likely outcomes is performed only a small number of times. You can test this by flipping a coin. A… Read more

Math can make you money! If you understand some basic math, you can make good decisions about how to keep, spend, and use your hard earned dollars. Try an experiment comparing the same balance in different types of bank accounts. How much better is a savings account than a checking account? What difference does the interest rate make? Which is better, an account that earns compound or simple interest? Can you compare the short and long term costs of borrowing money compared to saving the cash… Read more

Yogurt is a very versatile dairy product. It's yummy eaten straight from the container, it is good for your digestive system, and it can be used in several ways for cooking. There is historical evidence that yogurt-making developed 4,500 years ago! Humans depended on yogurt-making as a way to preserve milk. Yogurt is the result of bacterial fermentation of milk. In fermentation, the bacteria consume the milk sugar, lactose, and produce lactic acid. The end-product is a thick, creamy, and tangy… Read more

Have you ever noticed that hip-hop songs have a fast tempo, while country ballads are usually slow? Do you think there is a correlation between the number of beats per minute (bpm) in a song and the type of music? You can explore whether different genres of music have different bpm ranges by measuring the bpm in several different songs from a number of different genres. Bpm can be measured using free music software, like the one listed below in the Bibliography, or by counting all the beats you… Read more

How do you turn a 2-dimensional piece of paper into a 3-dimensional work of art? Origami, the classical art of Japanese paper folding, is loaded with mathematical themes and concepts. What are the common folds in origami, and how do they combine to create 3-dimensional structure? Can you classify different types of origami into classes based upon the types of folds they use? Can you show Kawasaki's Theorem, that if you add up the angle measurements of every other angle around a point, the sum… Read more

Whipped egg whites are used in many sweet and savory recipes. They are used to add air into cake batters, meringues, and soufflés. Egg whites, also known as albumin are 15 percent protein dissolved into water. When egg whites are beaten or whipped, the protein chains unravel. This is called denaturation. The process of whipping egg whites adds air to the mixture, in addition to denaturing the proteins. The denatured proteins create bonds with each other and trap air bubbles within… Read more

A concert piano. It's a beautiful instrument and a spectacular sight when it's all set up on stage. The first thing you may notice when you first look at a concert piano is the impressive-looking soundboard, that large board on the back of the piano that is tilted up at an angle. It is used for amplification. The sound board greatly increases the volume of sound coming from vibrations of the strings. The soundboard is positioned so that it gathers the sound vibrations coming from the strings… Read more
