Wikipedia defines mathematics as "the study of quantity, structure, space and change." With a definition like that, it's easy to see why math is often called "the language of science." Math is essential for analyzing and communicating scientific results, and for stating scientific theories in a way that is clear, succinct, and testable.

85 reviews
Do you ever use math as a tool to solve interesting problems? In the 1970s math was often taught with simple worksheets. One teacher developed an exciting way to learn math and logic; he developed what is now known as the perimeter magic triangle puzzles. Try them out—and have some fun as you start thinking about counting in a whole new way! Read more
Basketball: The Geometry of Banking a Basket
Science Fair Project Idea
Scientific Method
If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more
M&M Math
Science Fair Project Idea
Scientific Method
It has been said that, "Life is like a box of chocolates—you never know what you're going to get" (Forrest Gump in Forrest Gump, 1994). In this science project you can test the "Forrest Gump Chaos Theory" by using M&M's®, which are much cheaper than a box of chocolates. What if life is more like a bag of M&M's? Find out in this science project if some things in life are predictable by using the awesome power of statistics. Read more
Chain Reaction: Inversion and the Pappus Chain Theorem
Science Fair Project Idea
Scientific Method
Here is a challenging problem for anyone with an interest in geometry. This project requires background research to solve it, but it is an excellent illustration of visual thinking in mathematics. Figure 1 below shows a series of circles (iC₁, iC₂, iC₃, ..., iC₃₀), inscribed inside an arbelos. What is an arbelos? The arbelos is the white region in the figure, bounded by three semicircles. The diameters of the three semicircles are all on the same line segment, AC,… Read more
Design Your Own 3D Printed Optical Illusion
Science Fair Project Idea
Engineering Design Process
The "impossible arrow" is an amazing optical illusion: an arrow that always seems to point to the right, even when you rotate it 180°. If you place the arrow in front of a mirror, however, its reflection points to the left! How does this illusion work? Can you design your own "impossible" shapes? Try this project and find out!

Hacking the Air Gap: Stealing Data from a Computer that isn't Connected to the Internet
Science Fair Project Idea
Scientific Method
You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use a smartphone equipped with a sensor app to demonstrate how the data can be picked up by a nearby… Read more

Have you ever heard anyone say the chance of something happening is "50-50"? What does that actually mean? This phrase has something to do with probability. Probability tells you how likely it is that an event will occur. This means that for certain events you can actually calculate how likely it is that they will happen. In this activity, you will do these calculations and then test if your calculations hold true for reality! Read more

Did you ever come across a challenge that looked almost too straightforward to try, but turned out to be shockingly tricky, if not impossible?  This activity challenges you in a fun way. Something as simple as picking up a piece of candy can be way harder than it looks. Find out why some movements are harder than you’d expect, then trick your friends into trying them. Astonish them with your stunning knowledge of the laws of physics; and most of all, have fun! Read more
Bet You Can't Hit Me! The Science of Catapult Statistics
Science Fair Project Idea
Scientific Method
If you have ever tried to hit a target (such as a trash can) with a wad of paper, you know that aim is everything. But it is not always easy to get it right every time! Missing is not that big a deal with a wad of paper, but what if you were in an invading army in the Middle Ages, using a catapult to hurl huge stones and knock down castle walls? For a successful invasion, it would be important to know exactly how far, and how reliably, a catapult could launch a projectile. In this project you… Read more

Mathematicians look at the world around them in terms of numbers and formulas, and now, you can discover the formula for Pi too! In this science activity you will examine circular objects and see what you can discover about their sizes. As you explore, you might be surprised at how useful the results can be—maybe it will inspire you to save up for a bike with bigger wheels! Read more
