thumbnail 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

Try gluing wood together with different types of glue, e.g.: regular white glue, yellow wood glue, cyanoacrylate (super glue), and Liquid Nails. Glue a short piece (5-8 cm) to the center of a longer piece (15-30 cm). After the glue has dried for the recommended time, drill a small hole through the center of the joint, big enough to pass through a piece of coat-hanger wire. Cut a length of coat hanger wire, pass it through the hole, and twist the ends together to form a loop. Place the ends… Read more

How strongly do different types of nails hold in wood? Try different diameters of nails, and try pounding them to different depths. To gauge the holding strength, measure how difficult it is to remove the nail. Can you pull it out with a pair of pliers? Can you remove it with the hammer claw? Do you have to push only a little bit, moderately hard, or as hard as you can? Do you need a crowbar? What happens if you pre-drill holes for the nails, using drill bits that are different… Read more

thumbnail French fries, hash browns, mashed potatoes with gravy, potato latkes, there are so many things to make with the humble potato. The potato is a tuber from the perennial plant Solanum Tuberosum of the Solanaceae family. There are actually about 5,000 varieties of potatoes, but most of them can be traced back to the original potato from southern Peru. This single ancestor originated more than 10,000 years ago. In addition to being high in vitamins and minerals, potatoes have a varying amount of… 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

Math is used by many different types of scientists to model phenomenon and evaluate data from an experiment. By building mathematical models scientists can understand how different physical, chemical, and biological processes are affected by different variables. The most important tools are: making a graph to give a visual representation of the relationships between your variables and making an equation to give a way of computing the relationships between your variables. Find a source of data,… Read more

Do violin students have better relative pitch than piano students? Since the violin requires the player to choose the correct location to stop the string in order to sound the proper note, you might think that violin players would, as a result of practice, have better ear training than piano students. On the other hand, you could argue the opposite viewpoint, since piano students would have the benefit of hearing correct intervals (assuming that the piano is in tune). Which hypothesis do you… Read more

thumbnail Have you ever had to take prescription medicine to get over an illness? To get better, it is important to take the medication in the proper manner and at the proper time. Wouldn't it be cool if there were a tool or piece of automated equipment that held your medicine and reminded you to take it? A tool that would know when you picked up the bottle and took your medicine? Building a smart medicine cabinet is what this science project is all about! Read more

During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… Read more

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of… Read more
