 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

 If you have a multi-speed bike, you know that you can make it easier or harder to pedal just by shifting gears. Ever wonder how that works? You can investigate this a number of ways. A basic approach is to use a selection of spools of thread (with different diameters), a board with two nails, and a rubber band. Place a spool over each nail, and put the rubber band over them. Mark the 12:00 position on each spool so that you can count revolutions. Turn one spool through a full circle and… 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

 Get good photographs of the Moon showing lots of craters and count how many craters you find in a range of diameter classes. One useful source is the (Kuiper et al, 2006). Make a histogram that shows the distribution of diameters. Most of these craters were formed during the first billion years of the Moon's formation, but you should confirm that this is true for the the Moon areas you've selected in your photographs by doing background research. Is cratering uniform across the surface of the… Read more

 Learn how to edit sound files so that you can manipulate the recorded sound mathematically. You can either find specialized audio editing software or do background research to teach yourself about sound file structure so that you can write your own simple program to manipulate sound files. Try arithmetic operations on the sound values (e.g., adding or subtracting a constant, multiplying or dividing by a constant). How do these operations alter the sound? Try other mathematical operations:… 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

 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

 One thing that all living things have in common is that they grow through cell division. How is this growth regulated? Sometimes growth occurs when it is not supposed to, leading to cancer. Scientists are trying to discover how growth is regulated, hoping to find potential cures for cancer. One idea is that cells keep track of growth using special regions of the chromosome called "telomeres" that count how many divisions a cell has made. If this is true, then growth, cell division and age are… Read more

 The different species of wood used in construction offer a variety of challenges based on density, porosity, oils in the wood, flexibility, elasticity, etc. The intended use, e.g., structural or cosmetic, presents different challenges as well. The glue must be compatible with the wood, the use, and the climate, so many experiments are possible. For example, you could design an experiment to test the durability of different adhesives using the same wood. Or, you could try different wood… Read more
