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…

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…

What variables contribute to the properties of the soil in an area? Investigate the role of climate, weather, topography, time, parent material, vegetation, and biological and chemical agents on soil formation. How are soils characterized? There are 3 basic particle sizes which create three basic soil types: sand, silt, and clay. Investigate the properties of the three different types of soil by observing grain size, shape, hardness, color, chemical composition, pore space, aeration,…

This project can apply to soccer, hockey, baseball and many other sports. What is the effect of stopping the kick/shot/swing at the moment of impact vs. following through? Think of a way to measure the outcome in each case, and explain your results. (idea from Gardner, 2000, 83-85; for more information with regard to specific sports, see: Barr, 1990, 12-14; Gay, 2004, 142-144; Adair, 2002, 30.)
