When the punter is trying to hit the "coffin corner" (within the opposing team's 10-yard line), out of bounds, what is the best angle to kick the ball for correct distance and maximum "hang time?" (For more information on the physics involved, see: Gay, 2004, Chapters 4 and 5.) Read more

Soil liquefaction is a phenomenon where soil that is saturated with water suddenly loses its strength and behaves like a liquid. This usually occurs due to sudden, large stresses on the soil — for example, from an earthquake. This can be very dangerous for buildings sitting on top of the soil, as they can suddenly sink into the ground! The embedded video explains soil liquefaction in more detail. Is there a way to prevent soil liquefaction? Do you think adding… Read more

Can you imagine Valentine's Day or Halloween without chocolate? Well, if you're a chocolate lover brace yourself for the bad news. According to the United States Department of Agriculture (USDA), "Worldwide demand for cacao now exceeds production." If there isn't enough cacao, the major raw ingredient for chocolate, then the chocolate supply will dwindle. Hang on! Before you start rushing to the store to buy all the chocolate you can get your hands on, a solution is already in the works. In… Read more

We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,… Read more

If you like to fish and you'd rather not be telling the story of "the one that got away," then this is a project for you. What combination of properties makes for the best fishing line? Here are some suggestions for getting started on your background research into fishing line properties: knot strength, abrasion strength, shock strength, tensile strength, limpness, controlled stretch, and desired range of visibility (Dodson, 2006). Choose the properties that you think are most important, and… Read more

How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the to access, view, and download information from geospatial databases containing a broad spectrum of data produced by the… Read more

It is important to ensure that we all have good clean water to drink that is not contaminated by heavy metals or chemicals. One common pollutant in a water supply is lead in old pipes or paints that can leach into the water and cause lead poisoning. There are different kits available for testing the presence of lead and other contaminants in water. Test your water supply, and also the water in some local ponds, lakes or streams. The same contaminants that can harm you can also harm wildlife. … Read more

Some plants use a lot of water, and some are very drought-tolerant. Drought-tolerant grasses are good for water conservation because they require less water to grow and stay green. How much less water do they need? Which types of grass are drought-tolerant? You can buy different types or brands of grass seed at your nursery that claim to be drought-tolerant. Grow them in a container and then starve for water after they are established. Which brands die out first? You can conduct a similar… Read more

You can make a very simple hovercraft with a stiff, disposable plate-a pie plate should work well-and a balloon. Glue a square of cardboard in the center of the bottom of the plate. Make a small hole through the center of both of these layers. Enlarge the hole slightly with a pencil. Push a balloon through the hole so that the opening is on the front side of the plate, and rest of the balloon sticks out from the back. Blow up the balloon, then set the plate down (balloon side up). What… Read more

Here's a project idea for all of you bakers out there. What happens if you try your favorite muffin recipe with different types of flour (e.g., white, whole wheat, rye, soy, etc.)? Think of ways you can measure the results. How would you measure the density of a muffin? A kitchen scale would definitely be useful for this project, both for measuring the results and for portioning out the batter for equal-sized muffins. What other measures might be of interest?
