Did you know that the average child sees 20,000 30-second TV commercials in just one year? That's a lot of encouragement to buy new toys, clothes, entertainment, and food. In this behavioral science fair project, you'll find out some other ways (besides commercials) that marketers use to try and get adults to buy products, like having them touch or hold an item. You'll find out if these methods work with kids, too, and if they increase how much people are willing to pay for a product. It's a…

In the fairy tale of the three little pigs, the wolf huffed and puffed and blew down the first pig's straw house. But in reality, straw, tied into bales, is a viable building material that, when used properly, makes sturdy and energy-efficient buildings. Straw is a renewable resource that is available all over the world since it is the byproduct of growing grain. In this science fair project, you will test a straw bale covered with stucco to see if it's water resistant, and evaluate if it's…

In this week's spotlight: a human biology and health project that puts an important question to the test: if you exercise regularly, does your heart recover from exertion more quickly than if you don't exercise often? The heart pumps faster during exercise, which helps to keep the heart healthy. It is good to exercise frequently and to raise your heart rate into its target heart rate zone during exercise, but how long does it take for the heart to return to its normal…

Helmholtz resonance, or air cavity resonance, refers to the resonance of air in a container with a small opening, like a plastic bottle or the devices shown in Figure 1. The resonant frequency of the air depends on the volume of the air in the container and the geometry of the opening (its length and cross-sectional area). The Helmholtz frequency is not the same as the natural frequency of an air column in a cylinder, where the opening is the same size and shape as the rest of the cylinder. …
