Golden Rules of Photography: Family Science Spotlight
Blog Post
Try this hands-on science experiment to learn about the golden rules of photography and improve your photo compositions. When you take a photo, do you put the subject right in the center? What happens to the same photo if you move the subject to the right of the frame, or to the left? These are questions a photographer asks herself every time she gets ready to snap a photo. Where should the subject "go" in the frame? In making this decision, a… Read more
Golf Clubs, Loft Angle, and Distance: The Science of Hitting
Science Fair Project Idea
Scientific Method
Use a video camera to analyze the angle of lift with different clubs. Measure the distance the ball travels. Be sure to conduct a sufficient number of trials with each club so that your results are consistent. This can also be a great way to work on your swing! (Idea from Goodstein, 1999, 83-85.) Read more

Growing a Soil Menagerie
Science Fair Project Idea
Scientific Method
Everything on our planet is connected together, linked by a giant recycling system called the biogeochemical cycle. It is an amazing process. You can actually investigate how our planet recycles and reuses everything needed to support life by making a small model of the biosphere. What will be important to include in your miniature system so that it can support different types of life? Read more
Guitar Jingle: Discovering the Locations of Harmonics

Hands-on Shopping: More Likely to Buy if You Can Give It a Try?
Science Fair Project Idea
Scientific Method
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… Read more
He Huffed, and He Puffed, But Didn't Blow the House Down! How Can Straw Make a Sturdy Building?
Science Fair Project Idea
Scientific Method
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… Read more
Heart Health: Weekly Science Project Idea and Home Science Activity Spotlight
Blog Post
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… Read more
