Have you ever wondered why rubbing a balloon or a blanket—or even a winter hat—on your head makes your hair stand up? The effect is due to static electricity, but how is the static electricity made, and why does it make your hair stand on end? Static electricity is the buildup of electrical charge in an object. Sometimes static electricity can suddenly discharge, such as when a bolt of lightning flashes through the sky. Other times, static electricity can cause objects to cling… Read more

Runoff and Fertilizer Use

Science Fair Project Idea

Scientific Method

Many people routinely use fertilizer for crops, gardens, and lawns. What people don't know is that each time they apply fertilizer, the fertilizer seeps through the soil into the water table. This can eventually lead to the contamination of a local water source, like a stream, pond, lake, bay, or ocean. This is an especially big problem for agricultural practices that frequently use large amounts of fertilizer on fields that are connected by irrigation channels. The run-off of fertilizer… Read more

Have you ever lived someplace where you get to experience the full glory of all four seasons? If so, you know well the heady blossoms and dramatic skies of spring; the long, sun-drenched days of summer; the trees shaking in crimson and gold in fall; and the sparkling, brittle snows of winter. But do you know why we have these seasons, over and over again, in a cycle as predictable as the rising and setting of the sun? It actually has to do with the Earth’s tilt and the Moon. In this… Read more

Seasons Science: Weekly Science Project Idea and Home Science Activity Spotlight

Seeing Beyond the Visible: Photography with Near Infrared Illumination

Science Fair Project Idea

Scientific Method

Have you ever wondered what it would be like to have an extra sense? What if you could hear above the normal range (ultrasound) like dogs or bats? What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world. Read more
