Science Buddies: Tightening the Turns in Speed Skating
Fast turns around the track can become your laboratory tests in these experiments, whether you skate on ice, wood, or pavement. The goal is to determine which type of turns are best in a race - tight, medium, or wide - and then to figure...

Science Buddies: How Does the Intensity of Light Change With Distance?
How far would you have to travel so that the light of the full sun would provide "daylight" no brighter than twilight on Earth? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and...

Science Buddies: How Do Roots Grow When the Direction of Gravity Changes?
You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

Science Buddies: What Goes Up, Must Come Down
Standing on a balcony near the top of the 179-foot tall Tower of Pisa, a young scientist dropped two iron balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying...
