Science Buddies: Gears Go Round!
Music boxes, bicycles, and clocks all have one thing in common: GEARS. You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in...

Science Buddies: How Does Color Affect Heating by Absorption of Light?
Light is an example of an electromagnetic wave. Electromagnetic waves can travel through the vacuum of interstellar space. They do not depend on an external medium-unlike a mechanical wave such as a sound wave which must travel through...

Science Buddies: Using a Digital Camera to Measure Skyglow
This is a great project for someone that is interested in both stargazing and photography. Bright city lights and even the light of the full moon obscure the dimmest stars, which can make identifying constellations more difficult. This...

Science Buddies: Measuring Light Intensity Using the Inverse Square Law
You've probably heard that compact fluorescent light bulbs are more efficient than incandescent bulbs. More of the electricity they use goes into producing light, and less into producing heat than with incandescent bulbs. How much more...

Science Buddies: What Makes a Dna Fingerprint Unique?
Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events.

Science Buddies: A Magnetic Primer Designer
How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a primer that will stick to the piece of DNA you want to copy, called a template. In this...

Science Buddies: How Atmospheric Temperature Affects the Water Content of Snow?
If you're lucky enough to live in a place that gets snow in winter, you know that the feel of the snow can vary a lot. Sometimes it can be light and fluffy, and other times heavy and wet. This project shows you how to use data from daily...

Science Buddies: Investigate Mpemba Effect Can Hot Water Freeze Faster Than Cold
This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out...

Science Buddies: Supercooling Water and Snap Freezing
Can water remain liquid below its normal freezing point? If it does, that water is supercool(-ed). This project shows you a method for supercooling water. You can test water from different sources to see whether or not it can be...

Science Buddies: Using Weather Balloon Data to Map Atmospheric Temperature
Snow-capped mountains make a picturesque scene, especially in summertime when the peaks are in such contrast to the warmth below. This project shows you a way to see how temperature changes with altitude using data collected twice daily...

Science Buddies: Ring of Fire 2: What Earthquakes Tell Us About Plate Tectonics
The theory of plate tectonics revolutionized geology in the 1960's. In this project you can explore the connection between plate tectonics and earthquakes by mapping historical seismic data.

Science Buddies: What's the Point of Boiling?
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...
