Science Buddies: Solar Cell Power Output vs. Temperature
Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature.

Science Buddies: Rubbing Up Against Static Electricity
A tried and true balloon activity is to rub a balloon on your head to make your hair stand up. Learn how the rubbing builds up static electricity using this experiment to see if the number of rubs makes a difference.

Science Buddies: How Do Different Materials React to Static Electricity?
Polyester clothing was generally accepted as a popular trend in fashion at one point in history. Now everybody wears cotton, which doesn't get static cling nearly as much. Why are some materials more susceptible to static cling than...

Science Buddies: Rock On! Recording Digital Data With Magnets
This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data...

Science Buddies: How Far Can Sparks Jump?
Piezoelectric barbecue fire starters work by creating a spark that ignites the volatile lighter fluid, which then starts the charcoal burning. They are low current, high voltage devices. This project shows you a way to find out by with...

Science Buddies: Which Materials Are the Best Conductors?
There are two main types of materials when it comes to electricity, conductors, and insulators. What are they made of? Find out by testing different materials in a circuit to see which ones conduct the most electricity.

Science Buddies: Testing a Parabolic Reflector With Light From an Led
You can see examples of parabolic reflectors in flashlights, car headlights, satellite TV antennas, and even on the sidelines at football games. In this project, you can use an LED and a simple photodector to investigate this concept.

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...
