Science Buddies: How Many Letters?
Can you remember all of your ABC's? Computers need to "remember" letters too. Every time we use a computer to write a story, the computer needs to "remember" the letters in the story by saving them to the computer's memory as a file. In...

Science Buddies: How Does Soil Affect the P H of Water?
Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens...

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: Understand Shock Levels and Packaging Principles
When you open up your presents on your birthday, you probably don't spend a lot of time admiring the wrapping-you'd much rather see what's inside. It can be the same way with the packaging that products come in, but packaging is...

Science Buddies: Digital Pinhole Camera
If you sit under a leafy tree on a sunny day, you may notice spots of sunlight on the ground from light passing through spaces between the leaves. Try putting a piece of cardboard on the ground and examining the spots of light on the...

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: Porosity and Particle Size
Often, when we think of something that is solid we think about rocks. But in reality, rocks have tiny holes of air inside them. This is called porosity. In this experiment you can find out what it means to be "solid as a rock."
