Science Fair Project Idea
Wouldn't it be nice to avoid those nasty electric shocks you get after you have walked around on carpet and then shake a friend's hand, or all those crazy flyaways you get after brushing your hair? These are caused by static electricity. In this science fair project, you will build a super-sensitive charge detector to investigate the positive and negative electric fields created by static electricity. The detector can sense invisible electric fields, so try this science fair project to avoid… Read more

When you were little, did you ever make "music" in your kitchen by banging kitchen utensils on pots and pans? What if you could actually take those kitchen implements now, and play them with different sound effects? In this project, you can convert basic kitchen utensils into your own electronic drum set using the Science Buddies . Check out the video to see what this simple, but fun, project looks like: This project requires use of a tiny computer called a Raspberry Pi… Read more

Science Fair Project Idea
"Waste not, want not" is a common saying. These four words sum up an important principle: if you "waste" an important resource, you might find you don't have enough of it when you "want" it. One of the most important resources we have is clean water. In many parts of the world, including the western part of the United States, water shortages pose serious problems. In this science project, you will build an electronic circuit that can 1) detect when it is raining and 2) shut off power, such as… Read more

Science Fair Project Idea
If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels. Read more
