Measuring the value of a resistor with an ohmmeter is pretty simple. You connect the meter to the resistor, and read off the measurement from the meter. But what if the resistance you want to measure is very low? This project shows you how to use a four-point resistance measurement method to measure low resistance values. Read more

Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Read more

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

LEDs (light-emitting diodes) are electronic components that convert a portion of the electrical energy flowing through them into light. How does the intensity of the light produced vary with the current flowing through the LED? To find out, you'll build some simple circuits to vary the current flowing an LED. You'll also build a simple light-to-voltage converter circuit to measure LED output. Read more
