Homopolar motor
This simple project was done as a demonstration for Science Club. We were discussing how a speaker works. In fact, all movement due to electricity is caused by the same effect: the interaction of a moving charge in a magnetic field. In this case, the electric current is moving from the positive end of the…

Strobe effects
Learning objectives: Understand how a strobe light works and how it can be used Understand why a strobe light makes it look like motion stops Use an oscilloscope to visualize a changing current Understand how the timer circuit we made previously can be used to detect lighting conditions Understand how the timer circuit can be…

Sound
Learning objectives: Understand the difference between longitudinal and transverse waves Know that frequency is measured in units called Hertz, which is abbreviated Hz, which represents the number of cycles/second. Know that humans can hear frequencies from about 20 Hz to 20,000 Hz. Understand that the amplitude of a sound wave determines how loud it is.…

Cartesian Coordinates
What is the Cartesian Coordinate System? The Cartesian coordinate system is a way to locate a point in space by assigning coordinates at 90 degrees to each other. The Fundamental Skills: The fundamental skills involved include: Understanding how to find a point given its coordinates Understanding how to assign coordinates to a point Understanding how…
