Students describe how resistors affect the flow of electricity. In this electronics lesson plan students examine transistors and what they do and how they work.

Learners discover how galvanic exchange has contributed tot he deterioration of the Titanic. They perform an experiment in which they predict which of 2 metals deteriorate when placed in a salt solution.

Young scholars conduct experiments on a sample of sea water. In this oceanography lesson, students inquire how conductivity is used to approximate the salinity ocean water. Young scholars construct their own conductivity meters and...

Young scholars review new terminology and computer circuits and the value of a resistor. They complete three experiments, "Resistance Activities," Transistor Activities,"Diode Activities" and enter data, results and their findings on...

Learners explain the concepts of charge storage and how a capacitor works. They construct a capacitor and measure the stored charge using the appropriate equipment and measurements. They also demonstrate capacitance and how it can be...

Students track and record data on the Sun's position in the sky and on the output of a solar panel tracking the Sun. On a second day, students graph and analyze the data to identify relationships between (1) the time of day, (2) the...

Students identify and implement methods to standardize testing stations that measure solar panel output power. After collecting electrical ouptut data from several solar panels, they plot the current-voltage and power curves. Students...

A discussion of various principles related to voltage. The operation of battery testers and voltmeters are explained. The importance of the internal resistance of a power source is discussed.

Frankenstein's electricity is out. In this activity, students help him find another source of energy using citrus fruit. Good for students who want to do their own projects or for class lessons.
