Students generate experimental questions regarding conductors of electricity, plug cord into pickle, and measure and graph voltage drop across electrodes. Students then compare to variety of other conductors of their choosing.

Students explore electrical resistance through various experiments. In this physics instructional activity, students calculate resistance using a mathematical formula. They explain how colors identify the resistance value of a resistor.

High schoolers explore using a circuit board in this physics lesson. They will analyze current and battery set up on a circuit board. Teachers check the board before the students experiment.

Students investigate electric circuits. In this electricity lesson, students observe illumination in a series and parallel circuits. They predict and calculate the resistance in each type of circuit using a voltmeter.

Students list as many examples as they can of sensors in their homes and/or automobiles, define sensor and discuss what qualifies devices as sensors, explore human eyes as sensors while watching teacher demonstration, recognize that...

Students explore simple electrical circuits. Students experiment, using different configurations, to determine what is necessary to compeete a circuit. Students observe similarities between arrangements that work and differences in...
