Water Model of Electricity

Created by Nathan Wilson for the University of Washington Clean Energy Institute Overview: The goal of this activity is to allow students to apply their knowledge of Ohm’s law to a more intuitive and visual system: water flowing through tubes. The total time for this activity is around 30 minutes. Students are assumed to be familiar Ohm’s law (V/R=I) where V is volts, R is resistance, and I is current, as well as the formula for calculating the resistance of a resistor (R=ρl/A).  where p is resistivity in ohms/meter, l is length, A is area of the conductor. Essential Question: How can we model the behavior of electricity...
