Concord Consortium: Calculating Voltage in Series Parallel Circuits
Use the series and parallel resistance formulas to determine the total resistances of the parts. Then, use Ohm's Law to calculate the voltage drops across each part.
Concord Consortium
Concord Consortium: Total Resistance in Series Parallel Circuits
Use the formula for the parallel resistors to calculate the total resistance in series-parallel circuits.
Concord Consortium
Concord Consortium: Calculating Current in Parallel Circuits
Use Ohm's Law to calculate the current in parallel circuits.
Concord Consortium
Concord Consortium: Measuring Current in Parallel Circuits
When measuring the current in parallel circuits, compare the circuit's total current with the current through just one resistor.
Concord Consortium
Concord Consortium: Total Resistance for Resistors in Parallel
See how this application of Ohm's Law leads to a formula for the total of parallel resistances.

Concord Consortium: Dam Removing: Changes in the Environment Affect Population
What happens to a population when the environment changes? Students remove a dam that divides an ecosystem to illustrate the effects of environmental changes. Students observe and collect data as the grass and then the rabbit populations...
Concord Consortium
Concord Consortium: Dam Building: How Changes in Environment Affect Population
In this simulation, students build a dam in the middle of a field, dividing an ecosystem in half to illustrate the effects of environmental changes. They watch and collect data as the grass and then the rabbit populations in that region...
