Curated OER
OHM's Law
Students study the relationship between current, voltage and resistance in a series circuit. In this investigative lesson students watch a demonstration and see how voltage is measured and see what OHM's law is.
Curated OER
Construction of an Ammeter and a Voltmeter from a Galvanometer
Students explore series and parallel circuits. In this physics lesson, students construct a simple circuit and measure its maximum current. They construct their own voltmeter and ammeter that operates at a specified range.
Curated OER
Map Field of Current
Students determine that moving charges create a magnetic field. They discover that the speed and direction of motion, the amount of charge, and the deflection angle observed are closely linked. A voltmeter, pendulum, and a constructed...
Curated OER
Apartheid and Segregation
Students view a television program that depicts the history South African Apartheid and the United States' system of segregation. They discuss how laws were used to uphold these institutions and compare and contrast racism and...
Curated OER
Electric Current and Resistance
Students are introduced to the topics of electric currents and resistance. In groups, they distinguish the difference between conventional and electron flows and state Ohm's Law for electrical components. They calculate the resistance of...
Curated OER
Maximum Power Point
Students investigate how to optimize the power output of a photovoltaic cell using a home-made gnomon stand. They use data collected to create current-voltage and power-voltage curves to determine the "maximum PowerPoint," (MPP) at which...
Curated OER
Magnets
In this magnets worksheet, high schoolers describe the differences between a generator and a motor, define electromagnet, and identify a circuit as parallel or series. This worksheet has 2 short answer questions, 5 fill in the blank and...
Curated OER
2010 Electricity
In this electricity worksheet, high schoolers determine if the circuits shown are parallel or series, calculate the voltage, and the power used by the light bulbs. This worksheet has 11 problems to solve.
