Curated OER
From Sunlight to Electric Current
Students explore concept of current in electrical circuits. They examine how energy from the sun can be used to power everyday items, including vehicles.
Curated OER
Electricity – Ohm’s Law
Students investigate the relationship between voltage and current. In this physics lesson, students observe and collect data from the experiment. They graph the result and share them to class.
Curated OER
TE Activity: Ohm's Law 2
Students study Ohm's Law 2 after completing an activity about Ohm's Law 1. They determine how long it takes to charge a battery. They examine if it is better to use batteries in series or parallel circuits.
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
Electrons on the Move
Fourth graders study current electricity while constructing a simple electric circuit. They build a galvanic cell to examine the concepts of voltage, current and resistance.
Curated OER
Ohm's Law
Students explain the meaning of Ohm's Law, and plot a graph of voltage versus current, by explaining how the slope is the resistance of the circuit.
Curated OER
Ohm's Law, Watt's Law and Solving Formulas.
Young scholars, in groups, connect a 10 ohm resistor across their 1.5 volt battery, and take voltage readings every 5 minutes.
