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
Batteries in Series: Voltage and Light Intensity
Students participate in a hands-on activity to explore the relationship between the number of batteries in a series circuit and its voltage. Students identify the relationship between two variables and plot points on a graph.
Curated OER
Lights On!
Students work together to build their own simple circuits. They discover how electricity is conducted through light bulbs. They compare and contrast the differences beween a parallel and series circuit.
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
Using Transistors: Let's Get Transistorized!
Students build two circuits and explore how transistors function. This activity allow them to observe the operation of a transistor as an amplifier.
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
Three Switches
Students describe the types and parts of a circuit. They discover three types of electrical switches and create a chart showing the many uses for each type of switch.
Curated OER
Circuits and Conductors
Students participate in an online lesson to explain the conductivity of different materials and the effect of changing the power source.
Curated OER
Changing Circuits
Students participate in an online lesson to explain how to make bulbs brighter or dimmer in a series circuit by changing the number or type of components.
