In a simple circuit, does electricity start instantly? A simulation encourages thinking about the flow of electrons at a microscopic level. Pupils control the voltage, resistance, and switch in order to observe the change in both ideal...

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

How does electricity travel through power lines? The simulation demonstrates the how changes in voltage and resistance are related to the distance between power polls and the thickness of the cable. Scholars control three variables in...

Learners explore the concept of electricity in this activity based unit.  In this physical science lesson, students focus on electricity and electrical engineering. The teaching unit includes 5 activities to develop learners...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

Students conduct an experiment to find out how well different wires radiate heat when voltage is applied across the wire. They use the results of their experiments to consider how the gauge of the wire and the type of wire affect the...

Train a budding electrician about the principles of electricity and the wiring materials needed to complete the job. Briefly covered are basic electrical concepts such as, volts, watts, circuits, and safety. Also covered are the...

Investigate the maximum power output of a photovoltaic panel with a lesson that introduces the class to the maximum power point. Individuals learn how to determine the maximum power point of a solar panel by using Ohm's law and the power...

Fifth graders explore electrical concepts and host a guest speaker. This lesson sets up guidelines for students to follow when they have a guest speaker. Students are primed to become actively involved in a lecture or discussion, while...

Students light a LED clock or light bulb using potatoes. They examine how a battery works in a simple circuit. They determine how chemical energy changes to electrical energy while experimenting with potato powered circuits.
