In this interactive, students can explore how current, voltage, and resistance are related in a model showing the flow of electrons in an electric circuit. They will learn about Ohm's law and how other forms of energy can be made from...

This tutorial introduces the concept of electric currents. Take the interactive quiz to assess your understanding.

This tutorial illustrates how the flow of water through a system of pipes can be used to understand the flow of current through an electric circuit.

[Free Registration/Login may be required to access all resource tools.] Using diagrams, video clips, and informational text, students learn how electrical current flows through a series circuit.

Kids learn about electric current in the science of physics including the flow of electrons, measurement, alternating, and direct current.

This lesson focuses on electric charges. Electric current is the flow of electric charge. Some insulating materials become electrically charged when they are rubbed together. A substance that gains electrons becomes negatively charged,...

For this fifth grade activity, young scholars explore electric circuits by acting out different types, then construct circuits themselves.

A simple science fair project to test whether electricity can flow between two things. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms,...

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. This will lead to the principle of "Conservation of...

Students build a saltwater circuit, which is an electrical circuit that uses saltwater as part of the circuit. Students investigate the conductivity of saltwater, and develop an understanding of how the amount of salt in a solution...

A teacher lesson plan which could be easily converted into an idea for a student project or presentation. This page describes an activity in which the water-electricity analogy is used to investigate the relationship between current,...

This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the...

Brush up on electricity facts before taking this interactive quiz. Students can get immediate feedback by checking the answers after each question.

Teacher directed activity shows students how flowing electrical current produces a magnetic field by building a simple motor.

Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting...

Students are presented with a short lesson on the Coulter principle, an electronic method to detect microscopic particles and determine their concentration in fluid. Depending on the focus of study, students can investigate the...

Lesson focuses on how switches control the flow of electricity. Students are posed with the challenge of designing and building a simple switch into an electric circuit.

This lesson focuses on Mains Electricity and Alternating Current. Electrical supplies can be direct current (DC) or alternating current (AC). The UK mains electricity supply is about 230V at 50 Hz. It explains the difference between AC...

Find out how measuring current in a circuit is like measuring the flow rate of water in a sprinkler system.

[Free Registration/Login Required] This flipchart provides an introduction to electrical power to be used for AP Physics with calculus.

Easy-to-read information and an illustration of an "electromagnet," a type of magnet in which the magnetic field is induced by the flow of an electric current.

Practice identifying the direction of current flow, closed circuits, and open circuits with this multiple choice quiz.

A teacher lesson plan which could be easily converted into an idea for a student project or presentation. Ideal for pre-high school students. This page describes an activity in which the history of electric circuits, the nature of...

Students engage in an interactive "hot potato" demonstration to gain an appreciation for the flow of electrons through a circuit. Students role play the different parts of a simple circuit and send small items representing electrons...
