Students model, build, and draw diagrams of electric circuits and test the conductivity of a variety of materials.
Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone of the popular simulation of the same name marketed by Physics Academic Software and written by Prof. Ruth Chabay of the Dept of Physics at North Carolina State University.

Play ball! Add charges to the Field of Dreams and see how they react to the electric field. Turn on a background electric field and adjust the direction and magnitude. (Kevin Costner not included).
Students will identify some of the differences between the energy sources of electric vs fossil fuel cars. Students will test car design and solar panels to find the best angle to attach the solar panel to the car.
Electric potential difference causes electric charges to move from one battery terminal, through the wire, to the other battery terminal.
When charges flow through a wire or other material, an electric current is created. Electric current involves the flow of charges.
If a short circuit occurs, the charge could flow into the shell of the appliance and the appliance could shock someone touching it.
In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic. Then, they observe as tiny bits of Styrofoam, spices, ceiling glitter, or rice (aka "fleas") jump up to the plastic and then back down.
If a proton and electron come close, they attract each other.
An electrical charge occurs as the opposite charges attract between the bottom of the cloud and the ground below. The lightning bolt we see is an example of electrical discharge.
Inside a large storm cloud, water droplets and other particles are moving around very quickly, creating static electricity.
This is a very simple overview and lesson on electricity. This lesson can be altered to fit the need of your class. Use the pieces that work for you.
The aim of this lesson is to introduce the concepts of Electrochemistry and Electroplating and to present their applications in our daily lives. Students are encouraged to construct their knowledge of Electroplating through brainstorming sessions, experiments and discussions. This video lesson presents a series of stories related to Electroplating and begins with a story about house gates as an example of the common items related to the Electroplating topic. Prerequisites for this lesson are knowledge of the basic concepts of electrolysis and chemical equations. The lesson will take about 60 minutes to complete, but you may want to divide the lesson into two classes if the activities require more time.
Students will investigate the characteristics of electromagnetism and then use what they learn to plan and conduct an experiment on electromagnets.
An electric motor consists of a coil of wire, called an armature, which is attached to a shaft that spins between the poles of a magnet. As electric current flows through the coiled wire, the magnet pushes one side of the coil up and the other side down.
This is a description of a student experiment that teachers can adapt to allow students to prove that electric current produces a magnetic field. The sample includes a specific example of how to do the experiment which can be adapted to an inquiry investigation by having students complete the initial experiment and then write their investigation question and further investigate the phenomena. When completing this as a demonstration or student experiment batteries can be substituted for the variable power supply if power supplies are not available or convenient to use. The voltage provided to the circuit can be easily manipulated by changing the number of batteries connected.
A galvanometer consists of a coil of wire wrapped around a piece of iron that is connected to a needle. This coil of wire spins between the poles of a magnet. When connected to a circuit, the current flows through the wire of the magnetic field.
Model of generator powered by water. The water turns the turbine, which spins the crank shaft that is connected to this wheel of magnets. Coils of wire surround the electromagnets. The electromagnets induce a current in the surrounding coil of wire.
Depicts lines of magnetic force around a current-carrying wire. Electric current flowing through a wire produces a magnetic field. The lines of magnetic force are in a circular shape around the wire.
