Though not commonly searched for, this is a vivid demonstration of how a fuse can be blown, or rather, how resistance works in an electric circuit. You will basically set up a circuit with no lights or bells or motors, allowing the wire...

Life as we know it would not be possible without electric transformers, so there are fewer more pertinent topics for your eager young engineers. An astounding amount of background information is provided to help you develop a lecture on...

Light up the solutions. By following a set of directions, pupils build a circuit board with six different circuits. Learners use the circuit board to create a matching activity by connecting the questions to the correct answers via a...

Eat up a resource on using food to power electrical devices. Future engineers first experiment with different fruits and vegetables to determine the amount of electrical energy they provide. Based on the data, they design and create an...

Generate a buzz about circuits. Scholars conduct four activities to learn about electric circuits. They create dance pads that buzz and flash when stepped on, build hidden alarms, design creatures with eyes that flash, and take part in...

It's time to wake up! Young engineers build an electric circuit that will activate an alarm. The use of switches in the circuit is a must—because you don't want the alarm to keep beeping forever!

When you think electric circuits, your pencil probably isn't the thing that comes to mind. A simple experiment lets learners test whether the graphene in pencil lead is a conductor or an insulator. If the LED bulb lights up, a conductor...

Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the lesson, they build a circuit with an orange and then with a banana.

You'll dance for joy at finding a helpful resource. Learners use their knowledge of electric circuits and currents to create a dance pad. Buzzes or flashes should occur when dancers step on the dance pads—a sure sign they have all the...

Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is...

Hang a strip of foil on a stand and form a loop out of it. Then attach the clips of a battery-operated circuit to the loop to see its sides repel each other. This simple demonstration is applicable and easy to add to your lecture on...

Light up a locker for a more festive hallway! Scholars learn about electric currents, LEDs, and switches, then experiment with their own circuits. They use the circuits to design and build locker decorations that light up when turned on...

In pairs, learners build a piezoelectric generator from readily available electric components in the second and final installment of the two-part series. Tapping the piezoelectric element produces enough electricity to light an LED....

Sound the alarm about a great resource. Scholars first build a simple circuit to learn the basics about electric currents. They then design an alarm system in which a buzzer activates when pressure is applied to a doormat.

Groups work together to design a lighthouse, from designing and drawing the wiring diagram, to creating prototypes of the switch and circuit, to envisioning and building a scale model along with a blueprint. By including different...

What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

Light and sound go hand in hand. Pupils set up a system that will emit sound when a laser is directed at a photodiode. Various objects, such as a comb and talcum powder, allow for modulation of the laser beam. Individuals also...

In this audio power amplifier worksheet, students answer five questions about class A amplifiers, sound pressure, crossover distortion, and amplifier design.

This activity will show how to properly connect wires to make a closed electric circuit. Included in this will be how to connect batteries in series and/or in parallel, and how to properly measure potential drops across a resistor and...

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...

Step-by-step illustrated instructions showing how to build a circuit board using everyday materials.

[Free Registration/Login Required] An informational text about electric circuits. A question sheet is available to help students build skills in reading comprehension.

Create your own simple electric circuit. Using simple supplies build your own battery and investigate conductivity. You can also construct a crossword puzzle with electrical vocabulary words.

In the everyday electrical devices we use - calculators, remote controls and cell phones - a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use a battery,...
