Get hands-on in your physical science class by having learners conduct electricity with their own hands! By placing one hand on each of two different metals, a current can be generated and measured on a microammeter. Make an experiement...

Light up someone's day with conductive greeting cards. Scholars design and create greeting cards that include LED lights. Rather than use copper tape, they apply conductive paint or copper paint to create the necessary electric circuits.

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.

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Put those old holiday lights to good use. Individuals use a section of ornamental lights to create electric circuits. If the lights glow, it's a success; otherwise, it's time to try again!

Every time a bell rings ... there is lightning in the area. The activity provides directions to build a model of a lightning detection system. Similar to a system designed by Benjamin Franklin, the system uses static...

Here's an electric lesson on electricity. Pupils create an electric circuit to model a city's electric system. They then test out different materials to see whether they are conductors of electricity.

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

Make electricity flow through Play-Doh. Individuals create animals or other creatures using Play-Doh. The engineering aspect? Eyes that light up and Play-Doh that conducts electricity.

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!

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...

Knead a resource on electric circuits? A fun activity teaches future scientists about conductors and insulators. They prepare conducting and insulating dough and use them to make creatures that light up.

Creatively combine clothes and conductors. Pupils learn how to use conductive thread to make electric circuits. They apply the thread to design and build an accessory item with LEDs.

Using a simple circuit with the battery representing the brain, future physiologists test to see which solutions conduct electrical "nerve impulses." Enlighten learners with plentiful information on electric signals in the nervous system...

Your pupils can build their own electromagnet — awesome! The culminating activity in an eight-part series challenges groups to design and build their own electromagnet. The goal of the activity is to build a magnet capable of picking up...

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

How much energy does it take to light a room? Class members calculate the total wattage it takes to light the classroom. Through calculations, responsible scientists determine the cost of energy for the year, then figure out...

Help your class determine the types of pollutants coming from vehicle exhaust. Groups use an air quality monitor to determine the emissions from different vehicles, to gain knowledge about combustion energy, and to predict how the...

Whose home is it anyway? Design teams plan a housing development in which they must also protect a native species. The teams consist of a project manager, civil engineer, environmental engineer, and graphic designer. Teams present their...

Small groups use rubber bands to accelerate an Android device along a track of books. They collect the acceleration data and analyze it in order to determine the device's velocity. 

Students build their own simple conductivity tester and explore whether given solid materials and solutions are good conductors of electricity.

An experiment where one must first build a conductivity tester, then use it to test how well water conducts electricity when different materials found around the home are each dissolved in it.

Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...
