Explore circuits and the flow of electricity by creating a communication device with a cell battery and electrical buzzer.

Electric circuits are used to provide a path to electric current. They commonly use three basic electrical components, which are resistors, capacitors, and insulators. They affect the electric current and changes the behavior of the...

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. These...

Based off of the hit television show NUMB3RS, this "simple" lesson will actually give students a lot to think about. Given a graph, students are to establish how many searchers are needed to find an infinitely fast criminal who is on the...

Young scholars work in teams to learn about solar panel design, simple circuits, and how solar energy is used to provide power to simple machines such as calculators.

Two teachers approached the technological systems component of the curriculum through a "simple is best" strategy. By the end of the unit, their students had used simple circuits to develop their understanding of technological systems...

Lesson investigates electronic communication from the Morse Code system to text messaging. To learn about this, students construct simple circuits, send messages to each other, and explore the history and impact of communication.

Young scholars took what they had learned and created a matching game (simple circuit board) for others to test their knowledge about energy. The matching game illuminates a light bulb, when the correct matching pairs are selected.

[Free Registration/Login may be required to access all resource tools.] The definition of electric current is explained and how to calculate an electric current. Includes links to resources for learning more about electricity, i.e., a...

Manipulate the voltage and resistance for a simple circuit to see how these affect the amount of current. The symbols in the Ohm's Law equation grow bigger and smaller to emphasize the changes.

Learners construct a simple electrical circuit using wires, batteries, and a lightbulb. From constructing a circuit the students will discover that when energy is produced there is heat.

Everyday we are surrounded by circuits that use "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are composed of many simpler parallel and series circuits. During this activity, students build a simple...

An interactive example of an NPN transistor CE amplifier circuit, a relatively simple amplifier (as far as amplifiers go), which allows the viewer to change input parameters and see how it affects the circuit output. The site also...

Students will learn about simple electric circuits as they investigate the structure of a light bulb and how electricity flows through it.

Simulate the creation of an induced magnetic field through the use of a simple electric circuit. An interactive demonstration is included.

The purpose of this activity is to test the conductivity of various minerals with a simple electrical circuit and draw conclusions about which ones would be used in electronics.

Aldrin saw a broken-off circuit breaker switch lying on the floor of the lunar module and "gulped hard." Following the Apollo 11 historic July 20, 1969, moonwalk, Aldrin and Neil Armstrong were preparing to return to command from their...

Students learn about current electricity and necessary conditions for the existence of an electric current. Students construct a simple electric circuit and a galvanic cell to help them understand voltage, current and resistance.

There are so many different types of LEDs on the market (even of the same size and color), how do you tell the difference between them and which one you should use for your particular application? The simple tests descibed here compare...

Find a review of many aspects of the physical world. Simple explanations of electricity, gravity, and the solar system. Included are materials for teachers to use for enrichment.

An absorption wavemeter is a device which can make measurements on the strength of radio emissions and so this instrument is an essential item for investigating the mobile phone. In principle an absorption meter is a simple device that...
