During this activity, students create a working radio by soldering circuit components supplied from an AM radio kit. Since this activity is carried out in conjunction with the associated lessons concerning circuits and how an AM radio works, students should be able to identify each circuit component they are soldering, as well as how their placement causes the radio to work. Besides reinforcing concepts from the lessons, this activity will also teach students how to solder. Soldering is an activity that many engineers perform regularly; by teaching students how to solder, they are able to engage in a real engineering activity.

In this simulation you will investigate relationships between voltage, resistance, and current that exists in an electric circuit. You will adjust voltage of the power source and resistance of the resistor and then use digital multimeter to obtain measurements. Then you will record these measurements and look for relationships that exist between voltage, resistance, and current.
Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

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 series circuit and discover the properties associated with series circuits.

Students investigate circuits and their components by building a basic thermostat. They learn why key parts are necessary for the circuit to function, and alter the circuit to optimize the thermostat temperature range. They also gain an awareness of how electrical engineers design circuits for the countless electronic products in our world.

An extended analogy comparing electricity to flowing water, to help students develop a more intuitive understanding of the components of electrical circuits.
This module provides examples of the elementary circuit elements; the resistor, the capacitor, and the inductor, which provide linear relationships between voltage and current.
Through an introduction to the design of lighting systems and the electromagnetic spectrum, students learn about the concept of daylighting as well as two types of light bulbs (lamps) often used in energy-efficient lighting design.
