Household Energy Conservation and Efficiency
Are your household devices eating up a lot of energy? Pupils investigate household energy efficiency through a set of activities. They find ways to improve energy efficiency and reduce consumption. This is the 21st installment of a...
Curated OER
The Technology of Light
Students study the different types of light bulbs. In this exploratory lesson plan students complete several activities and create an electrical circuit.
Curated OER
Systems and Control
Students create a circuit board that demonstrates how a traffic light works. After writing a PIC program for traffic lights, students assemble a circuit board to test the validity of the program they have written. Circuit boards and...

Teach Engineering: Light vs. Heat Bulbs
Students measure the light output and temperature (as a measure of heat output) for three types of light bulbs to identify why some light bulbs are more efficient (more light with less energy) than others.

Creative Science Centre: Two Low Power Led Flashers
Explains the design of two circuits that can flash an LED from a single 1.5V battery. A typical LED needs 2-3V to work properly and both these circuits include a voltage doubler to boost the voltage to drive the LED. Both circuits will...

Creative Science Centre: Diode Ladder Voltage Multipliers
Explains the design of circuits that can be used to multiply and rectify AC voltages, e.g., to increase voltage in order to light an LED more effectively and get a brighter light from it.
