Artificial Hearing
Your sense of hearing depends upon tiny hairs deep inside your ear and if you lose these hairs, you lose your hearing. Here, groups explore hearing through the decibel measurement of common sounds. As a class, participants discuss...

First You See It, Then You Hear It
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...

Discovering Ohm's Law
Connect math with science! Pupils apply properties of Ohms Law as they solve problems and identify the inverse relationship of a function. They analyze the shape of the graph of an inverse function and use it to make predictions.
Curated OER
Adventures in Electrical Engineering
Students explore electricity by conducting a series of experiments. In this physics lesson, students discover the relationship between current, voltage and resistance. They calculate voltage and power in a given system.
Curated OER
Semiconductors
Learners investigate the properites of a semiconductor device known as a diode. They recognize a diode as a one way conducting device. They describe alternating current and the use of a diode to convert it to direct current. Students...

From Playing with Electronics to Data Analysis
Pupils collect and Analyze data. In this statistics lesson, students identify the line of best fit of the graph. They classify lines as having positive, negative and no correlation.
Curated OER
Maximum Power Point
Students investigate how to optimize the power output of a photovoltaic cell using a home-made gnomon stand. They use data collected to create current-voltage and power-voltage curves to determine the "maximum PowerPoint," (MPP) at which...
