Windmills have been used for hundreds of years to collect energy from the wind in order to pump water, grind grain, and more recently generate electricity. There are many possible designs for the blades of a wind generator and engineers are always trying new ones. Design and test your own wind generator, then try to improve it by running a small electric motor connected to a voltage sensor.

In this activity, students develop an understanding of how engineers use wind to generate electricity. They will build a model anemometer to better understand and measure wind speed.
Students learn how engineers transform wind energy into electrical energy by building …
Students learn how engineers transform wind energy into electrical energy by building their own miniature wind turbines and measuring the electrical current it produces. They explore how design and position affect the electrical energy production.

From 1900 to 2022, global electricity generation grew remarkably from 66.4 TWh to 29,165 TWh. Fossil fuels maintained a stable share of around 60% throughout this period, while renewables like wind and solar saw rapid growth from the 2000s. The 1960s saw a rise in oil power plants, but energy price shocks in the 1970s shifted focus to natural gas and nuclear generation, with significant investments in gas power plants from the 2000s onward.

Students are introduced to the role of electricity and magnetism as they build speakers. They also explore the properties of magnets, create electromagnets, and determine the directions of magnetic fields. They conduct a scientific experiment and show cause-effect relationships by monitoring changes in the speaker's movement as the amount or the direction of the current change.
