Pbs Teachers: Wind Tunnel

Using a teacher-built wind tunnel constructed from a paper concrete tube form, a fan, and a balance, individuals determine the amount of drag their rocket design will experience in flight. Pupils make modifications to increase the...

Design the best from the best. Groups work together to come up with the best configuration of different variables that affect a wind turbine. The teams choose from several variables such as the number of blades, the angle of the blades,...

Students examine how wind tunnels are used for research and development.  In this aerodynamics lesson students are given instructions on how to develop different types of wind tunnel.

Investigate the science of flight, the tilt or angle of attack of a wing's surface and the effect of control surfaces. Construct a model of an open jet wind tunnel using a household desk fan to produce a flow of air.

In this video segment adapted from ZOOM, cast members are challenged to design a windmill that can be powered by a hair dryer. [3:38]

Does the very thing that is responsible for life on Earth also have a dark side? Space scientists differentiate between sunspots, solar flares, and CMEs in an enlightening activity. The lesson, one of several in a unit presented by NOVA,...

In this video segment adapted from ZOOM, visit a class as they design a city of the future that will use solar, wind, and water power to fuel its economy. [2:12]

This video segment adapted from the PBS series "Building Big" shows how a structural engineer overcame the challenges of building New York's Citigroup skyscraper over a church by using triangles to add muscle and stability to the...

View videos and photos from the aftermath of Hurricane Matthew and see how the earth's landforms changed as a result of the heavy winds and rain. Weathering and erosion made a new landform and dramatically changed the coastline....

Explore what meteorologists do. Discover how they use doppler radar to measure the wind speed of a tornado.
