Science Is A Breeze: Using Wind Tunnels

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...

There has been a huge solar energy spill! Let's go outside to play in it. This lesson includes multiple experiments showcasing solar and wind energies. Scholars build a solar heater and an anemometer before testing the results. The...

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or not. 

When earth scientists or mini meteorologists are learning about wind, they can participate in an engineering activity in which they will design and construct an anemometer. A thorough overview of different types of anemometers is...

The 20th activity in a 21-part series connects the wind data and expectations of a turbine to whether such devices should be built in your area. Scholars begin with estimating the wind potential at school by using long-term climate data...

Teams design and build a windmill, under budget, that can lift an object. The groups evaluate and reflect on their own design, then on those produced by other teams. The goal is to determine which design is the most...

One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...

Learners consider wind tunnels and their importance in the development of flight. Through computer animation, they examine and observe the parts of a wind tunnel. Students evaluate the concept of lift and drag. They build a wind...

An impressive animation explains the earth's awe-inspiring auroras. The contributions of high-energy particles from the sun collide with our neutral atmospheric atoms. Explained are the roles of solar wind, plasma, the magnetosphere,...

Physics learners read a case study about Scott Eberhardt, a scientist who is testing small aircraft in a wind tunnel, but is running into difficulties. They stop at various points to discuss possible solutions to the measurement mystery....
