Designing Windmills

Emerging engineers perform pre-lab calculations in this first of a three-part instructional activity on model building. They determine the forces of tension and compression in a truss. After completion of the worksheet, pupils will draw...

Everything from adding an overlay to uploading images to navigating the software, teachers become apt at using Google Earth™ in the classroom to create Earth Science lessons.

Engineering enthusiasts are sure to explode in understanding as they practice the engineering design process (EDP). A container of "toxic popcorn" is placed in the classroom. Teams must work together to devise a method for removing it...

Small groups use information they have learned about blade construction to design, build, and test their own concepts. The teams compete in order to determine which design has the best average power output. 

In this chemistry olympiad laboratory worksheet, learners design and carry out two experiments. They design one experiment to test for the percent mass of a substance in a solution and they design another experiment to identify two...

Build an air lift siphon using your mad physics skills! Learners first investigate the importance of circulating water in aquaponics systems. They then use density to their advantage as they engineer an air lift siphon

By imagining an electron as a particle of dust in a raindrop, the narrator helps viewers to understand wave-particle duality. Drawings and narration liken it to a particle being guided by a wave. The challenge, however, it to determine...

Who says playing around in class is a bad idea? Precocious physicists engage in building mechanisms that include cams, gears, pulleys, and levers using an interactive lesson. After completing toy tutorials about each topic, users build a...

Students work to create a design that will protect an egg from being dropped from a one story floor. They test their prototype after it is completed. They write clear instructions and link aspects of the design process to the scientific...

How can you tell the difference between chemical compounds, when so many of them are white and powdery? The fifth installment in a series of ten videos exposes learners to flame tests and formation of insoluble compounds as methods of...
