Machines

Use humor to study simple machines! An engaging set of nine lessons allows learners to explore simple machines, kinetic, and potential energy as they work through cartoon renditions inspired by Rube Goldberg. Choose one or multiple...

The world of compliant mechanisms is only limited by the imagination! The video lesson begins with a comparison between traditional machines and compliant mechanisms. The scientists then explain the advantage of having flexible, bendable...

How do teachers calculate test averages? Viewers learn how to calculate test averages in the fifth installment of an 11-part Math in Science video series. The video consider different situations and grading schemes to calculate weighted...

Young scientists learn the importance of knowing blood types and their compatibility. The instructor in the video explains each type of blood and their antigens and antibodies, and then differentiates between AB blood and Rh blood...

It is plane to see that simple machines help reduce the force needed to perform a task.  This resource introduces three of the simple machines--the inclined plane, the wedge, and the screw, and  the formulas in order to be able...

Sometimes simple machines don't seem so...simple. The video lesson explains the principles of simple machines. Viewers also discover the concept of mechanical advantage and how it affects the forces related to simple machines. 

Scientific method, linear measurements, friction, inertia. Imagine learning scientific vocabulary in an ELA class. Before researching and developing a presentation about simple machines, class members build a common, but decidedly...

A half-hour introductory video on mechanics and the metric system was produced with beginning physicists in mind. Note-taking guides are provided, in addition to a follow-up metric worksheet. For the lab, learners construct paper frogs....

By the end of this section, you will be able to describe different simple machines and to calculate the mechanical advantage.

A Rube Goldberg machine does not really look like it would make work easier. Introduce your class to Rube Goldberg with a resource that shows how his inventions make simple tasks harder to complete.
