Lesson focuses on computer and mechanical engineering and explores how computer mice operate and how engineering provided an interface between man and machine.
Simple machines: their principles and uses.
Lesson focuses on the engineering behind big wheels (sometimes called Ferris wheels). Teams of students explore the engineering behind the "London Eye," explore the history of big wheels, and construct a working wheel model using pasta, glue, and teabags.
Lesson focuses on the engineering and operation of artificial heart valves, and the interface between man and machine.
Develop a working model of a nail clipper.
Lesson focuses on brakes, force, and friction, using bicycle rim brakes to demonstrate basic braking mechanisms to stop, slow, or prevent motion.
Demonstrate the concept of rotational equilibrium.
Lesson focuses on the concept of force and the use of pulleys to reduce required force.
Lesson focuses on the concept of friction and the use of ball bearings to reduce friction.
Demonstrate how product design differences can affect the success of a final product -- in this case a bag for holding candy. Students work in pairs to evaluate, design, and build a better candy bag.
