Refreshed with an understanding of the six simple machines; screw, wedge, pully, incline plane, wheel and axle, and lever, student groups receive materials and an allotted amount of time to act as mechanical engineers to design and create machines that can complete specified tasks. For the competition, they choose from pre-determined goal options such as: 1) dumping goldfish into a bowl, 2) popping a balloon, or 3) dropping mint candies into soda pop (creating a fizzy reaction). Students…

This set of virtual experiments ask students to explore load and effort forces, calculate mechanical advantage and discover the relationship between the number of pulleys, length of rope and the force needed to lift a mass.
