As part of the unit of work on science MARS ONE GN, the MYP year two science students had fun at the same time they had the opportunity to design, construct water-propelled engines using the ‘hero engine’ as a model to see the effect these variables have on investigate the Newton’s third law of motion using thrust produced by falling water.

This activity simulates the operation of the classic aleoliphile engine invented by Hero
of Alexandria more than 2,000 years ago. It was a spinning copper sphere that was propelled by a thrust produced by a jet of steam. The engine was
an early demonstration of the action-reaction principle (third law of motion) stated by Sir Isaac Newton 1,700 years later.
