Students use the thrust produced by falling water to investigate Newton’s Third Law of Motion.
Student teams will construct water-propelled engines out of soft drink cans and investigate ways to increase the action-reaction thrust produced by water shooting out of holes punched in the can sides.
The "Hero Engine" activity is from the Rockets Educators Guide. Although grade levels are suggested, small modifications will enable more complex activities to be used successfully with other grade levels for observation, demonstration or complete lessons.
