Rocket Boat

WHY?

The motion of the rocket boat is created by the water heating up in the tube and hot gas rushes out, creating a forward push by the backward rush of escaping gas. Newton's Third Law of Motion is in operation during this experiment. If a larger rocket boat could be made by your class, there would be a larger visual picture of the object being pushed forward by an equal extent in the opposite direction by the rush of escaping gas.

ASSESSMENT: Can the student communicate what they observed?

four Student is able to communicate that the forward motion of the rocket boat is created by the backward rush of escaping gas. Student is able to describe Newton's Third Law of Motion in relationship to this experiment.

three Student is able to communicate most of why the forward motion of the rocket boat is created by the backward rush of escaping gas. Student is able to describe in part Newton's Third Law of Motion in relationship to this experiment.

two Student is able to communicate some of why the forward motion of the rocket boat is created by the backward rush of escaping gas. Student is able to describe something about Newton's Third Law of Motion in relationship to this experiment.

one Student is able to communicate one part of why the forward motion of the rocket boat is created by the backward rush of escaping gas.
