The Stick That Comes Back
WHY? question_guy
The boomerang is such a simple device and yet it relies on complex aerodynamics and physics. Thanks to our understanding of the boomerang, more shapes have been explored. The duration of flight is determined by the force with which it was thrown as well as the spin applied at launch. As with anything flying through the air, a boomerang is subject to drag and its own weight. The drag slows the boomerang down, thereby limiting the flight time. However, given enough spin and initial velocity, the boomerang might circle above the throwers head a few times before landing.
ASSESSMENT: Can the student communicate what they observed?

four Student is able to communicate how a boomerang is able to return to its sender when properly thrown, explaining the aerodynamics and physics involved.

three Student is able to communicate most of the reasons how a boomerang is able to return to its sender when properly thrown, explaining the aerodynamics and physics involved.

two Student is able to communicate some of the reasons how a boomerang is able to return to its sender when properly thrown, explaining the aerodynamics and physics involved.

one Student is able to communicate one of the reasons how a boomerang is able to return to its sender when properly thrown, explaining the aerodynamics and physics involved.
