To set up this inquiry, we had each student choose a hula hoop to stand inside to throw from. The same hula hoop remained their throwing home for the duration of class. We first had them explore a number of different throwing styles with a foam frisbee, continually reminding them of the aim which was throwing for distance. They all threw at the same time and on command would run out at the same time to retrieve their frisbee and return back to their throwing home. After experimenting with a number of throwing styles, we asked them the following question, "Which throwing style do you think worked best for you"?
All of the students were able to identify the throwing style that worked best for them. We then had them use only this style again and there was a definite difference in the distance that they threw. Although not all students threw mechanically correct, they were able to identify a type of throw that worked best for them which was what the inquiry was all about. They were given the choice to explore and choose.
The same process was used with balls. A follow up discussion led to the conclusion that you must throw a frisbee and ball differently which was another goal of this inquiry. This lesson really did work well and I recommend it as good way to introduce student led inquiry into throwing.
