Subject: Help me define my main objective for a specific lesson plan.

I am preparing a lesson for k/1 grade level students on energy and motion 
(physical science) using an exercise trampoline and graphing/measuring what 
position causes us to jump higher and why. Inquiry and observation are used to 
develop conclusion. Each student is given opportunity to jump 5 different ways 
on trampoline (students decided together what 5 ways to jump). We measured and 
graphed each jump to determine which position made us go higher. My motive was 
to allow student to explore abilities of their bodies in motion but I have a 
mental block about what specific science objective using energy and motion I am 
trying to teach and can't conclude the experiment in good concious without 
addressing the specific science objective. Can you help? Thanks.
