calculations/interpretations: show all math performed (label the calculation or give the formula, show your setup, and give the result) and include proper labels. also, answer any questions asked in the lab. 1. show sample calculation used to find average time. 2. show sample calculation used to find velocity (d/t). 3. how did the different stretches (densities) affect the velocity of the pulse? conclusion: begin by stating whether the hypothesis was true or false. use data and calculations to support your answer. consider the following questions as you write your conclusion: why or what happened to result in the outcome you observed? did you learn anything new? if not, what previously concepts did this lab reinforce? is there anything you would or could do differently that would improve the experiment? do you have any other comments/observations you would like to share about this lab? (*note: not all questions pertain to each lab.) your conclusion should be approximately one paragraph in
