Launch Lab: Running SpeedStep 1) Form into groups of two.Step 2) One person gets a meter stick.Step 3) Make sure somebody in your group/area has a stop watch, a sheet of paper, and a pen in addition to your meter stick.Step 4) Mark off a 10m line on the ground with a starting and ending point. Do not draw the entire line, just place the starting and ending points.Step 5) Have your partner use their stopwatch to determine how fast you run the ten meters.Step 6) Write down your run time.Step 7) Divide 10m by your run time in seconds to calculate your speed in m/sStep 8) Multiply your answer by 3.6 to determine your speed in km/h.Step 9) Compare your speed against the things listed on the next slide. Write a paragraph comparing and contrasting the various means of movement these different things employ, and why or why not this contributes to you doing better or worse than them.
