This document provides instructions for a class activity where students will measure their running speed over 10 meters using a stopwatch and meter stick. They will then calculate their speed in meters per second and kilometers per hour to compare to speed measurements of various animals and objects listed in a table, ranging from hair growth to the speed of light. Students are asked to write a paragraph comparing the different means of movement and why their running speed is better or worse than the listed items.

- 1. Warm-Up, 09.01.2009 You are going on a hiking and camping trip. You only have enough space to carry one backpack with you, so space is limited. You must carry certain items with you in order for your trip to be pleasurable. What measurements would be important in your preparation?
- 2. Announcements Nothing to see here folks, move along.
- 3. Today’s ObjectivesSWBAT- Demonstrate their knowledge of the metric system & the methods of science.Begin to recognize the role of physics as a fundamental set of rules for reality.
- 4. Describe the forces that interact to create motion and acceleration.Test #1
- 5. Answer to the best of your ability.Cheating, talking, peaking = auto-0No talking until EVERYBODY FINISHES. If you finish early: read, listen to your ipod quietly or sleep. No redos on tests, only extra-credit.
- 6. Motion (btw motion week = puppy week)
- 7. 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.
