Outside Tennis Courts 54 feet wide Gym-- Inside the blue lines 36 feet Name Date Science Class LAB Speed Relay For this lab, you and your group will investigate speed in the form of human body movement. High speed is not the goal here. The goal is to plot speed coordinates, to calculate speed as slope, and to determine a formula that will convert one form of speed (feet per second) into another (miles per hour). Job #1 Student ____________________________________ 1 . Design a relay course for your group on the outside tennis court, or the gym inside the blue lines. Use the diagrams below to plan the length of each leg. NOTE: Each leg must be a different distance. Note: If outside, there will be NO JUMPING OVER THE NETS. 2. Prepare a written plan to me that describes how each person will move (e.g. run, skip), and how long each leg of the relay will be in feet.

Job #2 Student _______________________________________ Develop your relay data into a handwritten distance-time story. Write your hypothesis here about how fast in miles per hour you think that each member will move. 2. Document your team results in story form (use the form on the next page). 3. Complete the point-distance-time table to identify the points at which speed changes in your story. 4. Graph your story, using time on the x-axis, and distance on the y-axis. 5. Write each person’s name on his/her leg of the journey.

Title: _____________________ image: Title: _____________________ . Point Time ( ) x Distance ( ) y

Job #3 Student _______________________________________________________ Calculate the average speed in feet/second for each leg of the relay. Show all work. Convert each average speed into miles per hour. Show all work.

Job #4 Student ______________________________________________ Create a spreadsheet graph with formulas to match your handwritten story. 8. In a spreadsheet program, create a data table based on the point-distance-time table. 9. Insert scatter chart with straight lines and markers. This chart should look like your handwritten graph. 10. Add chart title, axis titles, and data labels. 11. Add a third column to your data table “speed(feet/second).” Type in 0 as the starting speed. Then, in the cell that goes with your name, add a formula to automatically calculate average speed in feet per second. Your results should match your handwritten story. 12. Add a fourth column to your data table called “speed (miles/hour).” type in 0 as the starting speed. Then, in the cell that goes with your name, add a formula to automatically calculate speed in miles per hour. Your results should match your handwritten story. 13. E-mail me your spreadsheet graph with embedded formulas.

Job #5 Student who completed job #1 _______________________________________________ 14. Conclusion: Did your data support your hypothesis or not? Explain. 15. Make a suggestion that would improve this lab. 16. What other speed ideas could be studied as a lab? Job #6 Every Student ___________________________________________________________________ Evaluate this “team” approach to doing a lab. Each person is to list a benefit, and a challenge.
