Lab: Rubber Band Shoot Purpose: If you stretch a rubber band, how far will it fly? Materials: rubber bands, ruler, meter sticks or tape measure Procedure: 1. Measure the length of a rubber band in millimeters; L = mm 2. Stretch the rubber band on a ruler by 10 mm (or 1 cm) in length (L = 10 mm) and release it 3. Measure the distance traveled in cm and record the data in the table 4. Repeat the process, each time stretching the rubber band by 10 mm more 5. Complete the data table 6. graph the data Date Table 1 Total Stretch L + 10 mm L + 20 mm L + 30 mm L + 40 mm L + 50 mm (in mm) Total distance (in cm) Graph the data using a line graph with distance traveled as the dependent variable Analysis: 1. Why did we measure the rubber band without slack? 2. What factors could affect the distance a rubber band shoots? 3. How would thicker rubber bands shoot? 4. How would temperature affect the distance a rubber band shoots? 5. Can you calculate the velocity of the rubber band? How? 6. When does it have potential energy? 7. When does it have kinetic energy? 8. How do PE and KE relate? 9. Finally, write a formula relating distance traveled to amount of stretch (D = S) Process Skills Used: Conclusion
