EGG BUNGEE

DIRECTIONS

  1. Placeyour egg in the re-sealable plastic bag with one rubber band attached to it. (This rubber band does not count as one of your four rubber bands.)
  1. One group member should hold the meter stick on the floor or table with the 100 centimeter mark on the bottom, closest to the floor or table.
  1. Add one rubber band to your egg.
  1. One group member willhold the egg at the zero mark. Everyone else will get ready to measure the distance the egg drops (the lowest point the egg reaches).
  1. When everyone is ready, drop the egg. Measure the distance of the drop and record it on your student worksheet.
  1. Repeat two more times, recording the distance the egg drops each time.
  1. Calculate the average distance the egg dropped with one rubber band. Do this by adding the distances and dividing by three.
  1. Add a second rubber band to your egg.
  1. Repeat steps 4-7 for two rubber bands.
  1. Do the same thing for three and four rubber bands, completing three trials for each. Record the distance it dropped each time and calculate the average distance.
  1. As you complete your trials, also complete questions 2 and three on your student worksheet.
  1. Create a line graph of your average distances. Title your graph. Label the X-axis Number of Rubber Bands. Label the Y-axis Distance in Centimeters.
  1. Plot the average distance for each number of rubber bands.
  1. Create a line of best fit to predict how many rubber bands you should use for a 150 centimeter drop.
  1. Create your bungee cord based on the number of rubber bands you decided to use from your graph.
  1. When you are complete, bring it to the bungee testing area.
  1. Was your egg bungee successful? How would you change your bungee to make it better?

  1. Draw a diagram of your Egg Bungee in the spaces below. Label where the egg has potential and kinetic energy. Where is there elastic potential energy?
