Gummy Worm Stretch

This science experiment is a wormy workout.

Ages

5-7


What you need:

  • 4 gummy worm candies, all the same size 
  • ruler 
  • ice cubes 
  • 2 bowls 
  • 2 zip-top baggies 
  • paper 
  • pen or pencil

What to do:

  1. Measure the length of each gummy worm on a ruler. Record the measurements as "length before," and then set aside one worm.
  2. Take the worm you have set aside and stretch it as far as you can without breaking it. Record this measurement as "length after." 
  3. Take a second worm and roll it between your hands for 4 minutes to warm it up. Stretch it along the ruler and record the "length after," noting that this was the hand-warmed worm.
  4. Fill one bowl with hot water and one bowl with ice cubes. Place the two remaining worms in separate baggies and submerge them in the bowls for 4 minutes. Then stretch each worm along the ruler and record the two final lengths.
  5. Compare the results. How does temperature affect how much a gummy worm can stretch?
