Who this list is for
Built for 11-year-olds, this string telephone network goes beyond one pair of cups. Three listening stations let a group test how sound changes when cotton twine is taut, loose, or routed between stations.
How to use this list
Set up three work spots with a clipboard, pencil, and sound test recording sheet at each one. Use the ruler to measure cotton twine, the hole punch to prepare six sturdy paper cups, and large metal paper clips to secure the string. Label stations and test phrases on index cards with fine-tip markers, then use masking tape where needed to mark positions.
Common mistakes
Do not expect the network to work with slack cotton twine. Avoid talking at the same time as the listener, since that makes recording results difficult. Keep holes centered and small enough that the paper clips hold securely, and do not pull hard enough to tear the cups.
What is on this list
You will find six sturdy paper cups, 60 feet of cotton twine, six large metal paper clips, masking tape, a hole punch, ruler, scissors, and a pack of fine-tip markers. The list also includes 12 index cards, three pencils, three clipboards, and three sound test recording sheets. Cross off items already in the classroom or craft bin.
When you are done
Compare the three recording sheets and note which setup carried sound most clearly. Untie or clip the twine for storage, recycle damaged cups, and keep labeled index cards with the results.
