This is an experiment which tests different types of containers to see which ones work best as telephones. It involves making different string telephones and testing them out.
It includes some teacher notes, a scientific method chart, the directions for making the telephones, the experiment and the worksheets to accompany it, and a followup worksheet.
The telephones are fun to use later for free time activities as well.
