Benchmark Question: How can we describe and measure
vibrations and waves?
Focus Question: What are the properties of waves?
After a brief discussion
about waves, students working in small groups will produce waves using a
coiled phone cord or Slinky. Students will place the phone cord on the
floor and anchor one end of the phone cord and then oscillate the other end
back and forth across the floor. Students will observe the repeating
patterns of the waves.
Students then will
experiment to increase the height and the number of waves in the cord.
Students will write down their observations and explanations and share them
with the class. At the conclusion of the activity, the teacher will lead a
discussion about frequency, amplitude, wavelength, and energy and relate
them to the observations of the phone cord. In their journals, students
will reflect on how these properties are related.
