This video depicts the basic setup and procedure of the guided inquiry phase of the "Seismograph Investigation" lesson plan.
During the procedure, a basketball is dropped from various heights, and a seismograph (smartphone) with special software records the intensity of vibrations in all three dimensions.
The table provides the medium through which the "seismic waves" travel.
After students complete this phase of the investigation, they are given the opportunity to make modifications of this design to test "seismic waves" in other novel situations.
