Observing, Analyzing, Drawing conclusions
Intended Grade Level - 6-8
Objectives
Students will be able to:
Describe basic properties of waves
Explain the relationship between energy, amplitude and frequency of a wave
Demonstrate proficiency in the use of technology to study waves
Activity Description
Students will work in groups of four and use simple materials to generate waves of varying size. By generating waves using their wrist, elbow and shoulder joints, students will be able to draw conclusions about the energy required to generate various sizes of waves. A technology connection is included using digital camera(s) and a movie making computer program. (Windows Movie Maker is suggested, although any movie making program would work.)
Activity Materials
Task Cards (these can be cut out and laminated to save paper and to make them reusable)
10 ft. nylon rope with electrical tape on each end
Stopwatch
Digital Cameras (if only one is available, it can be used by teacher or just one group)
Computer Lab with computer for each group
Activity Management Suggestions
Students should be placed in groups of four and should each choose one of the jobs on the task cards. Be sure that each student knows the job he or she is responsible for and remind students that in order for their group to be successful, each person needs to contribute.
