As you begin your investigation you will need to pin down some basic terminology and phenomena that you will encounter along the way. During this exploration the entire class will be assigned groups composed of three or four students. Each student will have a specific task as indicated below. The purpose is to gain an understanding of basic wave characteristics and their relationships to each other and the medium through which the wave travels.
We will start with a large group demonstration where you will be introduced to mechanical waves and the basic characteristics of wave motion. Each group will need to pick up the following information before the demonstration:
Wave Question/Prediction/Conclusion sheet
(I) Once you have these materials each group member should write their prediction for each question on their own paper (I). One prediction should be chosen by the group to write on the Question/Prediction/Conclusion sheet. We will begin the demonstration when all groups have finished these predictions. Each person may wish to take notes during the demonstration and the group should definitely have some notes since information provided during the demonstration will not be repeated ad infinitum during the lab.
Once the demonstration is complete your group will be assigned one of the questions to study further as described below.
Each group will consist of two sub-groups - (1) Will be responsible for generating useful wave motion and communicating with the teacher - one or two people. (2) Will be responsible for measuring the wave characteristics - must be two people.
Materials provided for each group:
|- 1.5 m of bulletin board paper||- 1 double slinky||- 1 timer|
