The purpose of this part of the assignment is for you to visually demonstrate a physics phenomenon and provide a writeup explaining it. You are required to nd or think of a quick demonstration that illustrates a physics principle. This demonstration may involve: . actually showing the phenomenon (e.g., showing a \"broken pencil\" in a glass of water) 0 showing a device that uses a physics principle (e.g., a hand-powered ashlight or a series of standing wave patterns on a guitar string) a a computer simulation, that you create, demonstrating a physics phenomenon (like the ones you have seen in this course-but not covering the same topic in the same way, of course!) a a very good website or websites which show a simulation of the physics principle, a tutorial explaining the key concepts, the basic physics involved, and a quiz which can check understanding of those key concepts. This might require three different websites. The demonstration must be approved by the teacher and be presented to the class, in a discussion, by a short video, or a series of photographs, or a computer simulation, or a series of sketches, or some other suitable format. It should not take more than ve minutes to present. There will be limitations to the number of people permitted to demonstrate each phenomenon. Inform your teacher as soon as you have chosen your demonstration to avoid being disappointed. The short write-up accompanying your visual representation must include: Purpose: What is the demonstration designed to demonstrate? Materials: Include a list and a diagram. Procedure: Outline the steps followed when doing the demonstration. Observations: Tell what the observation should be. (e.g., for the "broken pencil" demonstration: You should notice that the pencil appears to be displaced at the point at which it enters the water.) Analysis: This is the important section where you clearly explain the phenomenon observed. Show your understanding and enable others to understand. Reference: State where the idea for the demonstration came from. It is perfectly acceptable to use a demonstration that you have read about, but you must put the information and explanation in your own words
