Testing+Law+of+Reflection+Activity

__Testing the Law of Reflection__ Purpose: Design an experiment to test the law of reflection according to the scientific method. Your write-up must include and address the six underlined items below. Equipment list: Tight rubber band, marble, ramp, protractor, and paper.

1. Write the law of reflection. The __law of reflection__ states that...

2. Write this posing question. __Posing Question__: Is the law of reflection true?

3. Write a hypothesis. Make a prediction based on the law of reflection. Tell what you expect to happen in your experiment.

4. Describe how the experiment will be done. Tell what will be done with the equipment. Others should be able to read this and do the experiment. __Experimental Design__:

List the following: __Manipulated variable__ – (This is the thing that is changed.) __Responding variable__ – (This is the thing that responds to the change.) __Controlled variables__ – marble speed, ramp height (Factors not being tested that could affect the experiment) __Control__ – marbles will be rolled at different angles (A comparison used to help determine the results of the experiment.)

__5. Collect Data:__ (Making a table.)

__6. Analysis & Conclusion:__ (Tell why your hypothesis was supported or not supported by the data.)
