  1. Law of Reflection Proof Lab Experimental Design

  2. Law of Reflection Proof Lab Experimental Design

  3. Demonstrate the use of the rubber band, ramp, marble, and angle paper to facilitate imitative and observational learning. (monkey see, monkey do) This also activates the “anticipatory set” while building background knowledge.

  4. The paper lists the six steps of the scientific method. Scientific Method • The Problem or Posing Question • Research • Hypothesis • Experimental Design • Collet Data / data table • Analysis and conclusion

  5. What is the law of reflection? Correctly replace parts of the law of reflection with the following two phrases: The marble’s hitting angle The marble’s bouncing angle

  6. What will the experimenter be changing in this experiment? What part of an experiment is the above called?

  7. What responds to the manipulate variable in this experiment? What part of an experiment is the above called?

  8. If a marble rolls straight into the rubber band with no angle, in what direction do you think it will reflect off the rubber band? A control in an experiment is used for comparison. Could a marble rolled at an angle of zero degrees be used as a control?

  9. Is this experiment testing the effects of the speed or the effects of the angle at which the marble hits the rubber band? Should the speed at which the marble hits the rubber band be controlled in this experiment? What are controlled variables?

  10. What is used to measure the hitting angles and bouncing angles? Which angle is the incident angle and which is the angle of reflection?

  11. A procedure describes how an experiment will be done. Procedures are often a list of steps that must be done in order. • Place the rubber band half a marble width behind the baseline and parallel to it. • Roll the marble down an angle line towards the rubber band. • Observe the marble bounce and use another line to estimate the angle of reflection.

  12. Law of Reflection Proof Use SNB pages 57-59. • Problem:Write it. • Research: Write the law of reflection. • Hypothesis: Make a prediction. Write how you think the hitting angle will compare to the bouncing angle. (marbles will be provided once these items are complete.) Follow the printed guide and complete numbers 4, 5, & 6
