This statement reflects your predicted outcome for the experiment. If I project light rays through (choose one: air, water, glass), then they will refract, or bend, the most. Procedure: Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation. Test variable (independent variable): Outcome variable (dependent variable): Select Intro to begin. Once the simulation loads, you will drag the protractor onto the screen so that the 0 lines up with the dotted line in the center of the screen. You will test all three materials in the bottom, blue half of the screen: air, water, and glass. Record your observations of how the light rays interact as they pass from air, on the top of the screen, through the three materials on the bottom of the screen Data: Record the data from each trial in the data chart below. Be sure to fill in the chart completely. Material Interactions List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen. Evidence Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen. Trial One Air on top Angle: Index of refraction: Air on bottom th do much u made my day
