Science lesson on John 1:35-50
Demonstration on Reflection
Vocabulary: Jesus, image, reflect, reflection, relationship
You will need: an adult or friend, a flashlight, a mirror, a pencil, a piece of paper, and a protractor.
1. Shine the flashlight beam into a mirror and observe the light path as it approaches the mirror and again as it moves away from the mirror. This is the way in which you can measure the angle of the light as it approaches and leaves the mirror.
2. With the point of your pencil, touch the mirror at the point where the reflection is occurring. You may need to adjust your pencil so that it is perpendicular to the mirror's surface. You will now measure the angle which is between the pencil and the beam of light hitting the mirror. You will also need to measure the angle between the pencil and the beam of light leaving the mirror.
What happened? You may wish to try having the flashlight beam hit the mirror at different angles. You will need to measure the hitting angle and the reflecting angle for each one. Did you discover the relationship between the two angles?
THE BIG SO-WHAT -
How is my relationship with Jesus like that of the flashlight in the mirror?
What am I supposed to reflect and why?
