1 How Does Light Move? Name: Class: Date: Group Members: Station #1 Checklist Did you draw both diagrams? (2) Did you explain why this happened? (1) Station #2 Checklist Did you draw the diagram with the concave mirror? (2) Did you draw the diagram with the convex mirror? (2) Station #3 Checklist Did you draw the diagram of the light hitting the mirror? (2) Station #4 Checklist Did you indicate the water line? (1) Did you draw the draw the rays to indicate the light s path?(1) Station #5 Checklist Did you draw the first diagram? (2) Did you complete the fill-in-the-blanks in step one? (1) Did you draw the second diagram? (2) Did you draw the third diagram? (2) Did you complete the fill-in-the-blanks in steps 2 and 3? (1)
2 Introduction to Light and Optical Instruments Station #1 Prediction: What will happen to the light rays (numbered 1,2,3) when they pass through glass? (1) Directions: Place a petri dish in front of a ray box - approximately 10 cm away. Draw the rays from the box and beyond the petri dish. Now add water to the petri dish. Prediction: What will happen to the light rays (numbered 1,2,3) when they pass through water? (1) Draw the rays from the box and beyond the petri dish. Record your observations.
3 Can you take an educated guess as to why this happened? Station #2 Directions: Trace the path of light as it passes through a concave and a convex lens. Prediction: What will happen to the light rays (numbered 1,2,3) when they collide with a double concave lens? (1) Place a concave piece of glass 10 cm away from a ray box. Describe and draw what is happening to the light rays and the dispersion of rays. Record your observations. Prediction: What will happen to the light rays (numbered 1,2,3) when they collide with a convex lens? (1) Place a convex piece of glass 10 cm away from a ray box. Describe and draw what happens to the rays as they pass through the glass.
4 Record your observations. Station #3 Directions: Place a ray box in front of a mirror (plane). Prediction: What will happen to the light rays (numbered 1,2,3) when they collide with a plane (flat) mirror? (1) Describe what happens to light as it hits the mirror. Draw a picture of the light hitting the mirror. Record your observations. Station # 4: The Reappearing Coin Observing Refraction Directions: 1) Working with your group, one person is to place a coin in the middle of the empty container. Look down on the coin with one eye, and then lower your head until the edge of the cup blocks your view of the coin. Do not move your head. 2) One person from your group now slowly pours water into the cup until you can see the coin again. If the coin moves because of the flow of water, start again. Use a pen or pencil to temporarily hold the coin in place. All members of the group should observe the coin as water is poured into the container.
5 3) Wipe up any spills and wash your hands after this activity. What did you find out? When water was poured into the cup, you could see the coin, even though the straight-line path of the light was blocked by the cup. On the diagram below, indicate the water line, and draw rays to show the light s path. What happened to the rays of light when light passed from air to water? Station 5: When Light Refracts Directions: Lay the pencil on the desk so that the middle of the pencil touches the back edge of the beaker. Look at the pencil through the front of the cup. Draw and label what you see.
6 Use the following words to fill in the blanks below: bent, water, air. Light from the ends of the pencil travelled only through the. Light from the middle of the pencil travelled through, air,, and then air again. Light did not travel in a straight line. We know this because the middle part of the pencil appeared. Lean the pencil, pointed end down, in the beaker of water, lower your eyes so that they are level with the surface of the water. Draw and label what you see. Look straight down along the pencil that is standing in the water. Move your head slightly to the side. Draw and label the pencil as it appears to you..
7 Use the following words to fill in the blanks below: changes, bent (2), three, straight, air (2), water (2), glass. *NOTE: If a number appears after the word, it means the word can be used that many times. Light from the bottom part of the pencil first travels through and then through. The path of the light was not. When the light travelled from air to the water and from the water to the air it was, which caused the pencil to look as if it were broken at the surface between the water and the air. The light travels through media during refraction in this activity. The path of light during refraction. The image seems (distorted or broken) compared to the real object. Wipe up any spills and wash your hands after this activity.
