1. Take a clear glass and fill it about 3/4 full of water.

2. Now take a fairly long pencil and hold it in the glass so its straight up and down. (You could hold it in place with a piece of tape.)

3. Look at the pencil through the side of the glass. How does it look? Draw a picture of the pencil in the glass.

4. Now lean the pencil against the side of the glass. Again, observe the pencil through the side of the glass. (Turn the glass so you can see the pencil from a number of angles. What did you observe? Draw a picture of the pencil in the glass.
