Summary of clip: Ben Gates, Riley Poole and Abigail Chase are trying to solve the legend of the Knight Templar Treasure, the greatest fortune known to man. In this scene Ben uses a bottle of water like a magnifying glass to read the tiny clock drawn on the back of a one hundred dollar bill to see what time it reads.

Connection of flickclip to the concept: Simple properties of water. This clip shows how to use water as a magnifier.

Suggestions to Teachers:

1. Discuss how they think water can be used as a magnifier.

2. Present students with these materials and have them create their own lab to use water as a magnifier. They must have repeatable procedures and proof that their magnifier worked (i.e. they can show the class their experiment):

a. Plastic wrap

b. Washer

c. Paper with writing on it

d. Water

e. Medicine dropper

f. Straw

g. Sugar

h. Salt

i. Photo of fingerprints

3. After each group is done. Ask what their procedures were, what did they do?

4. Were all the groups' procedures the same?

5. Did they all get to the same outcome?

6. Final Question: How can a drop of water make things look bigger?

Answer: As light enters the drop of water, it slows down. If the surface of the water is curved, the light is also bent into a new path. The rounded shape of the drop bends the light outwards. As the light spreads out, the image that you see gets larger.
