Summary of clip: The scene opens with a shot of the "first flight out of Germany" that was available for Indiana Jones and his father. The flight is on a zeppelin. The next shot you see is of the zeppelin taking off. Later in the scene, you see the zeppelin turning around and heading back to Germany. This is when Indy and his father decide to make their escape by using the plane attached to the bottom of the zeppelin.

Connection of flickclip to the concept:This clip illustrates the use of buoyancy in a passenger blimp. The zeppelin in the 1930's (which is the time period of this clip) used hydrogen (extremely flamable) and was a source of transportation for many people. Today, we have the Goodyear blimp, which is not a passenger airship.

Suggestions to Teachers:

1. Before watching the clip, the teacher should inform students that this is a 1930's airship.

2. Key questions to ask include :

a. Have students heard of the Hindenburg?

b. What was used to make the Hindenburg airborne?

c. Why was this gas a good choice? Why was it a bad choice?

d. What property does the gas need to have in order to be a good candidate for an airship?

e. What would have been another good gas to use (teacher can give students a list of the densities of several gases).

3. This would be a good time for the teacher to introduce the Archimedes' Principle. The teacher could give students some information regarding the specifications of the airship and ask students to do some calculations:

a. How large would the "blimp" part of the ship need to be in order to lift a set amoutn of weight?
