The document describes a virtual field trip to Hoover Dam, including taking an elevator 50 stories down in 6 seconds to see the large tunnels used to divert water during construction. It explains how water rushing through turbines inside the dam causes them to spin and generate electricity, powering Nevada and Southern California.

1. Hoover Dam
Virtual Field Trip

4. Take elevator going down
 The elevator holds close
to 60 people and takes
you down 50 stories.
Wow!
 It only takes 6 seconds to
reach the bottom.
 When you get to the
bottom you walk through
dark tunnels like the one
on the left.

5. So that’s how they did it!
 This diagram shows
exactly how the Hoover
Dam was constructed.
 Four large tunnels were
used to carry the water
away from the site where
the Hoover Dam was
going to be built. Today
they are used as an
emergency precaution if
lake mead was to flood.

8. Let there be Light
 These are called turbines.
Water rushing through
openings in the dam
causes huge machines to
spin. The spinning
turbines create electricity.
This electricity is sold to
help pay for the dam.
 Did you know these 17
turbines power all of
Nevada and the Southern
part of California!

20. I’m in Nevada and Arizona!
