Webquest I Task #6

Video 1
1.What is their conclusion?
You don not need wind to keep a flag moving. Less pressure has more movement.  They put  the flag in a vacuum so that there is no pressure.  The flag still will move without atmospheric pressure!
2. Scientifically, why do we get this effect in a vacuum?
Less pressure more more movement

Video 2
1. What pseudoscientific assumptions led to the development of this hoax theory?
Photos are taken in a studio because shadows are not parallel.
2.What real science proved/disproved it?
If he was standing in a shadow of or moon module we would not see him clearly. 
During the testing set, the light source was the sun. They turned off the lights to test the shadows. They used similiar cameras as used on the moon. Shadows are parallel on the recreation. The moon has regalith that reflects light which affects the photos taken on the moon.

Video 3
1. What scientific technique forms the basis of this video?
They bounced a laser off the retroreflectors left by Apollo 15.  They shot a laser to the moon and it reflected back. They went to New Mexico to send the laser.   The light returned exactly at the distance they expected and at the same intensity.
