I agree with Musashi that
www.clavius.org should be your starting point to investigate any of the hoax arguments. However, some things to remember with this first argument:
- The quoted temperatures are for the lunar 'noon' and 'night'. The Apollo missions were never there during those times. They all landed during the lunar 'morning' when the sun angle was low and so the solar intensity was much lower per square metre. Ask your classmates whether it is as hot at 8:00am as it is at 1:00pm on a summer's day. Why not? How long does 'morning' last on the moon?
- The only real form of heat transfer on the moon is radiation. Conduction & convection are ineffective in the lunar environment. If you are wrapped in something that reflects the radiation from the sun, you will not heat up as quickly than if you wear something that absorbs the radiation. What were the astronauts wearing? What is it made of, and why? Why is the Lunar Module wrapped in that gold foil stuff?
- Look at the astronauts on the moon. See the 'backpack'? That is a Portable Life Support System, or PLSS. AS well as oxygen, potable water, etc, it contains a funky air conditioning unit. Check out how it works.

Another thing they claim is that in the videos of the lander descending (from inside, looking at the surface) there is no engine noise. Is that attributed to the fact that sound doesnt travel in space? I need some help.

Partly.
What creates most of the sound of a rocket engine on Earth? (Hint: Imagine a large cubic volume of air happily minding its own business, when suddenly someone injects a tight bucketload of very high temperature gas...). How does that sound of a rocket engine reach your ears? Can sound waves be carried through a vacuum? Finally, why were the microphones used by the astronauts referred to as 'throat mikes'?

If anyone can help me with these 2 things, it might help me sway my class away from the Dark Side. Thanks!

Go get 'em!
