Skills lab: A "Moonth" of Phases

Guiding question: What causes the phases of the moon

Skill Focus: Making models, observing, drawing conclusions

Materials
-Floor lamp with a 150-watt bulb (normal flashlight)
-Pencils 
-Plastic foam balls

Analyze and conclude
1) In my model the earth is represented as the big foam ball, the moon as the smaller foam ball and the sun (suns rays) as the flashlight and its brightness.
2) We did four circles around the earth instead of 8 and figured out that you always see have of the moon that's bright or visible
3) Iv done this problem in my notebook. 
4) Iv only seen half of the lighten part of the moon after each turn
5) Once again only half of the surface was lit up while the other half was dark because it was facing the opposite direction. I don't think that the new moon was cause by the eclipse but yet the sun itself. when the suns rays are not on shining on the moon
6)Having the model next to me was a big advantege because i could actually see how this was happening in real life, although an disadvantage of using a model is that it of course isn't accurate enough. But all in all it was a big of a help.
