I believe the phases of the moon are caused by the moons position and the moon going around the earth. I say this becuase we have already tested the 1st idea and that wouldn't work becuase it would create an eclipse. An eclipse does not affect the moon phases in any way.

I agree with number two. We experimented the things in class and we proved that #2 works.

The second one makes the most sense, because the first one won't work because if the earth cast a shadow it wouldn't cause a half moon because the "edge" of the moon would be curved and not straight like it is.

In class you have been discussing the phases of the moon. The two most common answers Mr. Kruse and I have heard are: 1) The phases are caused by the shadow of the earth which blocks part of the moon from being seen. 2) The phases are caused by the moon going around the earth and the change in moon position changes how much of the moon we see lit up. Which idea makes the most sense to you and what evidence do you have to support your idea? I think that the second idea makes the most sense. I think this makes since because we have been doing a lot of models on how the moon's phases are caused, and this result (number 2) has come up everytime. When we did one of these models yesterday, we concluded that you can see different phases only when the moon is going around the earth because of the way that the sun's light is projected onto the moon. We tested the first idea in class, and we concluded that it is not possible. This is because the rotation of both the earth and moon are different in relation to the sun. Also, when this first idea occurs, it is not a phase, but an eclipse.

I think the second idea makes the most sense because what you see of the moon as it rotates around the earth, all depends of the angle of the sun, moon, and the earth.

i think it is where you see the moon or where the moon is placed and where the sun is placed. sometimes the moon is almost below the earth and sometimes its above the earth.

Mr. kruses class thinks the way that the moon is lined up with the earth causes the phases of the moon.

how the sun is positioned with the moon effects the phases too
