Many people confuse lunar eclipses and moon phases. In this thread discuss the 2 points below:
1) Why do you think people confuse lunar eclipses and moon phases?
2) How would you help someone understand the key differences between the explanation of lunar eclipses and the explanation of the moon phases? And what are the key aspects of each explanation?

1) I think that people confuse these two things because they are both almost the same thing, but they are really happening on different sides of the earth.
2) This is how I would explain these two different things with the person that was confused: a lunar eclipse is when the moon is in a straight line with the earth and sun, so there is the sun, then the earth, and then the moon is in the earth's shadow. When the new moon phase occurs, the moon is closer to the sun, so that when the moon is facing the earth, we don't see anything. Also, the moon is higher or lower in relation to the earth's atmosphere. The key aspect of each of these things is that when the moon phases occurs, it is natural and happens almost every day of the month, and the moon is on the opposite side of where the lunar eclipse occurs. With the lunar eclipse, the moon's light is getting blocked by the earth's shadow and causes it to not be visible, whatsoever.

I think people confuse lunar eclipses and moon phases because they both happen with the sun, the moon, and the earth. Also they might get confused if they look at a picture that shows the positions of the moon, and the earth in both a eclipse and moon phases, they might look the same.
I would explain to them by maybe showing them a video that demonstrated it more clearly and maybe also show them a different model, one that was easier to understand.

People confuse lunar eclipses and moon phases because the new moon looks like a lunar eclipse, however its not because a new moon is a phase. The new moon is always above or below the earth during rotation and the lunar eclipse is directly in line with the earth, in Earth's shadow.

And what are the key aspects of each explanation? 1-because they are very similar in somes way but also very different. they are very easy to mix up. 2-i would tell them that that the sun gets dark on a solar and the moon gets dark on a lunar |

So the moon is the only thing that has the phases?
So then what are the "steps" in lunar eclipses called?

i think people confuse lunar eclipses and moon phases because when the lunar eclipse begins the moon becomes the same shapes as when it does in moon phases so people often think that it is the same thing

I think people confuse lunar eclipses with moon phases because a lunar eclipse looks very similar to a new moon which is one of the phases of the moon.
A lunar eclipse is when the earth's shadow covers the moon so none of it is lit up by the sun. in a lunar eclipse the Earth is in between the sun and moon so the moon is blocked. Phases of the moon are caused by the angle of the earth moon and sun. people confuse a new moon and lunar eclipse because from earth's point of view it looks like the moon is not lit up at all. A new moon is in between the sun and the earth so half of it is lit up on the side closest to the sun but people on earth can't see that.

1. I think people confuse phases with eclipses because a lunar eclipse looks a lot like a new moon, even though it is not.
2. An eclipse happens when the earth, sun, and moon are in a straight line but not particularly in that order. The moon is normally above the earth and the sun is just shining on parts of it to make it look different, which is a phase. It helps to have a drawing or model when trying to explain this to someone because then they can really visualize it.

I dont understand it's rotaions they say that a new moon is a phase how does the moon turn black |

why dont the sun have phases ?

Both of your questions are fine points, Victor. I'll be interested to see how people answer them? AND i'll add one.
How might the Earth have "phases"?
