A "moonth" of a phase

What causes the phases of the moon?
While doing this experiment, the styrofoam ball represented the earth, the flashlight the sun and the mini styrofoam sphere,the moon. During the experiment we discovered that when the sun is behind the moon it would be a new moon for us, we wouldn't see the moon. When the moon is on the sides of the earth, compared to the sun, we would only see half of the moon, it would be a half moon and finally when the moon is one the opposite side of the earth, compared to the sun, we would see a full moon. You might ask yourself... Was the darkness of a new moon caused by an eclipse? Well the answer is NO, the eclipses and the new moons are totaly different things because, eclipses are when the light of the sun is blocked by the earth so the moon can't receive any of the sun's light. While the new moon is when the sun is behind the moon so people on earth can only see the shadowy part of the moon.
I think that making a model make us see and understand better the phases of the moon. I think that models help us to understand better, especially visual persons, because we can see it ourself with our own eyes. While when somebody only explains it to you you can have problems imagining the correct thing, soo you don't understand. The only negative thing with models is that they can take time and it can take for more that one person to build it. I think that another way to understand better the moon would be using online models, images, or even videos, those take less space and time.

Here are the pictures we took:

Reason for the seasons

Today in science we made a very interesting experiment.The problem was "How does the tilt of the earth'axis affect the light received by earth as it revolves around the sun?". For this experiment we used a phoneboard sphere on a stick with a toothpick on the sphere and a small lamptorch pointing on the phoneboard, we finally used a small gided transparent sheet of plastic. The phoneboard stick was putten into a 23 degree angle and was suppose to represent the earth, the toothpick represented buildings, trees, mountains or other things on earth and the flashlight represented the Sun, the sheet was only used for us to see the amount of sdirect and undirect sunlight on earth. Throughout the experiment we made the sphere rotate, the rotation represented the rotation of the earth, or one earth year. When the shere was closer to the sun it meant that it was summer and when it was the farthest from the sun it meant that it was winter. During this experiment we learned many things as, the shadow in the summer is bigger because there is more direct light on objects.We also saw that the squares ( made by the grided transparent sheet) are the most normal on the equator wich means that there is the most direct sun light. We also discovered why the poles only get few hours of day each day while the countries on the eqautor only have few hours of night each day and that's because the poles get no direct sunlight , while the equator gets almost only direct sunlight.I also learned that...In the summer the grid squares are keeping there shape squared on the equator and therefor the equator never has winter, most of the heat is directed foward.In summer the Grids squares are spread out on the poles, they are rectangular/irregular shaped, there for they only have winter all year long/only a light heat is directed on them.As the earth rotates, because it s tilted, when there is light on the south pole therefor north pole has less sun light and when there is a lot of. Light on the north poles there is much less light on the south pole. When it is summer there is more light on the north poleand when it is winter there is more light the south pole.
By making this expereriment and looking at all of the information we got from it, we concluded that if there was no tilt there would only be autumn and spring,there wouldn't be any extreme as summer and winter.
