This week we learned alot. We learned more about moon phases, gibbons, crescent, full moon, new moon and quarter half moon. We took a quiz and I think I did good on it. If the earth dissapeerded the moon would go in a straight line. Circular motion stuff. We did a presentation but I could't put it on this. The paper has air resistance. One point of paper is almost no mass and one point on book is heavy.
