The Moon: Tides and Eclipses

Today we took the first part of the period to make corrections on the seasons lab. From what had been turned in, it seemed that the majority of you were still a bit hazy on the details of it. We reviewed the main concepts about how the seasons are formed by the Earth-Moon-Sun system, what a solstice is, etc. The grades are now in the gradebook and it seems that everyone is picking up on it a lot better.

We then started to talk about the Earth-Moon-Sun system in its relation with the tides of the ocean and eclipses. You guys took home a worksheet to complete for homework on the subject. This is the worksheet that was handed out:
