The Moon, Tides, and Seasons

Get into groups of four. In your group you are going to have a discussions. With your partners you are going to answer these questions.

-How long does it take the earth to rotate on its axis once?

-How long does it take for the moon to orbit the earth once?

-How long does it take the earth to orbit the sun once?

-What are ocean tides?

-What causes ocean tides?

-What are seasons?

-What causes seasons?

-Are seasons the same in all parts of the earth?

It is okay if you do not know the answers to some of these questions. If you don't know then guess. You need to have an answer but it is okay to be wrong. We will discuss it together afterwards.

Why do we have seasons Part 1 Is it because of how close we are to the sun?

Why do we have seasons Part 2 is it because of the earth's tilt?

Measurements

Scientists all over the world have all agreed to use the same units of measurement in order to avoid accidents like the one with the mars climate satellite.

The universal measurement system is known as the SI Units. SI stands for international system (the S and I are backwards because the french came up with it and they say Le Système international)

Here are the SI Units

Here is a good SI conversion chart to help you with your conversions

The SI system is very similar to the metric system and uses all of the same prefixes for its measurements.

Here is a chart of metric prefixes
