Rotation Rotation Rotation

It takes only 8 minutes for the Sun's energy (heat and light) to reach our planet even though it is 92,000,000 miles away! The Sun is our star and even though it looks like the biggest star in the Universe, it is only medium size. Why all this talk about the Sun? The students are learning about the Earth's rotation which causes day and night. We use this to help measure time. So we have been practicing rotating (spinning)(Time: 24 hours) and we will see how this is very different this is from revolving which is the Earth moving around the Sun (Time: 1 year)
