The 3rd week, Jan-What causes day and night?

Earth rotates toward the east. This causes the Sun to appear to rise in the eastern sky, move across the sky from east to west, and appear to set in the western sky.

Younger children do not iunderstand that Earth's rotation cause night and day. Their common experiences tell them that the Sun, the Moon, and stars seem to ove around Earth. It is difficult to change their perceptions.

The 2nd week, Jan- The Sun

The temperature of the surface of the Sun is 5,778 Kelvin(About 6,000 Centigrade).

That's extremely hot, and gives the Sun's light its yellow color.

If the Sun were any cooler, it would be more of a reddish color.

And if the Sun were hotter, it would look blue.

The Sun is hot enough to give off the white yellow light that we see.

The temperature of the inner core of the Sun is about 15,000,000 Centigrade.

*How to measure the temperature of the Sun?

The big thermometer ?
