There are more stars in the sky than anyone can easily count, but they are not scattered evenly, and they are not all the same in brightness or color.
Learning Goal 2
The sun can be seen only in the daytime, but the moon can be seen sometimes at night and sometimes during the day. The sun, moon, and stars all appear to move slowly across the sky.
Learning Goal 3
The moon looks a little different every day but looks the same again about every four weeks.
For Grades: 3-5
Learning Goal 1
The patterns of stars in the sky stay the same, although they appear to move across the sky nightly, and different stars can be seen in different seasons.
Learning Goal 2
Telescopes magnify the appearance of some distant objects in the sky, including the moon and the planets. The number of stars that can be seen through telescopes is dramatically greater than can be seen by the unaided eye.
Learning Goal 3
Planets change their positions against the background of stars.
Learning Goal 4
The earth is one of several planets that orbit the sun, and the moon orbits around the earth.
Learning Goal 5
Stars are like the sun, some being smaller and some larger, but so far away that they look like points of light.
Learning Goal 6
A large light source at a great distance looks like a small light source that is much closer.
