BIG IDEAS:
In this lesson, students model the apparent movement of stars across the night sky to describe why stars are visible at night, but not during the daytime. They focus on the crosscutting concept of Patterns when they describe how the movement of stars across the sky repeats night after night. They also engage with the crosscutting concept of Cause and Effect when they explain the reason for this apparent movement, and why stars are not visible by day. |

Here are some video's you can watch!!
How Many stars can we see from Earth? How many stars are in the universe? | Why do stars appear to twinkle? Do stars move at night or do they just look like it? |
This short video shows star trails being made. It is a permanently mounted video camera that is constantly taking pictures in order to create "trails" as the stars appear to move across the sky. | This short video will show you that the earth is what moves (spins), not the stars in the sky. Each video camera has a "clock drive mount" on it that moves at the exact same rate of speed as the earth turns! |
Notes From Video(s)
