What are the different instruments used by astronomers to gather information
about stars?
B. Developmental Activities

Observe the stars in a clear night sky. Do they appear to twinkle? What makes them
twinkle?
What conclusion you can make about stars?

Distance affects the stars apparent magnitude. Other stars are very far away from
the earth. Although their brightness is greater than that of the sun; we cannot see
them during the daytime. The farther away the star is from the earth, the lesser is
the apparent brightness that we see.
