Content Standard 5: The Universe – The
universe is an ever-changing system of
matter and energy that exists now, in the
past, and in the future.
1. The stars differ from each other in size,
temperature, & age, but they appear to be made up of the same elements that are found on Earth.

Content Standard 5: The Universe – The
universe is an ever-changing system of
matter and energy that exists now, in the
past, and in the future.
2. All stars have life cycle including birth, development, and death. Fusion reactions in stars release great amounts of energy and matter over millions of years.

Albert Einstein’s famous equation (1915):
E = mc2
E = energy ; m = mass ; c = speed of light
Stars have a high value for density and mass.
