The remains of the center of the Supernova star might become a Neutron Star. They are VERY heavy stars. A golf ball size neutron star would weigh 1,000 million tons. The center of a Supernova could become a black hole. A black hole's gravity is so powerful that it swallows the remains of the star and all of its light.
Black holes are like bottomless pits from which nothing escapes.
The students can now make a resource booklet with the above information. The student should illustrate each step, referring to the web site images if necessary. Directions for making booklets Fold 6 sheets of white paper in half to make a 12-page booklet. Fold 1 sheet of construction paper in half for the cover. When copying information about the stars, leave enough room for illustrations.
