A graphic organizer is a tool or framework that allows you to collect, relate, and/or present information visually. Information presented in an easy-to-read format can enhance thinking, spark new ideas, and maintain focus on the topic or task at hand.

Life as we know it wouldn’t exist without the Sun. This ball of gas emits huge amounts of radiation that has sustained life on Earth for millions of years, and it is categorized as a star. The following activities will introduce students to the cycles of main sequence and massive stars as well as nuclear fusion reactions.
The cycle layout is an option that gives users the ability to show sequences or processes that often repeat, but do not necessarily have to. Depending on how many steps there are to the cycle that you are showing, you can add as many cells as you need.
A nebula is a cloud of dust and gas that collapses under its own weight. As the cloud collapses, it gets warmer. When it reaches a certain temperature, nuclear fusion starts.
At this stage, the outward pressure caused by nuclear fusion is balanced by the force of gravity holding the star together. The energy created by the nuclear fusion is emitted as radiation.
When the star has used up its nuclear fuel (hydrogen), the star grows in size and the outer layers cool, making the star red.
These are some of the most beautiful objects that can be observed in the night sky. A planetary nebula occurs when the outer layers of the star are lost when moving from a red giant to a white dwarf.
A white dwarf is a hot, small, dense, dead star. This is the core of a star that remains after the outer layers have drifted off in the planetary nebula.
After a long period of time, the hot, dense core known as a white dwarf cools and stops radiating light.
