  3. 3. ACHIEVE South High SchoolActivity • INDEPENDENT STUDENT WORKConversation • Level 2 - soft conversation.Help • Ask neighbor. If he/she doesnt know, then raise your handIntegrity • Do your own work!Effort • Work on task with notebook open.Value • Concepts in notes reinforced.Efficiency • Read instructions. Use notes & examples in notebook.
  4. 4. Formation of stars/sun1. Thin invisible cloud of gas and dust collapsed inward, pulled by the force of its own gravity.2. As the clouds fell together, it began to spin and the smaller the cloud got, the faster it spun.3. The center of the cloud reached a temperature of 15 million kelvins after about 30 million years after the cloud started to collapse. Video No Excuses, Just Results! Show-up, Engage & Produce
  5. 5. Formation of stars/sun3. The center of the cloud reached a temperature of 15 million kelvins after about 30 million years after the cloud started to collapse.4. Under these extreme conditions protons move rapidly, pressed closer together.5. Through the process of fusion, the protons combine with a release of energy.6. The star/sun was born at that moment fusion ignites the stars/sun. Video No Excuses, Just Results! Show-up, Engage & Produce
  6. 6. Balance of Inward and Outward Forces1. The fusion reactions in the core of the stars produce an outward force that prevents the star from collapsing.2. If this outward force is not checked it would make the star expand and eventually disintegrate or explode.3. When stars use up most of its gas due to fusion, it’s mass will decrease and its gravity will weaken. Video No Excuses, Just Results! Show-up, Engage & Produce
  7. 7. Balance of Inward and Outward Forces4. On the other hand the gravity produces an inward force preventing the star from expanding and disintegrating.5. With those two forces evenly balanced, the stars maintain an equilibrium.6. Scientists estimate that the sun has enough fuel to continue nuclear fusion for another 5 billion years.
