  • 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. Nuclear Fusion in Stars• Stars such as the sun are basically hot balls of hydrogen and helium gas that emit light.• They are held together by the enormous gravitational forces caused by their own mass.• Inside the core of a star, these forces create a harsh environment, with pressure more than a billion times the atmospheric pressure on Earth.

  • 5. Nuclear Fusion in Stars• Inside the core of a star, these forces create a harsh environment, with pressure more than a billion times the atmospheric pressure on Earth.• The temperature is hotter than 15 million kelvins, and the density is over 150 times greater than that of water. Video No Excuses, Just Results! Show-up, Engage & Produce
  • 6. Nuclear Fusion in Stars• The temperature is hotter than 15 million kelvins, and the density is over 150 times greater than that of water.• In extreme conditions, nuclear fusion reactions combine the nuclei of hydrogen atoms into helium with a release of energy.• This energy flows outward, balancing the inward pull of gravity.
