Part 1: The Elements: Forged in Stars

i have multiple chemistry assignments due this week, and i am seeking help with this one:

 

Part 1: The Elements: Forged in Stars

Visit The Elements: Forged in Stars( https://kera.pbslearningmedia.org/resource/ess05.sci.ess.eiu.fusion/the-elements-forged-in-stars/#.WPYyF8dlmfU ) and use the background essay and 3-minute video to find the answers to the following questions:

  • How does a star glow?
  • What types of elements are found in stars?
  • What is a supernova?
  • Why does it take so much heat and pressure to create helium and other elements?

 

Part 2: Show What You Know

  • Perform a Web search using terms, such as “stellar nucleosynthesis,” “helium burning,” “carbon burning” and “neon burning,” to locate balanced equations that show the fusion of lighter elements into heavier elements.
  • Write balanced nuclear equations for the formation of five elements whose atomic number is between helium (2) and iron (26).

 

Present your findings for your research for Part I and II in one of the following formats:

  • a web page that will be accessed by middle school students learning about stars
  • a slideshow presentation OR short video that will run at your local science museum in conjunction with an exhibition on the origins of the universe
