Unit 1 Project

Unit 1 Project

Background: With the end of our first unit of chemistry in sight, consider all you have learned thus far.  Our initial review of matter (including mass, volume, and density) led to an introduction of the periodic table.  We learned about the history of atomic models, explored how atoms are constructed (protons, neutrons, and electrons) and how changing those particles impact an atom.  We learned that the elements are born in stars, with heavier elements forged in the explosive forces of supernovae, while unstable atoms experience decay over time.  We learned that neutrons decay into protons, protons decay into neutrons, and atoms can gain or lose electrons according to well-defined rules (main-group elements) and less-well-defined rules (transition metals).  We learned how to assemble ions into compounds, how to identify the metals in ionic compounds using the flame test, and how to write electron configurations of elements according to the number of electrons in subshells.

“The cosmos is within us.  We are made of star stuff.  We are a way for the universe to know itself.”

What does this quote mean to you?  Your assignment for this project is to unpack Carl Sagan’s famous quote, applying what you have learned during chemistry in unit 1 to your own effort to know yourself.

Deliverable: A well-written essay shared with Mr. Swart as a Google Doc.  Incorporate as many Unit 1 vocabulary words as possible (highlight in bold font if you want them to count toward your total!), in a manner that isn’t forced, to demonstrate mastery of the unit and a deep understanding of yourself.  I look forward to learning more about you!

Due Date: Friday, November 8, 2019

  • Chapter 1: What are your intensive and extensive properties? What makes you who you are and you don’t see changing over time (intensive properties)?  How have you changed over time, and what changes do you anticipate for yourself in the future (extensive properties)?
  • Chapter 2: Where does your name come from? What does your name mean to you?  What does your name mean to others?  What symbols best represent who you are and why?  Consider your reactivity: what gets you excited?
  • Chapter 3: Models of the atom have changed over time – just like people!  Think about how well your teacher and classmates know the real you.  How well do you know the real you?  What are your most important parts (your metaphorical protons, neutrons, and electrons).  Share insights about yourself that are not obvious to someone who doesn’t know you well and would like to know you better.  What are your needs (fusion)?  What are your gifts to the world (particles shared through decay – let’s make decay a good thing!)?  What are your hopes and dreams, and how will they positively impact others (fission)?
  • Chapter 4: Electrons are the way atoms interact with each other?  We can predict how an atom will interact with other atoms based on its electron structure.  What about you?  Are you that predictable?  What do you intend to accomplish this year, five years from now, ten years from now?  What do you see as your most likely path when you look to the future?  How about your path if you were an ion, able to clear out or add a few extra electrons and make life really interesting for yourself – if there were no constraints on your future, what would you want to accomplish?

Grading: Your essay will be evaluated as a unit exam, a category that comprises 25% of your semester grade.
