Week 4 - Matter (Part 4)

Introduction to Matter

Learning Target: I can explore how atoms are joined together in molecules, compounds, pure substances, and mixtures.

Warm-Up (09/03/20)

  • Which type of molecule CANNOT be classified as a compound?
  • What type of bond do you have with your friends or your significant other right now? A covalent bond or an ionic bond? Why? Be creative!
  • If I break one bond in a molecule how does that change the molecule?

IF YOU FINISH: STUDY THE VOCABULARY FOR YOUR QUIZ!

Vocabulary Word Wall


Matter - anything that has mass and takes up space Mass - in physics, the quantity of matter Atom - the smallest unit of an element that maintains the chemical properties of that element Element - a substance whose atoms all have the same number of protonsSubstance - matter which has a specific composition and specific propertiesMolecule - two or more elements joined together by a bondCompound - a substance composed of two or more different elements Chemical Formula - a combination of symbols and numbers that show the ratio of particular atoms within a moleculeSubscript - the number of particular atoms within a molecule Chemical Bond - The joining of atoms by attraction to each other through sharing and exchanging electronsCovalent bond - atoms joined by sharing electronsIonic bond - atoms joined by donating an electronPure substance - a sample of matter with a constant composition and distinct chemical properties

Activity - Molecule draw project

PUT YOUR FULL NAME ON YOUR WORK!

  • Research online and select a simple molecule. (It MUST be a compound)
  • Label the molecule
  • Draw the molecule using a ball and stick model. The drawing must fill the page.
  • Identify the elements within the molecule. They must be color coded with a COLOR KEY. Each element must be one color so if you have more than one Hydrogen all your Hydrogens must be one color.
  • MAKE SURE that the larger elements are drawn bigger than the smaller ones.
  • Write the chemical formula for your molecule with subscripts.
  • Write the ratio of elements within the molecule to each other.
  • Bonus points will be given for adding artistic flair (like today's science joke) and for adding valence electrons. The top 5 drawings will be posted and have a chance to shoot for a snack or rock!
