    Molecule Project

    Name ________________________________________ Sci ____

Background: Atoms combine so that they can have 8 outer electrons; this is the octet rule. Hydrogen is an exception. Helium, a

    noble gas, is also an exception. A molecule results when two or more atoms share electrons. When atoms bond in this way, it is

    called "Covalent Bonding." All compounds are pure substances and have properties that differ from their component elements!

    A compound is a material formed from elements chemically combined in definite proportions by mass. For example, water is

    formed from chemically bound hydrogen and oxygen. Any pure water sample contains 2 g of hydrogen for every 16 g of oxygen.

    Choose Project 1 or 2

    Project 1 Draw 10 molecules

    Project 2 Draw 5 molecules + write 5 Haiku poems (or other options) for 5 additional molecules Extra Credit Build 1 edible candy molecule (you can build more than one.) Do this at home.

Directions for Drawing 5 or 10 Molecules:

    1) Write the name and formula of each molecule near your drawing. 2) Neatly draw the structure of each molecule. Use color! 3) Make sure that all valence (outer) electrons are clearly visible.

    4) Make sure that all bonds between electrons are straight. No spaghetti lines!

     (You may rotate the electrons around the atom for a better connection.)

    5) Indicate the number of elements that are in the molecule. 6) Indicate the total number of atoms in the molecule.

    7) Use color!

    Guanine = 4 elements and 16 atoms

    Example:

    Name Formula Molecule Element(s) Total atoms

    Hydrogen gas H 1 2 2

     Name Formula

    1) Nitrogen gas (~ 79% of air) N 2

    2) Chlorine gas (poisonous) Cl 2

    3) Oxygen gas (~ 21% of air) O 2

    4) Fluorine gas (poisonous) F 2

    5) Hydrochloric acid (gastric acid) HCl 6) Hydrogen sulfide (rotten egg smell) HS 2

    7) Water HO 2

    8) Silica (in glass and cement) SiO2

    9) Carbon dioxide (breathing out now) CO2

    10) Hydrogen Cyanide (poisonous) HCN 11) Hydrogen peroxide (disinfectant) HO22

    12) Acetylene gas (blow torches) CH 22

    13) Ammonia NH3

    14) Ethylene gas (ripens fruit) CH24

    15) Methane gas (natural gas) CH 4

    16) Formic acid (ant sting) HCOOH (Double bond an O to the C)

    17) Methanol (Wood alcohol) CHOH 3

    18) Vinegar CHCOOH (Double bond an O to the C) 3

    19) Ethanol (alcohol) CHCHOH 3 2

    20) Propane gas (grilling food) CH 38

    21) Isopropyl Alcohol CHCHOH CH 3 3

    Scoring Rubric Per molecule

    Correct Drawings: 5 points

    Color: 1 point

    Identifying Elements: 1 point

    Identifying Atoms: 1 point

    Writing Names & Formulas: 2 points

    See the directions on the back of this sheet for more options.

After 5 drawings … here are other options for the project:

    1) Haiku: Write some poems! Identify the name and formula of the molecule. Explain the structure of the molecule. Indicate the number of elements that are in the molecule. Indicate the total number of atoms in the molecule. You may wish to explain why atoms bond to one another. Include a table near your poem that gives the required information about your molecule. See above.

    5 syllables first

    Seven syllables come next

    5 finish your poem

    2) Create a newspaper article about a molecule in "Molecules Monthly". This article should include a headline, an illustration, and some quotes from the atoms that make up the molecule. Explain the structure of the molecule. Explain why atoms bond to one another. Indicate the number of elements that are in the molecule. Indicate the total number of atoms in the molecule.

    3) Write a letter to someone and explain how a molecule is put together. Explain the structure of the molecule. Explain why atoms bond to one another. Indicate the number of elements that are in the molecule. Indicate the total number of atoms in the

    molecule.

    4) Write a dialogue between all the atoms that make up a molecule. Explain the structure of the molecule. Explain why atoms bond to one another. Indicate the number of elements that are in the molecule. Indicate the total number of atoms in the molecule.

Extra Credit to be completed at home: Edible Molecule: Create a 2-dimensional molecule with 4 or more atoms.

    How to build…

    -Cardboard backing for strength

    -Cover cardboard with Aluminum foil for cleanliness

    -Use edible “glue” (ex: confectioner’s sugar and H0) 2

    -Include a key (Red Gumdrops = Hydrogen, M&Ms = _____, Twizzlers = _____)

    -Cover with plastic wrap to bring in

    -Get creative and be sure to include the following information:

    Name Formula Molecule Element(s) Total atoms

    H Hydrogen gas 1 2 2
