Name _______________________________ Room # ______ Team _________________________ Date _______________ MESSING WITH MOLECULES and ATOMIC MODELING! Part One: Today we will study matter by looking at the smaller units that make up common everyday things. Using the periodic table we should discover elements found in common materials we use everyday! 1. Oxygen = O2 O = _____________ we need _______ atom(s) of it! 2. Water = H2O H = _____________ we need _______ atom(s) of it! O = _____________ we need _______ atom(s) of it! 3. Sodium monofluorophosphate is toothpaste = Na2PO3F Na = _____________ we need _______ atom(s) of it! P = _____________ we need _______ atom(s) of it! O = _____________ we need _______ atom(s) of it! F = _____________ we need _______ atom(s) of it! 4. Baking soda = NaHCO3 Na = _____________ we need _______ atom(s) of it! H = _____________ we need _______ atom(s) of it! C = _____________ we need _______ atom(s) of it! O = _____________ we need _______ atom(s) of it! 5. Bleach is called Sodium Hypochlorite = NaClO Na = _____________ we need _______ atom(s) of it! Cl = _____________ we need _______ atom(s) of it! O = _____________ we need _______ atom(s) of it! Part Two: Today you will have a Reader (reads directions), a Sorter (sorts out materials), a Builder (constructs models) and the Equalizer (splits up materials and bags them up) You will need to work together, if not, you will not be able to take home your Atomic Treasures! Today we will build molecule and atomic structures and calculate the electrons, protons and neutrons! 1. First get jobs. Sort out materials. 2. Reader needs to direct the group, read instructions. 3. Builder constructs, equalizer will clean up materials so all get a fair portion of candy in their after school baggie! Directions: First task. You will need to build two models of carbon dioxide and water using toothpicks and gum drops. CO2 and H2O will need to be made. You must get your models checked off. How many C to O? How many H to O? Pay attention to colors, they represent different atoms! Draw and color your models below! Toothpicks are the bonds made! Look at the board for the hints and help! Part Three: We now look at the smallest unit of matter, the ATOM! Atoms have a + charged particle called a __________________, a – charged particle called an _________________, and the neutron. Directions: So… now we will construct a model. In the nucleus we always put the protons and neutrons; in the electron shells we place electrons! You will need to calculate the electrons and protons using the atomic number. The neutrons are found by subtracting atomic mass from the atomic number! Atom Work: First write out the answers and then place the particles on your diagram. Two electrons fit into the first floor, up to eight in the second floor, and up to eight in the third floor. You will need to separate your candy into three types of particles, the smallest particle is the electron, make sure your smallest candies are representing the electrons! Key: 1. Nerds candy (electrons are super light and small) = E2. Skittles candy = P+ 3. M&M’s candy = N Atom 1 = Helium Protons = ______ Electrons = ______ Neutrons = _____ Drawing: Atom 2 = Neon Protons = ______ Electrons = ______ Neutrons = _____ Drawing: Atom 3 = Boron Protons = ______ Electrons = ______ Neutrons = _____ Drawing: Atom 4 = Oxygen Protons = ______ Electrons = ______ Neutrons = _____ Drawing: Bonus Work for Dollars??? See if you can earn some money… Choose to make some models of other atoms! Get one group sheet for today!
