Mazapan G.A.N.A.G. Lesson Plan Week of 9/23-27/2013

Standard
(Aligned to Texas Essential Knowledge and Skills) / Goal / Access Prior Knowledge / New Information / Apply Knowledge / Generalize/ Goal Review/ Grade
Monday / Focus Standard:
C.7C: Construct electron dot fomulas to illustrate covalent bondsC.7E: predict molecular structure for molecules…
C.8B: use the mole concept to calculate the number of atoms, ions, or molecules in a sample of
material. / Assessment – Bonding Exam (Part II – Covalent Compounds/Molecular Geometry) / Revisiting the Mole (covered by this group at the very end of last year) – The mole is a counting number (like a dozen) / Demonstrate how to calculate the # of atoms, ions, or moles in a given mass of a single element (dimensional analysis) (3) / Students complete “Introduction to Moles” worksheet – converting between mass, atoms, and moles using dimensional analysis (5) / Assessment – Bonding Exam (Part II – Covalent Compounds/Molecular Geometry
Tuesday / Focus Standard:
C.8B: use the mole concept to calculate the number of atoms, ions, or molecules in a sample of
material. / Students will calculate the molar mass of a compound and determine the number of moles in a given sample of salt. / Molar masses of single elements are used to determine molar masses of compounds / Demonstrate how to calculate the molar mass of a compound by adding the molar masses of all the elements in the compound together (3, 6) / Students find the mass of a given sample of salt and use the molar mass of NaCl to determine the number of moles and number of formula units in the sample (6,7,5) / Molar Mass conversions worksheet homework (grade/review following day) (5)
Wednesday / Focus Standard:
C.8C: calculate percent composition and empirical and molecular formulas. / Students will calculate percent composition of a compound / What is the percent composition of skittles by color in a skittles bag? (6, 10) / Notes – teacher demonstrates technique for calculating percent composition (3) / Oreos – Determine the percent filling in an oreo, the %C, %H, and %O in the sugar molecule, the grams of C, H, and O in the filling, and the # of atoms of each (6, 7, 5) / Percent Compostion practice worksheet (homework) (grade/review following day) (5)
Thursday / Focus Standard:
C.8C: calculate percent composition and empirical and molecular formulas. / Students will determine empirical and molecular formulas of compounds / Simplifying/reducing fractions and ratios and how it relates to reducing ratios of whole numbers in molecular formulas. / Notes/Group practice – Identfying formulas for compounds as molecular or empirical formulas (2,3)
Demonstrate how to calculate empirical formulas using percent composition of a compound (3) / Independent Practice – Empirical and Molecular formula calculations worksheet
Friday / Focus Standard:
C.8B, C.8C / Assessment / Quiz – Molar Mass, Percent Composition, and Molecular and Empirical Formulas
