Chemistry: Balancing Formulas with Paper Molecules
HW: Complete the Chemistry: Naming, Bonding, Weights & More (TWO) worksheet.
CW: Complete Balancing Paper Molecules Poster front & back.
DN: Take one of each handout per pair and cut out pieces.
Reminder: Quiz Tomorrow on Naming Molecules, Drawing Molecules, Balancing Formulas, Finding Atomic Mass/Weight, Finding the number of Neutrons, and Finding the Molecular Mass/Weight.
5min< Students complete the Do Now by taking handouts and cutting out pieces.
5min> Students working in pairs write incomplete formulas on the front and back of 11x17 paper (glue two 11 x 8.5 sheets together at the edge).
10min Class balances the first formula (_CH3OH + _O2 —› _CO2 + _H2O) together using the paper molecules. Glue molecules and correct the formula. (Front of Poster)
10min Pairs balance the second formula (_C2H5OH + _O2 —› _CO2 + _H2O) using the paper molecules. Glue molecules and correct the formula. (Front of Poster)
10min Teacher explains how to complete the homework. Students begin working on the homework.
5min Collect materials. Clean up. Wrap up.
