Chemistry: Balancing SMA
QUICK VIEW
CW/HW: Completed SMA of RXN #1 (___H2O + ___O2 --> ___H202); RXN #2 (___N2 + ___H2 --> ___NH3); and RXN #3 ( ___C3H8 + ___O2 —> ___CO2 + ___H20). Turn in Slideshow (SOLO) or Animations (PAIRS) via Google Classroom.
DN: How do you balance a chemical reactions?
Reminders: If SMA pairs only completed one animation, they can come in at lunch/tutorial and complete the second animation OR they can complete the second animation slideshow style - make sure to turn in video of the first animation.

LESSON OUTLINE
5min Students complete the Do Now.
5min Balancing Chem. RXN SMA Instructions. Teacher outlines steps and difference between Solo (Google Slide Animations) and Pair (Stop Motion Studio) SMA.
20-25min Balancing Chem. RXN SMA. Students make the parts for the animation and use those parts to show the steps of balancing a chemical reaction. For RXN #1 (___H2O + ___O2 --> ___H202); RXN #2 (___N2 + ___H2 --> ___NH3); and RXN #3 ( ___C3H8 + ___O2 —> ___CO2 + ___H20) the steps below are shown.
1. Draw/Show Atoms in Molecules
2. Count the Atoms (Make it obvious what you are counting.)
3. Add Molecule(s) to one side.
4. Count the Atoms (Make it obvious what you are counting.)
(Repeat step 3 & 4 till everything is balanced.)
5. Fill in the blanks of the formula.

10min Students balance the chemical reaction formulas for Level 1 & 2 until they earn 4 or 5 stars. Continue to Level 3 when done.
5min Collect materials. Clean up. Wrap up.
