Sep 29, 2014 · This instructional videos focuses on types of chemical reactions and reaction stoichiometry for AP Chemistry. It is part I of three parts. This screencast addresses properties of water, an introduction to solution formation, electrolytes vs. nonelectrolytes, the composition of solutions, molarity and preparing solutions from solids or stock solutions. David was the National Math and Science Initiative's Science Teacher of the Year for Arkansas in 2012. Along with consulting for the College Board, he has consulted for NMS as a presenter to AP Chemistry teachers at summer workshops, to Pre-AP Chemistry teachers at Laying The Foundation workshops, and to AP Chemistry students in NMS's ... Step 4 combines the answer from Step 3 with the volume from the problem into the molarity formula. While giving this information students copy down what I am showing them with my document camera. Guided Practice : I then ask students to use this model example from the mini-lesson to attempt the first problem in the Titration Practice Problems . He has taught all levels of chemistry for 23 years and is a College Board Consultant for AP and Pre-AP Chemistry.
