Designed Learning Experiences – Surprising Stoichiometry
ATA College Prep instructors strive to develop dynamic and stimulating content that is relevant to each student. Learning experiences are designed to engage students through information while adding intellectual, creative, emotional, and physical layers. Focusing on the goals of opening students’ minds and equipping them with the tools to succeed academically, lessons address the HOW and WHY of each learning activity in addition to the WHAT. This article is the first in a series titled Designed Learning Experiences and will feature unique activities that take place within the CP classrooms.
In example, the students in Mr. Rutherford’s Chemistry class use “stoichiometry” (quantitative chemistry) to predict the amount of baking soda needed to fully neutralize a certain amount of vinegar.
Mr. Rutherford explains, “The kids did the math and then tried measuring in the amount of baking soda they predicted (Alex added it so quickly that the fizz overflowed)… and found, to their surprise, that they had predicted way, way more baking soda than necessary because they didn’t realize that “vinegar” is really mostly water and contains only a small amount of acetic acid (the active ingredient).”
Using skills of analysis, prediction, experimentation and calculation, students adjusted their math for the observed revelation, tried again, and correctly predicted the amount of baking soda that would complete the process.
“An important piece of teaching the sciences is surprise,” explained Mr. Rutherford. “By the time kids are in secondary school, they already feel like they have a pretty good intuitive sense of how the world works. Experiments and demonstrations in which something surprising happens shake them out of their complacency and allow them to feel a little wonder and mystery, which is the motivation for studying science. It’s also very satisfying for them to resolve the mystery and incorporate new information into an updated worldview, which is a decent summary of the scientific process.”
