Weak Acid + Weak Base = Lesson Learned
Fourth-graders present the sixth annual Washington State Travel Exhibition, the culmination of a yearlong inquiry into a town or city in the state of Washington. The research was published in student created brochures, posters, artifact displays, and websites.
Upper Schoolers in Dan Jewett's Chemistry class revisit a lab from last week to investigate why the results were so varied. The culprit: the use of a weak acid and a weak base while trying to measure levels of carbon dioxide. Learning from the failure, Dan and the students adjust the assignment appropriately.
