Many of the concepts encountered in the general chemistry lecture seem foreign and anti-intuitive to the student. One can engage students and help to bring about understanding by offering captivating and illustrative demonstrations that clearly describe lecture topics and exhibit scientific principles. I will discuss teaching demonstrations that I use in my first semester general chemistry course. These demonstrations actively engage the student while also teaching them concepts such as predicting reaction products based on solubility rules, and understanding VSEPR theory through building marshmallow structures, thus giving the student a visual picture of the chemical phenomena. I will also discuss a quantitative analysis of using puzzles to teach Hess's Law.
