| Abstract |
|
In place of traditional cookbook laboratory exercises, a nonmajors' chemistry course uses a demonstration-focused laboratory to understand basic chemical theories. Each student spends the lab session preparing, practicing, and learning the chemistry of two unique demonstrations. By selecting demonstrations of different concepts, the students cover the same breadth and type of themes as a traditional laboratory in a new and exciting format. Twice during the semester, students from the course prepare and present two demonstration shows as an outreach program to 3rd–5th graders at local elementary schools. The demonstration format provides the college nonscience students an active-learning experience that is able to provide motivation and generate interest. Overall, the students felt that the demonstration-focused laboratory succeeded in increasing their level of understanding of material, strengthened their interest in science, and held their interest. This pedagogy also provides purpose for studying chemical concepts and direction as students strive to explain concepts to younger children.
