Limitations in resources have prevented our department from offering a traditional laboratory for the non-majors introductory chemistry course. Instead, the authors have developed in-class demonstrations which provide students an opportunity to record observations and data, analyze and graph data, and formulate conclusions as a substitute for the traditional laboratory. Developed experiments cover introductory chemistry topics such as physical and chemical properties, strength of intermolecular forces and phase changes, writing balanced chemical equations, properties of ionic and molecular compounds, and water solubility of alcohols. A typical experiment requires that students record observations and data while the instructor performs the demonstration during the lecture. Once all data and observations have been recorded, students are required to analyze and/or graph their data to formulate conclusions. Each student is then required to turn in a completed lab write-up which includes all recorded data and observations, data analysis and conclusions, and answers to post-lab questions.
