Each session has a form designed for student to record all data and observations, answer relevant questions, process readings by necessary calculations, and draw conclusions from obtained results. This method is not only useful for student but also allows for fair and consistent grading and saves teacher's time required for grading numerous returns. In the development of these experiments, safety was a major concern. It was addressed by choice of chemical components, equipment, and placing the most essential warnings. As with all human activities, there are always dangers associated with doing things and only vigilance of instructor may prevent accidents from occurring.
Additional information is included in the teacher's manual.
The laboratory sessions employ basic equipment and chemicals available in most college stockrooms. Students are also encouraged to enter the data gained from the experiments and proceed with calculations and above all to formulate and answer questions. Hopefully the variety of topics covered by the suggested activities in these 30 laboratory sessions will assist the beginning student to both understand the basic principles upon which the field of chemistry operates as well as to appreciate the many ways in which chemistry makes our daily lives easier.
