Labs/ Experiments

The chemistry laboratory is a place to explore and experiment. The goal is not to know that a scientific theory exists or a mathematical theorem provides an answer, but why and how. It is one of many stages that offer a collaborative, team-based setting in producing knowledge and connecting atomic interactions to the natural phenomena that we experience and see on a daily basis. The laboratory is beyond simply learning content, but the environment where students engage in learning from mistakes and problem solving.

Purpose of lab work:

In order to get the most out of lab work, it is important to keep in mind the main purposes of lab work is:

1. Develop an understanding of the complexity and ambiguity of empirical work;

2. Gain skills to calibrate and troubleshoot equipment and instruments used;

3. Learn to work with others (i.e., carry out complex tasks, share the work of the task, assume different roles, and contribute and respond to ideas);

4. Develop safe and conscientious lab habits, techniques and procedures.
