Appreciation of Quantities . Chemistry is a quantitative science. A keen sense of what's important and what's not important can help the experimentalist in performing experiments and can aid the theoretician to separate those ideas that really matter from those that don't. Developing this feeling for quantities takes time and experience. We don't expect you to start with it, but this laboratory should help you along the path to acquiring it.
Any action requires some level of understanding in order to be carried out successfully.
The most important piece of laboratory apparatus you will ever work with is your head. A desirable trait in a good scientist or engineer is the ability to plan and perform neat, elegant, and precise experiments. Again the most important aspect in planning and performing experiments is knowing what and why. Dexterity is much less important than patience, focus, and intelligence, and it is possible even for persons who feel clumsy to become excellent experimenters. Rumored to be a useful habit in science.
