Pre laboratory assignment chemistry answers

A critical skill you will gain in this module is to be able to correctly use volumetric pipettes and volumetric flasks to create solutions.

For students in lab courses, nothing feels more pointless than just going through the motions of a lab procedure without understanding why it is significant. Emphasize to students that experimental science is the basis for the models they learn about in lecture. Lab, unlike lecture, represents professional science in practice. Lab also represents a playground where curiosity is sparked and scientific theories are put to the test. If students recognize this, they will gain a better understanding of what science truly is and may be more motivated in their lab work. A well designed pre-lab assignment can serve all these functions.
