Labs/Investigations

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.

FORMAL LAB REPORT

All Science is formed necessarily of three things: the series of facts which constitute 
the science; the ideas which they call forth; the words which express them. 
Lavoisier
