Science is the field of structured knowledge derived from objective observation and experimentation.
To obtain this knowledge, it is essential to have a good command of the laboratory (lab) tools needed to obtain the data to be analyzed. The rigorous use of measuring instruments in the lab allows the experimenter to obtain precise results, which are likely to facilitate understanding and analysis of a scientific phenomenon.
The following concept sheets explain different techniques that must be mastered in the lab.
The techniques introduced in the following concept sheets can be assessed in accordance with the Progression of Learning guide. It is therefore important to fully understand each of the techniques and to practice them in the lab.
Furthermore, the material shown in the following concept sheets may vary from one school to another.
The technique of water displacement can be used to calculate the volume of a solid.
Electrical conductivity can be monitored with the electrical conductivity detector (ECD).
Litmus paper is used to determine the acidity or basicity of a substance.
