Sample laboratory topics in a school physics course

Laboratory work (regardless of subject matter) is divided into the following types:

I Carrying out direct measurements of physical quantities

II Calculation based on the obtained results of direct measurements of the parameter dependent on them (indirect measurements).

III Observation of phenomena and setting up experiments (at a qualitative level) to detect factors influencing the course of these phenomena.

IV Study of the dependence of one physical quantity on another with the presentation of the results in the form of a graph or table.

V Checking the given assumptions (direct measurements of physical quantities and comparison of the given ratios between them).

VI Acquaintance with technical devices and their design.
