If you write an experiment report, it will appear in a workbook or a book. If it is not clearly pointed out, you should look at the content and theory of the experiment and then add your own language combination to the theory.

It mainly includes the following contents:

First, the concept of experimental principle: experimental principle is the basis and idea of experimental design.

Second, the experimental principle must first follow the scientific principle of the experiment. The experimental design basis involved in the experiment must be the scientific theory proved by predecessors. For example, the identification of reducing sugar, brick-red precipitation produced by reducing sugar and Fehling reagent, the identification of starch, and the blue color of starch in iodine are all scientific theories.

Thirdly, the expression content of experimental principle and the general idea of experimental design.
