Middle School Biology Department：6S+ Stimulus and Response

September 29, 2019

Students in 6S+ level did an experiment about scientific method on September 26th. The experiment was to study the responses of earthworm under different stimuli.

Students were encouraged to design several fair tests. They must be clear about the independent variable, dependent variable and constants in an experiment. For each experiment, students needed to design a control group to make sure they can compare the result with it and reach a valid conclusion. During the experiment, they recorded what they had observed very carefully.

By doing this experiment, students achieved a better understanding on scientific method.
