In past and present generations, many or most teachers have used the “traditional” teaching method. This method usually includes lectures, worksheets, and testing, which creates a passive learner. I remember how teachers have taught middle and high school classes, usually via lectures. Even some college professors do the same thing.
This leaves most teachers and students bored out of their mind.
More teachers need to put students in more active role of learning not only the basic information but also how to ask questions and solve problems. Hands on activities help reinforce concepts. On of the best types of laboratory experiments is to have students complete an experiment without knowing what the answers or outcomes are suppose to be. Let students discover for themselves where the plant gets its food. After the experiment, discuss the outcomes and correct any misunderstandings.
