Teaching the scientific method? Do it using the subject of osmosis. Students need to analyze the steps in an experiment. They cut out the puzzle pieces, identify words indicative of before, during, and after experiment procedures. Once their sequencing is correct, have students label the hypothesis, procedure, conclusion. They can identify the question and discuss the independent variable.
Next, students can paste the steps of the experiment into their notebooks, or onto a colored piece of paper for posting on the bulletin board.
If you teach osmosis have the class can do this experiment. Do they get the same results? Why?
