“Somewhere, something incredible is waiting to be known.”
― Carl Sagan (via Goodreads)
In sixth grade science students are still learning the basics of the scientific process, which in our curriculum involves six steps: problem, hypothesis, materials, procedure, data, conclusion. We really try to hammer home all these parts in sixth grade, so that in seventh and eighth they can begin designing their own experiments with control and experimental sets and carefully measured data.
When we start any lab we alway start with the problem, which is a question that the students hope be able to answer by the end of the lab. Then comes the hypothesis, which is the prediction (educated guess) to the question they’ve asked. We ask them to write down what they think is going to happen and why.
Later on during the conclusion portion students are usually asked to reflect back on their hypothesis and decide if they were right or not. Often times they feel that if they have gotten the hypothesis wrong then they have somehow failed the experiment, but this is totally backward. It is through the observation of the unexpected that scientific knowledge is advanced. If the experiment goes exactly according to plan and the hypothesis is totally correct, then we have learned nothing. It is only by observing what we don’t expect that we learn anything at all.
Of course the sad part is most people only see what they want to see, which is what they expect to see. When you expect the unexpected you may actually learn something new, so search for the unexpected, not only in the science lab, but in all aspects of life. Expect the unexpected.
