The scientific method is a systematic way to explore the cause of any phenomenon. It involves observation, questioning, hypothesizing, experimenting, collecting data, analysis, drawing conclusions, and sharing those conclusions by communication with peers. Hypothesizing is way to generate a possible explanation, create a model for predicting results, and create a description of how you intend on measuring that prediction. This activity walks students through the scientific method in a way that is fun, creative, and analytical all at the same time. It also examines personal bias, errors in judgment due that result from that bias, and how common bias truly is amongst a sample of researchers.
By the end of this activity, the student should be able to demonstrate an understanding that (a) hypotheses are often predictive statements, (b) hypotheses must be testable, (c) there is bias in thinking about scientific topics even it might be hidden, (d) graphical analysis of data is an easy way to display information, and (e) differences between terms like accuracy and precision. In addition, students will learn to use appropriate terms for analyzing hypothesis (why “correct” or “prove” are poor wording choices).
Included in this activity are teacher notes for helping in the delivery, application, and discussion with students of the activity.
At least 25-30 minutes total in order to give instructions, draw scientists, and answer follow-up questions.
• This can be broken up into two (2) sessions.Either 5-10 minutes instruction at the end of class and homework to draw a scientist. Then the following class period 20-25 minutes of class time to gather the class data set and answer the follow-up questions.
•Or one single session. There must be time given for the students to draw their scientists, gather class data, and then answer follow-up questions (this last part can be done for homework if you run out of time).
ADDITIONAL SUPPLIES NEEDED: Paper, Pencils (colored & regular), Tape, and Students (test subjects)
