Laboratory investigation procedure and corresponding steps of the scientific method (modified from Sterner, 1998).

Detailed ProcedureSteps of the Scientific Method
Step 1 Pre-laboratory presentation: overview on ectothermic and endothermic animals. Outline the laboratory activity. Divide class into groups of four to six students and hand out datasheet. Observe 
Step 2 Ask groups to work together to answer questions 1 and 2 on datasheet. Ask questions 
Step 3 Ask groups to generate hypotheses. Instructor checks that these are valid, properly formatted scientific hypotheses. Generate hypotheses 
Step 4 Groups individually go to one of the three stations (mouse at room temperature, lizard under heat lamp, lizard at room temperature). At each station, groups take a thermal image using the FLIR ONE camera. Upon completion at one station, each group goes to another station until all three stations have been visited by each group. Test hypotheses, collect data 
Step 5 Groups provide their temperature data to the instructor. Class data are pooled and made visible to all students. Results are analyzed by taking averages across groups. Analyze results 
Step 6 Once students have class data, groups work together to answer question 5 on datasheet. Draw conclusions, interpret results 
Step 7 Instructor reviews responses to question 5 on datasheet with whole class to allow for discussion of similarities and discrepancies across groups. Evaluate the hypotheses, revise unsupported hypotheses as needed
