Scientific Method – Answering Causal Questions


Students examine a flow chart which considers a question about water evaporation. Multiple hypotheses are proposed to test the effects of air flow, light, and temperature on the rate of water evaporation.  Results and conclusions are then given for the experiment.  

 Analysis questions ask students to identify the dependent and independent variables, and suggest variables that would have needed to be controlled in the experiment.  Finally, students create their own experimental question and flow chart.
