The investigation was designed to test the researchers’ hypotheses. Evaluate some aspects of their experimental design to determine strengths and weaknesses in their approach.
a. Explain why it was important for the researchers to begin their investigation by measuring the temperature at different points on the surface of a turtle egg when it was exposed to an external heat source in only one direction. (2 points)
b. Analyze Figure 2 from the paper. Which data function as a control set? Which data function as an experimental set? Do the error bars add important information that assists in drawing a conclusion from the data? Explain your answers. (3 points)
c. Explain why the researchers ran a series of tests using turtle eggs buried in an outdoor set of nests when they had already run a series of laboratory tests. Did running the outdoor series strengthen or weaken their conclusion? Explain. (3 points)
