New Visions Biology Investigation: The Role of Light in Melatonin Production

This activity describes a scientific study on the effects of E-Readers (iPads) on melatonin production and sleep. Students must identify variables, write a research question, analyze the data for relevant patterns, and evaluate the strengths and weaknesses of study. This student-centered activity aligns with the New Visions Biology curriculum in Unit 3 (Evolution of Sick Humans). Melatonin is another example of a genetic mismatch in humans that clashes with our modern environment. Many stu
