Reflection: Intrinsic Motivation Getting Ready to Explore DNA: Extraction Lab - Section 5: The Classroom Flow: Generating Questions


This is a really simple lab where students are observing a scientific phenomenon but not necessarily making predictions about potential variables for future testing in the classroom. When I first began working with this specific protocol, I was concerned that wasn't enough.  However, I quickly realized that students truly enjoyed the experience of observing DNA and seeing this simple lab procedure uses grocery items that they can purchase in order to replicate and demonstrate the experience at home with their families.  

By keeping things basic, students get to take on additional leadership roles both in class and at home.  In addition, by saving some of the more technical aspects of DNA for the rest of the week, students are able to focus on what they are seeing and doing in the moment rather than stress out about what final product is due.  I like that students use the time to closely observe and question and that they manipulate lab materials and procedures with care and confidence.
