Day 51: Extracting DNA

20141215_144319

Science 9 – Today in science 9 the students extracted DNA from strawberries.  The lab is fairly straight forward and is well known in education.  With not too much prep, the students are actually extracting DNA – every time I think about this, it blows my mind!  Most of the students find this pretty interesting too.

Of course, this lab is one of those black box type investigations. I have thought about following up the quiz with an experimental design lab.  Some type of investigation that determines how to maximize the quantity of DNA extracted.  Perhaps I will go over an experimental design next class, using the Smarter Science framework.

One of my blocks had several boys that really struggle to stay focused.  Some of them are super interested in this topic and what the lab is about, but have absolutely no desire or compulsion to write something down on paper.  It’s a puzzling thing for me to figure out – I feel like I’m doing all of the things that need to be in place for an engaging environment, but several kids just aren’t in the right head space.
