Day 60 – DNA Extraction

WP_20151204_11_13_48_Pro.jpg

Science 9 – Today’s lab was to extract DNA from strawberries.  What a wonderful activity to do.  It’s easily accomplished with minimal expenditures, and while the students would not be able to devise the procedure themselves, the steps are somewhat understandable.  Smash the strawberries to break cell walls and membrane.  Soap further breaks down the cells and releases the DNA from the nucleus.  Ethanol makes the DNA percipitate out of the solution.  Heck, I wouldn’t even come up with the procedure.

There were lots of smiles going around the classroom today and there was a good amount of learning. It was good day at school.
