We extracted our DNA before breakfast today. Before brushing our teeth we swished around gatorade in our mouth and spit it into a test tube. After we added a drop of dishwashing soap. Lastly, we added rubbing alcohol to the test tube (about the same amount as the liquid that was already in there). Moments after, we could visibly see our DNA being extracted and pulled up into the rubbing alcohol half of the test tube.
Today was our first sunny day in Sao Luis! We took advantage and spent the day outside. We went to a nearby stream and an environmental reserve to collect organisms, water, plants and rocks for our aquarium.
Our last activity consisted of making our own personalized terrarium. What an eventful day!
