P.O.T.B.R. 2025 Day 6
Today was a full science day, meaning staying at the campsite for lectures and science work. We finally got the WI-FI set up to do online work but first we had to go through a lecture and review from Jessica and Corbin on the basic things we've been doing so far. Like for our PH strips: a normal PH level is a 7 in terms of testing the toxicity levels of the water samples we've collected. And so far our PH readings have been between 6-5, so only slightly acidic. Or like how our equipment the turbidity tube has a Secchi disc inside and the water is measured by how far you can see the disc at. Things like temperature: the more warmer the water the more bacteria will grow at a faster rate. Which is why we're incubating at 37 degrees Celsius for more than 24 hours, to grow our bacteria. The average temperature we have measured at the bodies of water have been around 15 Celsius so bacteria isn't able to grow as fast. 16 degrees Celsius is the best temperature for the fis...
