Selected Topics worked on a chemistry modeling lab. Students drew structural formulas of several important biological molecules then modeled them using marshmallows and toothpicks. We modeled ethanol, water, glucose and pyruvic acid ... just to name a few. We related their importance in biology and human bodies.
In computer programming, most of the students are finished with the Pick the Corn problem and are working on the Grand Prix of Karel. Most students now feel comfortable defining new instructions in their programs. We will check programs on Friday.
Tomorrow in AP Biology, we will finish biochemistry ... proteins and nucleic acids. Also, we should have time for an exciting game of Biochem Poker.
We still have dozens of Eastern Tiger Swallowtails visiting out flower beds. Below is a rare female showing intermediate coloring between the yellow morph and the black morph. The black morph is a mimic of the Pipevine Swallowtail which is poisonous ... Batesian mimicry.
