The AP Biology students discussed some Chapter 24 stuff like the biological species concept and why it is such a bad, bad idea for an animal like a liger to exist. That is a complete waste of DNA especially as it comes from two species that are endangered.
The Chemistry students took the first exam of the second semester today, the Acid and Base Exam. You know what? I corrected most of them during 6th period of the students will get them back tomorrow! Good for me! Next stop, Nuclear Chemistry!
