The Chemistry spent a lot of time on Stoichiometry problems today. We are getting close to being real good at these problems. You know what? There's like 7 billion people on Earth , right? I bet less than 0.0036% of all those people know how to do Stoichiometry problems. That's pretty impressive.
The AP Biology finished the Fly Lab, did a practice problem using the Chi-Square test, learned about the Final Exam and got a quick primer on Gel Electrophoresis. Wow, a lot of stuff!
