The First Few Weeks of the 2nd Semester!

• Tues 1/28:  Hand back Semester Final Exams, check them over, and recollect.  Introduction to what we will cover this semester.  Notes on meiosis, how it is different from mitosis, and the 8 phases.  Do first side of meiosis worksheet, identifying the phases.  Read 3.3.
• Thurs 1/30:  Notes on the Higher Level meiosis.  Synapsis and crossing over.  Do the "creature" activity on the back side of the meiosis worksheet.  Using 2 cards, determine the genotypes and phenotypes of your creature family and then draw a family portrait with your table group.  Read 10.1 (higher level meiosis).
• Mon 2/3:  Notes on genes, mutations, gene mapping, the Human Genome Project, etc.  Finish the Family Portrait if necessary.  Read 3.1.

Welcome Back to IB Biology in 2020!!

It's 2020 and we're almost done with the First Semester of IB Biology!  Are you excited!!?  We are going to cover a short unit on Cell Division, Finish Photosynthesis by doing a Chromatography Lab, and review for the Semester Exam.  Remember that you can still put together a Book Group, but you have to do it quickly because your meeting and book review must be done by Friday 1/17/20!
