Mitosis: Introduction to Mitosis – Part 2

Class began with an example of why mitosis is important: a video showing how salamanders can regenerate lost limbs:

After the video, we worked through a PowerPoint providing students with important vocabulary related to mitosis, with images related to the vocabulary to help reinforce student learning.  Students were encouraged to memorize “PMAT” – an acronym for Prophase, Metaphase, Anaphase, and Telophase which may prove useful on the Biology EOC.  We also discussed the difference between the Washington State Science Standards and the Next Generation Science Standards governing mitosis.  Although Washington State has adopted the NGSS, students are still tested on the WSSS and therefore must navigate between both worlds.  The WSSS (9-11 LS1H) expects students to describe and model the process of mitosis, in which one cell divides, producing two cells, each with copies of both chromosomes from each pair in the original cell.  The NGSS mitosis standard (HS-LS1-4) requires that students use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.  To help students achieve mastery of the content standards, students were introduced to the Mitosis Project.  The final slide of the project includes a list of 12 different projects for students (working alone or in pairs) to chose from.  Students learned a bit about each project and then had time to decide which project they would like to pursue.  We will formally launch the project tomorrow.

We began class with the Meters, Liters, and Grams video:

After the video, we briefly reviewed the Metric System:

We worked through a few practice problems from Appendix A in the textbook (page A-0) which integrate the metric system and dimensional analysis.  After the

We then transitioned to Lesson 60, providing students the opportunity to make connections between Charles’s Law, Boyle’s Law, and Gay-Lussac’s Law.  Although we did not review it in class, the Lesson 60 PowerPoint is available for students to review.  The Lesson 60 Worksheet called for students to use a University of Colorado PhET simulation.  Because our Chromebooks are unable to run Java, students instead observed a teacher-led demonstration of the simulation software.  For homework, students were assigned textbook problems 3-9 (odds).  Students with access to a Windows-based computer are encouraged to try the simulation (embedded below):
