Friday Feb 17

Today in class students took a short quiz.  Then, we worked on revising project write-ups.  Common comments to consider are below–the final write up is due March 1.

Tuesday/Wednesday Feb 14

Today in class we reviewed speciation and students looked at examples of common structures in different mammals, and discussed how this is evidence of evolution.  Homework is to complete any unfinished questions about the mammal structures, and to study for the quiz next class.

Today in class students read about speciation and answered questions about the process. Homework: Review slides below and take notes in notebook on page 115 (or next blank page)  Additionally, there will be a short quiz on Thursday/Friday.  See topics below.

Absent Students:  Set up page 114 for Week 6 Do Nows.  Write ‘Absent’ for your Agenda.  Then, describe what cladograms show about living things.  Pick up handouts about speciation in class (no electronic copies available).   These go on pages 112 & 113 for 1st and 2nd periods.

Wednesday & Friday Feb 8/10

Today in class we reviewed mechanisms of evolution and regulation of gene transcription.  Then, students worked through a tutorial on how to use cladograms.  Absent students: For your do now, describe what transcription factors do in a cell.  Be sure to mention RNA Polymerase Fill out this cladogram-worksheet while working through the pages on the link below:

Monday February 6 Instructions

Students:  Title the next blank page in your notebook ‘Lizard Speciation Video‘.   After watching the video, answer the following questions in complete sentences.  (read the questions first, so you know what to listen for!)

  1. Describe the 4 main types of anoles on each island in 1 sentence each.
  2. In what way was DNA sequencing evidence useful in figuring out the relationship between the anoles on different islands.
  3.  Summarize how and why speciation (splitting into different species) takes place in 2 or 3 sentences.

**pause so students can describe the different types of anoles.  Turn on closed captioning**

Today in class students took a quiz on genetic variation & selection.  Then, we watched a video on lactase persistence in humans, and took notes on additional mechanisms of selection.  Homework is to complete the worksheet questions on levels of regulation in gene expression using this website.

Absent students:  Watch this video.  Complete lactase lab questions 15-17.  Review notes posted below.

Thursday Feb 2

Today in class students took a quiz on genetic variation & selection.  Then, we watched a video on lactase persistence in humans, and took notes on additional mechanisms of selection.  Homework is to complete a 4 panel cartoon on page 108 showing one of these mechanisms from the notes.  The cartoon should show evolution of a population that was NOT due to natural selection.  Use at least 4 colors.

Absent students:  Watch this video.  Complete lactase lab questions 15-17.  Review notes posted below.
