Essential Question: 

How do organisms & cells make copies of themselves while maintaining their integrity?

Interdisciplinary / TOK links:

In what ways do conservatism and progress valuable to organisms (real and metaphorical)

Learning Objectives:

2.5.1 - 2.5.6 (see DP Biology Subject)

 

 

Assessment Statements   
Textbooks  
   

 

 

 

DATE DAY OBJECTIVES TEXTBOOK(S) LESSON / PRACTICAL ASSIGNMENT RESOURCES
  1

2.5.1-2.5.6 [all]

Allott SG

[pre-lesson]

a) Students write assessment statements by hand

b) Student answers assessment statements using Allott SG

[in next class teacher will take questions from students but there will be no direct lecture]

 

 

 
  2  2.5 (all)
 

Review mitosis steps

  • student each write 5 features of mitosis & interphase (no cytokinesis)
  • collect class features, mix
  • students make sequence (discard duplicates; add what is missing)
  • students do this by phase (just record steps/ features in text by phase to begin)

Students answer "2.5 Writing to learn" questions on paper by hand

Flash animation of mitosis in fish or onion;

 

  3

Prac 6(?)

 

Students will use microscope to identify stages of mitosis: [interphase], prophase, metaphase, anaphase, telophase [cytokinesis] in onion cells; assessed via checklist.

 

   
  4
 
 

Use HHMI article of protein coat variability in pathogenic mircrobes. 

  • Discuss significance of art piece (before reading or describing article). Valuable discussion of symbolism; connect visual thinking to science thinking.
  • Relate content to membranes; possibly:
    • structure and role of membrane proteins in identifying cells (t-cells, antigen presenting cells, plasma cells, etc)
    • antibody and antigen specificity
    • variability in glycoprotein structure (in article in microbes)
    • variability in genes controlling Ab production (may include "jumping" or transposable genes.

Use

 

Harvard "Inner Life" animation of leukocyte activity;

 

   

 

   

 

 
     
   
   
   
Prac option
   Use Logger Pro photoanalysis to tabulate number of cells in different stages of cell cycle.
