Learning Objectives
 Students will develop evidence based explanations with
what happens during mitosis (cells undergo specific,
recognizable changes)
 Big Idea (representation): Mitosis cells change to
become specialized
 Misconceptions:
 Growth
 “Cell Sex”
 Exploding/popping
Engage/Explore
 Engage
 Time lapse videos, Sam’s Puppy formative assessment, Root
tip growth
 Note Misconception: Sam’s Puppy (linked cell growth to
stretching or nutrition)
 Explore
 Onion root tip picture cut out and answered questions in
science notebook (group work), Created CER posters
sequencing cells then did a gallery walk
 Note: No poster changes after they begin, also tell them the
specific number of categories for poster
Explain/Elaborate
 Explain
 Show students Mitosis time lapse video to compare to their
poster sequences, students read an excerpt about pmat
and picked out terms that match visuals from earlier
activities
 Elaborate
 Watch cancer video, students look at drugs used to combat
cancer, explain how the drug works/benefits, Zebra fish
embryo growth
Assessment
 Sam’s Puppy
 Onion root tip CER
 Notebook questions
 Gallery Walk
 Vocabulary matching
 Cancer and cancer drug application (elaborate)
Future Changes/Adaptations
 Reduce the number of onion root tip slides (cut outs)
 Narrow the focus of the cancer elaboration to make it
more effective
 Self evaluation areas of improvement (rubric scoring):
 Elaborate: 1 (not structured or guided)
 Technology: 3
Lesson Study 2012-2013
 Macromolecules
 3.2.B: b. * Relate the structure of organic compounds
(e.g., proteins, nucleic acids, lipids, carbohydrates) to
their role in living systems
 Big Idea (representation): Life is built from chains of
molecules
