Activities
•
Define Autotroph and
Heterotroph
Discuss why scientists need to
use models
Describe the structure of the cell
membrane and explain the
chemical nature of the
membrane. They should also be
able to explain selective
permeability and why cells need
this characteristic (discuss
diffusion too)
Construct a cell model
Explain why mitochondria are
required for Eukaryotes and
what may happens when
mitochondria don’t function
Review from last week: Plant vs. Animal, Prokaryote vs.
Eukaryote, Photosynthesis vs. Respiration – game
• Introduce Autotroph vs. Heterotroph
• Make biobottle observations
• Discuss models – what are they? Why do scientists use
them?
• Learn about the structure of the membrane – diffusion
demo with food coloring. Remind students about
selective permeability
• Make a model of the cell membrane
• Brainstorm making a cell model - project Mitochondrial
diseases, and amount of mitochondria in different tissues
• Mitochondrial diseases and number of mitochondria in
different tissues – analyze graph
• Set up bread mold experiment
Homework: Begin to collect household materials for cell
model
Describe the structure of DNA –
nucleotides, hydrogen bonds,
base-pairing
Identify who discovered the
structure of DNA – Franklin,
Watson and Crick
Extract DNA from strawberries
and observe the rope-like
structure of DNA
•
Warm-up: Notecard: What is the structure of the cell
membrane? How does the cell membrane achieve
selective permeability? Why does it need to be a barrier
for the cell?
• Biobottle observations – record
• Learn about the nucleus and DNA – what is it? Why is it
so important? Who discovered the structure of DNA?
Watson, Crick and Franklin - Prezi
• Fill out KWL chart about DNA
• Extract DNA from Strawberries
• Look at “DNA” under the microscope – why can’t we see
clearly? How do we know so much about it then??
• What happens when DNA is changed? Make a snork
activity – see how DNA are the instructions for living
things
Homework: Bring in materials for Cell model – construct
tomorrow
Construct a paper DNA model
Construct a model of a cell and
identify the parts of that cell
with an appropriate key
