EL: Reflecting on Unit 3
Biology and Exploring Unit
4 Biology
Unit 3 reflection – 5 mins
 Individually (and quietly) reflect on the following
questions in relation to unit 3 biology:
 What did I do well? How can I build on that this semester?
 What didn’t I do so well? How can I improve on that this
semester?
 How do I think I went overall in Unit 3 biology?
 What is my learning goal for unit 4 biology? How will I
achieve it?
Unit 4 Biology
“Continuity and Change”
Group activity – 15 mins
 Read pg 26 of study design
(up to Area of Study 1 heading)
 Highlight key words
 Are there words you don’t understand? Discuss what
they might mean and set up a glossary at the front of
your books
 What does your group feel they are most comfortable
with? Concerned with? Interested in learning about?
Aren’t interested in learning about?
 Elect one group member to report back to class
Area of study 1: Heredity
Outcome 1
 On completion of this unit the student should be able to
analyse evidence for the molecular basis of heredity, and
patterns of inheritance.
Area of study 1: Heredity
 Cell reproduction: The cell cycle and DNA replication
 Genes as the units of inheritance; chromosomes
 Gene expression
 Gene regulation
 Manipulating DNA
 Patterns of inheritance
Area of study 1: Heredity
Area of study 2: Change over
Time
Outcome 2
On completion of this unit the student should be able to:
 analyse and evaluate evidence for evolutionary change
and evolutionary relationships,
 describe mechanisms for change including the effect of
human intervention on evolutionary processes.
Area of study 2: Change Over
Time
 Changes in genetic material can result in mutations –
biological novelty is a consequence.
 Changes in allele frequencies – biological evolution is a
consequence
 Changes in biodiversity – new species, extinction, evolutionary
relationships
 Geological change over time; how environmental changes
have consequences for life forms
Area of study 2: Change Over
Time
 Changes in human evolution- how we have changed over time
 Changes in ideas over time; the development of evolutionary
thought
 Cultural evolution – impacts on us and other species
 Changes in technology – impacts on us and other species
 Our impact on other species
Area of study 2: Change Over
Time
Key science skills
Investigate and inquire scientifically:
Formulate questions/hypotheses, experimental design, evaluating
results, presenting, recording and analysing data, drawing conclusions,
acting responsibly and safely
Apply biological understandings:
New contexts, make connections between concepts, solve problems,
analyse issues, evaluate reliability of information
Communicate biological information and understandings
Interpret and communicate information, use scientific terms and
conventions, adapt to audience and purpose
