Duration
70 minutes
Prior knowledge of learners
Students have started work on classification of names and groups
Lesson objective/s
By the end of this lesson, students should be able to:
 Define the key features of a Dichotomous Key
 Understand how classification can be used with Dichotomous Keys
 Understand how to create a basic Dichotomous Key
Link to Curriculum (identify relevant Strands and Content Descriptors)
Classification helps organise the diverse group of organisms (ACSSU111 - Scootle ) Science People use
science understanding and skills in their occupations and these have influenced the development of practices in
areas of human activity (ACSHE121 - Scootle )
Identify questions and problems that can be investigated scientifically and make predictions based on scientific
knowledge (ACSIS124 - Scootle )
Construct and use a range of representations, including graphs, keys and models to represent
and analyse patterns or relationships in data using digital technologies as appropriate (ACSIS129 Scootle )
Evidence of learning
Students can describe the key features of a dichotomous key
Create a basic dichotomous key
Classroom Management Strategies
Implore school rules on phones
Maintain engagement by trying to engage entire class in group activity
Resources
Whiteboard
Video on dichotomous keys
Differentiation strategies
Gradual release model
Use f class activity to give students better understanding on a dichotomous key by creating one
Lesson Introduction
Introduce students to lesson
 Introducing the topic Quickly go around and ask about their holidays (build rapport)
 Engagement of the
learners
Lesson Body
Use gradual release model through lesson
1stly explain what a dichotomous key is the two types and what occupations might use it
 Delivering the
taxonomists, researchers etc
content through
Next play this video on them

Lesson Conclusion
 Concluding activities
 Summarizing the
lesson
Evaluation / Reflection
now students will need to write three things they may use to separate a group of 8
animals that they get to name
next as a class students will create a key to identify them as students! Starting with male
and female
Students are to recap they key features of the dichotomous key and why it might be
used to identify groups using classifications
