Activity Introduction

lion-heroQuick summary: This lesson is designed for a flipped classroom, where students learn new content by watching a video in their own time. This strategy provides the opportunity for students to build their knowledge, attitudes and values by themselves, thereby freeing up class time for hands-on work. Students watch a video about taxonomy and phylogenetic trees and respond to a series of questions.

Learning goals:

  • Students understand the purpose of phylogenetic trees and why we use them.
  • Students understand how to create a phylogenetic tree.
  • Students develop skills in communicating complex scientific subjects.

Content description:

Year 10 Science

  • The theory of evolution by natural selection explains the diversity of living things and is supported by a range of scientific evidence (ACSSU185)
  • Communicate scientific ideas and information for a particular purpose, including constructing evidence-based arguments and using appropriate scientific language, conventions and representations (ACSIS208)
  • Extension: The transmission of heritable characteristics from one generation to the next involves DNA and genes (ACSSU184)

Overarching learning goal: Students take responsibility for their own learning by watching a video on taxonomy and completing a thinking routine. By participating in this activity students will understand the purpose of taxonomy and the use phylogenetic trees in taxonomy. They will develop skills in communicating complex scientific subjects.

The flipped lesson: This lesson provides the opportunity for students to explore/build their current knowledge, attitudes and values about phylogenetic trees. While working independently, students are to view the following video and complete tables on the student worksheet. Teachers will also gain insight from students’ responses which can be used to plan other activities.

This visual thinking tools can be useful in examining how and why student thinking has changed based on learning specific content information. It also helps to develop their reasoning abilities and to recognise cause and effect relationships.

Student Worksheet

tree-heroThought starter: What is the tree of life?

Before watching the video below, answer the following questions:

1. What do you think taxonomy might be?

2. Describe what you already know about phylogenetic trees:

Once complete, read the Phylogenetic tree factsheet and watch the video from the start until 2:25 -

Phylogeny and Phylogenetic Trees (

Once you have watched the video, answer the questions below:

1. Did you find this video useful in describing phylogenetic trees? Why or why not?

2. How were the ideas presented in this video connected to what you already knew?

3. What ideas presented in this video pushed or extended your thinking?

4. In your own words, describe why we would create a phylogenetic tree:

5. How might you display connections between organisms in a phylogenetic tree? Describe in words:

6. How might you represent time in a phylogenetic tree? Describe in words:

7. Describe what you see in this very simple phylogenetic tree:
