Phylogenetic Tree Lesson Plan with Visible Body Suite

Posted on 12/8/23 by Sarah Boudreau

Phylogenetic trees can be a tough concept to wrap your head around—those big, branching diagrams can be difficult for students to parse. 

This is where Visible Body Suite’s phylogenetic tree model comes in! Instructors and students can explore the phylogenetic tree in 3D, and with the help of the Info box, they won’t get lost. 

As former instructor Rob Archibald said, “If Darwin could see this, he’d be freaking out!”

Today on the blog, we’re going to go through a four-step lesson plan using the phylogenetic tree model.

1. Customize as you lecture

Phylogenetic trees can be hard to read, but with VB Suite’s annotation tools, you can make concepts crystal clear as you lecture. 

Begin the lesson by walking students through the basic elements of the phylogenetic tree: branch points and clades. 

Clicking on a part of the tree will bring up its name and a description in the Info box. Use the tag feature, also located in the Info box, to add a tag that identifies the branch point or clade. Using the Draw tool and Notepad, you can annotate in 3D as you lecture, adding circles, arrows, and notes to keep your students focused on the main points.

One important element of a phylogenetic tree is its ability to be read the same way no matter its orientation. By moving the tree in 3D, you can illustrate this point to students, highlighting how the core organizational structure of the tree doesn’t change. 

2. Check knowledge with Flashcards

After students have learned about the organization of a phylogenetic tree, it’s time to review! Flashcards are an excellent tool to use as a short, in-class review because they shake up the monotony of lecture. Plus, Flashcard Decks are shareable, so students can use them to study.

We recommend gamifying the review process further with a Flashcard game show. Using the projector in your classroom, you can show the Deck to the entire class. In pairs or in teams, students can raise their hands to “buzz in” and earn points. Click on the Flashcard to flip it over and reveal the correct answer!

3. Critical thinking 

Now that students have a basic understanding of the parts of a phylogenetic tree, it’s time to explore how they are organized. 

Return to the phylogenetic tree model and examine the clades at the top: the earthworm, frog, pig, and sea star. Ask students to reflect on the order and organization of those four models: What do these animals have in common, and how are they different? Why do you think they’re organized this way on the tree? 

By clicking on the appropriate model in the Related Content box, you can quickly access the animal model so students can walk through the animal’s physical traits and anatomy. 

4. Create a phylogenetic tree

It’s time for students to apply what they’ve learned and build a phylogenetic tree for themselves—though, if we’re getting technical, these are cladograms, not phylogenetic trees.

Ask students to focus on the physical characteristics of the following animals and place them on a tree. This list is from Openstax Biology—you may want to alter it depending on your class’s needs.  

  • Frog
  • Rabbit
  • Lancelet
  • Fish
  • Lamprey
  • Lizard

Students should consider the traits of these animals and determine which traits they have in common. After they have completed their trees, ask students to compare with a partner and discuss why they made those decisions. 

After students have shared their trees with a partner, draw a phylogenetic tree on the board, asking the class to generate the answers. 

Conclusion 

Visible Body Suite’s phylogenetic tree model is an exciting new resource for biology instructors teaching tough concepts to students.  

As instructor Sheila Owen told us, “I think the students will really like it and relate to it better than a line drawing on paper. It makes more sense.”
