Description
Teach and review cladograms with this fun digital interactive activity. Print and Go – NO PREP! The online cladogram activity walks through what a cladogram is and how a cladogram works. Students are then invited to use provided data to add the T. rex where it beings on the cladogram!
The interactive provides morphological evidence using a series of fossils of T.rex compared to bones of current animals. Students must determine if the T. rex is more similar to a crocodile or a bird – all to answer the question, What did T. rex taste like? They are usually surprised by the results!

This worksheet follows along with the interactive and helps students record what they learn about the T.Rex. Critical Thinking questions are added at the end of the activity that help deepen understanding.
All of this is squeezed into just ONE PIECE OF PAPER (front and back)! Easy print and go activity.
Includes answer key AND a Google Slides version that students can complete digitally.

What some happy teachers are saying about this activity:
This was a great and engaging way to do cladograms. Students asked pertinent questions while completing this, so I think it helped clear up some misconceptions before they completely formed. Thanks! – Brandy A.Students were engaged! Easy to use. Great review of cladograms. – Kayla M.I love the hook with this one. Very detailed activity, goes over all of the little parts that show how organisms are related. – Kristina S.Great way for my students to see cladograms in action. Plus who doesn’t like dinosaurs. – Katie B.One of my students who is on the Autism spectrum and loves challenges did this lesson in class today. Wow! She was so engaged and asked me so many questions, and we also consulted our Earth’s history and timeline poster to figure out where T-Rex’s lineage is in the line of evolution (so we discovered where the T-Rex should go on the cladogram together). Such fun! – Annette B.
