Evolutionary trees and fossils

Science Year 6
This unit is part of Year 6 Science The Game of Survival

Objectives

Have you ever wondered how the humble biscuit has evolved over the past 100 years? Well, this is your chance! Create a biscuit cladogram and use your evolutionary expertise in the exploration of bird flight and animal cladograms.

Science Objectives
i) Recognise that living things have changed over time and that fossils provide information about living things that inhabited the Earth millions of years ago.

Working Scientifically

  1. Identify scientific evidence that has been used to support or refute ideas or arguments.

Lesson Planning

Teaching

  • Examine how the fossil record helps us understand evolutionary relationships.
  • Understand what a cladogram is and how it shows evolutionary relationships.

Activities

  1. Explore online the evolution of flight in birds through the fossil record.
  2. Create a cladogram using modern animals.

Investigation - exploring, analysing secondary sources, pattern seeking
Use the principles of biscuit evolution to animal and plant evolution.
