Light is more than just light bulbs and sunshine. Researchers can use different types of light to investigate and do a range of things. This activity is based on the work being carried out at The University of Oxford where researchers are using x-ray tomography (CT scanning) to visualise and measure the 3D structures of fossilised organisms that are still encased in rock.
Students will classify-modern day vertebrates before repeating with extinct animals. They will then go on to use evolutionary trees and see how palaeontologists are using x-rays to study fossils in order to collect evidence about how living things evolved.
Learning outcomes: 1) Classify vertebrates based on their similarities and differences; 2. Use evolutionary trees to explain why species have similarities and differences; 3) Describe how x-rays help gather evidence for evolutionary relationships.
