In this lesson, students will be coming to grips with the geological timescale of the Earth, of life on Earth, and of human history.
They will be exploring the colourful history that explains how scientists can detect the colours of creatures long dead, and identify hints of early microbial life interacting with the atmosphere and lithosphere.
