The title of book 6 is "Exploring Earth's History" and its another foray into geology (oh joy!!!)
After a brief introduction in chapter one, chapter two looks at geological time and stratigraphic columns.
Chapter three is a bit of a mixture. It starts off looking at fossils (there are some copies in the home kit for us to look at) and then goes into radioactive half-lives as a method of dating rocks.
Chapter four looks at igneous rocks (a couple of examples are in the home kit), how they form and how various minerals are concentrated in them.
Chapter five looks at sedimentary rocks (again a couple of examples are in the home kit), how the various sediments are laid down and how the rock is subsequently formed.
Predictably, chapter six looks at metamorphic rocks (yes we have a couple in the kit), their formation and deformation. This chapter also sums up the previous three chapters by introducing the rock cycle.
Chapter seven takes a look at the geology of the British Isles and chapter eight looks at human evolution and how it was affected by geological events.
I didn't find this book too heavy going, it was certainly easier than Book 5. I think it helped that I had attended SXR103 before studying it and so had some understanding of the processes involved.
