Explore worlds within worlds on these four amazing journeys. Using your viewfinder, zoom in from the extremely large to the incredibly tiny in eight or nine giant steps.

Four titles in this series: Space; Human Body; Dinosaurs; Nature

IMAGINE you are out in space looking down on Earth. Through your viewfinder you can see the whole globe. Now – zoom in. What can you see now? Seas, mountains, plains, deserts, forests, lakes... Train your viewfinder on a particularly spectacular part of the Earth's surface, The Great Rift Valley of East Africa, and zoom in some more. You’ll find yourself looking at an ancient volcanic landscape, set amid grassy plains. Keep zooming, and you will begin to see some of the inhabitants of this wild savannah landscape: elephants, giraffes, zebras, lions and many others.
Look for the viewfinder on each illustration. Then turn the page
to see what you’ve zoomed in on next. It's like a grand tour
of the living world, beginning with planet Earth itself, then the habitats into which it is divided, the animal community, the plants on which the animals and insects ultimately depend for their food, the micro-organisms that play such a vital role in nature, and finally the chemical basis of life itself.
