"Do carrots really help you see in the dark?" To overcome her fear of the dark, Zoey investigates why it gets dark, and learns how animals and plants have evolved to adapt to darkness. We learn about fear of darkness, what makes darkness, day and night, solar eclipses, mushrooms, owls' adaptations for night-time hunting, bats nocturnal behaviour, echolocation, creatures that live in total darkness, and inventions that help us work in darkness.
