Electricity is the power behind smartphones and thunderstorms and vacuum cleaners. It lights up our homes and cooks our food, but what IS it and where does it come from? Lift the flaps and try some simple experiments to find out.
Sssh, listen... what can you hear? From musical harmonies to sonic booms, discover the science of sound and how we hear things. Why is most of space completely silent? Why does a recording of your voice sound strange? And what do bats, dolphins and a boat full of scientists have in common? The answers are all in this book, with lots of flaps to lift and simple experiments to do at home.
