Invisible Nature

Invisible Nature
Catherine Barr and Anne Wilson
Otter-Barry Books

Here’s a book to amaze and inspire youngsters, one that looks at the invisible natural forces that have an enormously powerful influence on life on our planet. In it Catherine Barr covers such diverse topics as microwaves, ultraviolet and infrared light waves, electromagnetism, ultrasound and smells.

Say the word ‘microwave’ to young children and most will think of the small oven in the kitchen used to heat food quickly. But there are also microwaves in space and scientists have invented machines that make microwaves that are put to many uses: in medicine, in computers and mobile phones, as well as in navigation by airports and ships.

Each topic has two double spreads, the first explaining how animals use these remarkable powers, the second discusses how humans too have learned to exploit them.

Did you know that some animals rely on UV light for their very survival? For instance it makes lichens glow enabling reindeer to find this much needed food in barren Arctic habitats of Canada, while Sockeye Salmon are able to spot the plankton they feed on when it shows against the UV light of shallow waters.

Much more familiar is the importance of UV in the creation of vitamin D, so vital for maintaining strong muscles and bones in humans.

In all there are fourteen alluring and wonderfully coloured spreads by illustrator Anne Wilson displaying the ways in which these unseen mysterious powers impact upon life on earth

– that ‘secret world beyond our senses’ – making this a book to fire curiosity and ignite the imagination of primary children.
