About this book

Have you ever thought about what earth really is? 

This book explains that soil is made up of minerals, organic material, air and water. The organic material is comprised partly of dead plants, and partly of living things, like roots, microbes, insects, and worms. There are 400 billion billion worms in the world! They are super important because they help keep the soil full of nutrients and air. Plus they’re food for lots of animals, some of whom use the soil to create burrows. 

Without soil, there would be no plants as food, or trees for oxygen. So, next time you’re splashing in a muddy puddle, why not stop to look at the amazing soil beneath your feet?  

This charming non-fiction picture book is very informative. It’s laid out in a clear, attractive way, with full-colour illustrations of two children discovering the various important elements of soil. The text is simple, without complicated vocabulary, and provides a fascinating peek into a surprisingly busy underground world. 

This would be ideal to use with a class, as the content level and tone are just right for young children. Perfect for inquisitive young minds.
