What is super nature?

Bobbie Kalman (author)

Publisher: Crabtree Publishing Company ISBN: 9781427194411

This intriguing book looks at the remarkable abilities of plants and animals, which need to be studied to make our environment more sustainable. People have already used birds as models for constructing airplanes, but there are so many other models that have not been replicated. Living things live at the depths of oceans and at the tops of the highest mountains, harness the energy of the sun to make food, make oxygen from carbon dioxide, walk on water, build structures that are air-conditioned, and make materials stronger than steel without ever polluting or damaging the environment. They have done all the things we wish we could do. This book will make young scientists aware of the super powers of nature and may inspire some to find ways to change the future of Earth!

Why do animals become extinct?

Bobbie Kalman (author)

Publisher: Crabtree Publishing Company ISBN: 9781427179586

This fascinating book introduces and explains the designations of endangerment from extinct in the wild to vulnerable. Children are also introduced to fossils as a way of learning about animals that lived long ago.
