Praise for Biodiversity by Laura Perdew

Booklist
Top 10 Books on the Environment & Sustainability for Youth: 2020
“Activities and accessible text bring the importance and complexity of biodiversity to upper-elementary and middle-school students.”

Praise for Extinction by Laura Perdew

National Science Teachers Association Recommends
“This book uses the concept of extinction to teach a little chemistry, a little climatology, paleontology, biology (biodiversity), ecology, and a lot of geology. The science information is historical and current, drawing on three–dimensional learning, incorporating science practices to determine what factors affect extinction in general and specifically. The integration of concepts help bring the science alive and relevant.”

Detailed Book Description

What does the ocean do?

The mighty ocean covers 70 percent of the planet, supports more than 100,000 marine species, regulates climate, feeds billions of people, and plays a key role in the carbon cycle.

In The Ocean: Explore a Watery World with Hands-On Science Activities for Kids, young marine biologists learn the ocean’s history and the key roles it plays on Earth, including its part in the carbon cycle and in regulating weather and climate. Explore the polar oceans, intertidal zones, the shallow ocean, the deep open ocean, and the incredible biodiversity adapted to living there. Find out how people use and rely on the ocean and how humans are making a giant impact on this massive body of water.

A compelling narrative style, fun facts, glossary words defined on the page, and links to primary sources combine to take readers on an investigative journey of the ocean.

Additional materials include a glossary, a list of media for further learning, a selected bibliography, and index. All books are leveled for Guided Reading level and Lexile and align with Common Core State Standards and Next Generation Science Standards.
