This is the front cover and table of contents for a science workbook. Here it is, rewritten in a simple way!

A Big Book About Living Things

This is a science book made for middle school kids. A woman named Jean Brainard, who has a very high degree in school called a Ph.D., helped write it.

The book comes from a group called CK-12. CK-12 does not try to make money. They want to help make school books cost less for everyone, all over the world. They let people share and change their books for free online.

You can find this book, and other fun learning tools, on their website.

What Is Inside This Book?

This book teaches many things about life science. Here are some of the big topics you will find inside:

• Studying Life: How scientists think, and how to use tools like microscopes (special tools that make tiny things look bigger) safely.
• Living Things: What makes something alive, and how living things are grouped.
• Cells: The tiny parts that make up all living things, and how they work.
• Genetics: How living things pass on traits, like eye color, to their babies.
• Evolution: How living things change over long periods of time.
• Tiny Living Things: Like bacteria, fungi (mushrooms and mold), and other small organisms.
• Plants: How plants grow, change, and react to the world around them.
• Animals: Including animals without backbones (like worms and insects) and animals with backbones (like fish, birds, and mammals).
• The Human Body: This includes bones, muscles, skin, the heart, lungs, brain, and how our bodies fight off sickness.
• Ecology: How living things connect with each other and their environment (the world around them).
• Environmental Problems: Like air and water pollution, and protecting Earth's resources.

At the very end of the book, there is an answer key. This helps students check their work!
