Example text

Why doesn’t an electric eel shock itself? What is your favorite part of the book? Why? If the child has questions, don’t hesitate to respond with questions of your own, such as What do you think? Why? What is it that you don’t know? If the child can’t remember certain facts, turn to the index. INTRODUCING THE INDEX The index helps readers find information without searching through the whole book. Turn to the index on page 48. Choose an entry such as electricity and ask the child to use the index to find out how electric eels use electricity.

An electric eel can live for 10 to 20 years. 36 An adult electric eel’s eyes can’t see much. The eel uses electricity to find out what is around it. An electric eel’s skin has insulation cells. Its eyes don’t have these cells. When an electric eel is young, it can see. But each time the eel makes a burst of electricity, the shock harms its eyes. An adult electric eel is almost blind. But it can still tell what is around it. The eel is still a powerful hunter. 37 Chapter 5 People live along the rivers and streams where electric eels live.

Thorough and up-to-date, these books make important words and concepts easy to understand. Each title meets the life science curriculum standards for lower middle grades. Read all of the Early Bird Nature Books and enjoy learning about the natural world!
