The Echo the Bat Book
The Adventure's of Echo the Bat introduces remote sensing to our youngest future scientists. The book tells the story of Echo to children ages 5 - 9. Landsat images of the five habitats Echo travels provides a backdrop for the adventure. The text emphasizes shape, pattern, and texture of the satellite imagery and engages children to lift-the-flaps within the images. When the flaps are lifted, pictures of the land features viewed from ground level are displayed. This is a great resource for parents and teachers alike.

ORDER A COPY
The Echo the Bat book is available from NASA's Central Operations of Resources for Educators (CORE) or the Government Printing Office .

LESSON ACTIVITIES
To engage children beyond the book, check out our lesson activities that reinforce four basic themes or concepts fundamental to the interpretation of satellite imagery (perspective, shape & pattern, color, and texture).

ABOUT THE BOOK
As Echo begins his journey in search of the Bat Cave, he doesn't know that there is a satellite flying high in the sky above him. The big pictures in the second half of the story show you what the satellite sees. Lift the pop-up pictures to see what Echo is seeing as he is flying. As you read the story, ask the child what shapes they see. Can they recognize a pattern? Can they describe a color or a texture? After reading the story, go back through the pages with the satellite pictures and ask some of the following:

Perspective
Do you think that the satellite and Echo are looking at the same city, river, mountain, collection of fields, and desert? They are. Are you surprised? What does the city look like from the satellite's view? What does it look like to Echo as he flies over the streets, yards, and buildings? What do you see when you ride or walk through a city? How can the same buildings, streets, and yards look so differently when seen by a satellite, by Echo, and by you?

Shape/Pattern/Color
Close the pop-up pictures so that you can see only what the satellite is seeing. Pretend that you are riding on the satellite and looking down. From your perch high in the sky, what colors do you see? What shapes and patterns do you see? What kinds of shapes and patterns have the same colors? Pretend that your friend is flying beside Echo and can talk to you through a special telephone. What colors, shapes, and patterns do you see from your satellite view? Can you guess what your friend is seeing as he/she is flying with Echo? Lift the pop-up pictures one at a time to test your guess. How many guesses did you get right?

Texture
Look at each one of the satellite pictures with pop-up pictures hidden. Do any parts of the satellite picture look like they could feel rough, smooth, bumpy, hard, spongy, feathery, soft, sticky, sharp etc. Choose a pop-up picture section and try to describe the texture (what it would feel like if you could touch them). Guess what you will see when you lift the pop-up. Were you right? What kinds of textures do mountains, rivers, fields, cities, canyons have? Can the texture in a satellite picture help you identify a feature on the ground?

What to expect?
At the end of this book, children ages 5-6 should be able to distinguish between what a satellite sees and what Echo sees. Older children (ages 7-9) should begin to describe what the satellite is seeing by just looking at the satellite view. Younger children should be able to identify patterns and color in the satellite image and compare these to what Echo sees. Older children should be able to describe the location of the these patterns and colors such as the square pattern of irrigated crops are near the river and green forests are on the tops of mountains. Texture is another important tool scientists use to interpret satellite imagery. Younger children should begin to extend the concept that texture is not only the way something feels, but is also the way something looks. Older children should be able to make more elaborate observations about texture in the satellite images.

BIG BROWN BATS Big brown bats live almost everywhere in America, even in mountains and deserts. In Summer, many rear their young in the walls and attics of buildings, so people often see them flying through yards or around street lights in the evening. During winter, many travel to the nearest cave or mine to hibernate till spring. Others hibernate in buildings or deep rock crevices. Amazingly, during hibernation, they can allow their body temperatures to fall below freezing and still survive. Big brown bats are a farmerÕs best friend. Even a small colony can eat many hundreds of thousands of crop and garden pests each summer. If youÕd like to attract some to your yard at home, you might want to build a bat house.
