INTRODUCTION

Wow! You have just graduated from Fish College and the Arizona Game and Fish Department would like your help.

Since fish live underwater, studying them can be difficult. Scientists have solved this problem with computers. First, they need to catch a fish. Then, they put a very small computer inside the fish that allows them to find it later. When they release the fish back into the water, the computer works like a radio, sending out a noise that can be heard with special tools. Every few weeks, the scientists use a boat to find the fish in the lake. Now they are asking for your your help.

Are you up to the challenge? If so, move on to the Task for more information.
