Topic Overview
Quick Facts
Animals on land have padded feet in order to
sneak up on their prey.
There are four types of tracks left by a snake,
each representing a different method of travel – rectinilear, concertina,
serpentine, and sidewinding.
The single greatest threat to green sea turtles
is the development of Fibropapilloma Tumors, a disease caused by unknown
reasons has reached epidemic proportions in geographic locations as distant as Hawaii,
Florida and Australia.
Night vision goggles and glow-in-the-dark
tracking powder can be used to track animals at night.
Black bears use the same trails over and over
for generations. They tend to place their paws in exactly the same spot every
time they follow the trail.
Male and female deer leave different tracks.
Males have wider shoulders, so that the hind tracks (the ones on top) will tend
to fall inside the line of travel. Female deer have wider hips, so that the
hind tracks will fall outside the line of travel.
There are four satellites used to track animals.
These satellites are part of the Argos
data collection system sponsored in part by the National Oceanic and
Atmospheric Administration (NOAA).
Animal scat dries from the inside out.
Salvador Dali owned a pet ocelot. He once traveled
with this pet aboard the luxury cruise liner SS France.
Begin the Lesson
Animal tracking is the process of finding animals in the wild.
It is important to observe animals in their natural habitat in order to measure
biodiversity, estimate population size, monitor ecological interactions, and
study behavior. The large variety of techniques for tracking animals includes:
1) the collection of visual and acoustic observations; 2) the analysis of
footprints and other physical tracks through mud, sand, snow, and vegetation;
3) the analysis of animal scat, hair, and fur; 4) the use of live traps and
camera traps; and 5) the use of radiotelemetry and
satellite tracking.
Whole Class Introduction to the
Lesson
You will need at least one
computer with Internet connectivity and a projection device, a classroom with
more than one computer, or access to a computer lab.� This introduction will take approximately 10
minutes to complete.
Go to the page
http://nwwoodsman.com/TrackingGame/TrackinGame.html Read the introductory slide to the class and then click on
“Start Tracking Game.” As a class, try to guess the five mystery animals using
the tracking clues provided in the pictures and audio.
Sample Questions:
What do you see in the picture.
How did the animal leave this mark?
How might we tell what time the animal passed by
this location?
Where do you think this animal lives?
What do you think the weather is like where this
animal is?
What does the sound tell us about the animal?
What type of animal do you believe made these
tracks?
As part of the introduction, you
may want to review some of the glossary terms in advance of students going
online. At this point you can launch the WebLesson as whole-class activity
using a projection device, or you can assign students to work individually or
in teams in a computer lab.

Introduction What do you see when you visit the zoo? Maybe you can watch polar bears or gaze on a giant anaconda. Zoos bring animals out of the wild and into our own towns.
Zoos are also important in helping to protect threatened animals. Humans build more cities and roads and this destroys the natural habitats. Animal scientists are called biologists. They work hard to learn about the needs of different animals. They find and track animal populations in the wild. They tag and follow the animals. They look at animal tracks, fur, and droppings. This helps us to understand how animals behave and what they eat. Tracking animals is also a fun activity. You too can track animals to discover what types of animals roam through our backyards and parks. We can even use tracking techniques to keep track of members of our own species. Scenario You have made friends with a brown bear from the zoo. You go on a field trip to the forest. Together, you will follow the track that bears take and learn about the way they live and how they survive.

Conclusion & Project
Conclusion We can learn more about animals by watching them. Both art and science are a part of animal tracking. We can search for paw prints in the snow, we can look at damaged plants, and we can pick through the remains left behind by animals to help us guess the how an animal acted and where they went. Cameras are often used to observe animals without them knowing we are there. These are called critter cams. We can take pictures and video to help us learn more about how animals live and move.
Project You have spent a fun day in the forest with your friend the bear from the zoo. Describe all of the ways the bear moved in the forest. Also, describe the bear’s activities. How did you use tracking to help you learn about the bear?
