WHICH IS THE LONGEST OF THEM ALL?
INTRODUCTION
Animals come in all different
sizes, shapes and lengths. How long is a seahorse? What about a
killer whale? How many centimeters in length is a chipmunk? Is it longer
than a gecko?
TASK
Use the Internet to find out
the length of 1 animal from each of the following groups: mammal, amphibian
and reptile, bird, fish, and insect.
You must have 1
example measured in millimetres, 1 in centimetres, 1 in decimetres, 1
in metres and 1 in multiple units. Construct a graph to show the data
you collected. Your graph should answer the question, "Which animal is
the longest of them all?" Write two other questions to your graph answers.
PROCESS
 Use the following
websites to find the lengths of different animals.
Seaworld
The
Canadian Museum of Nature
Toronto
Zoo
Hinterland
Who's Who
Remember, you want to record the lengths using different
units of measurement. Record your findings on The
Animal Group Fact Sheet .
 Now that you
have the data you need, you are ready to start making your graph. Ask
yourself, what type of graph would be best? What scale will I use? Show
the length of the animals using the same unit of measurement. This should
help you decide on a scale.
 Using your
graph answer the question, who is the longest of them all?
 Write 2 other
questions that your graph answers.
