Identify the following terms
• Adaptation: an organism’s structures, skills,
and abilities that enable it to survive in its
environment.
• Arthropod: an invertebrate animal that has
jointed legs, a body made up of distinct parts,
and an external skeleton (or exoskeleton).
Identify the following terms
• Classification system: a method of sorting and
grouping things.
Identify the following terms
• Identification key: a list of questions and possible answers
about the structural features of organisms to help identify an
unknown species.
• Sample identification key:
Adult Segmented Land
Animals
Arthropods
Insects
Does the animal have legs? How many legs does the
arthropod have?
What kind of wings does
the insect have?
a) Yes, Go to Arthropods.
a) 6 legs ... Go to insects
a) No wings ... Go to fleas
b) No, Go to Annelid
Worms.
b) 8 legs ... Go to spiders
b) 2 clear wings ... Go to
flies
c) More than 8 legs ... Go
to Many-legged
arthropods.
c) 4 clear wings ... Go to
bees
Identify the following terms
• Insect: arthropods that have three pairs of
jointed legs, a body made up of three distinct
parts, and an exoskeleton.
Identify the following terms
• Warm blooded: refers to animals that keep
their body temperature at a roughly constant
level. This involves the ability to cool down or
produce more body heat.
Identify the following terms
• Cold-blooded: refers to animals that do not
use their metabolism to maintain body
temperature. They control their body
temperature through external means, such as
by basking in the sun or by hibernating.
Discuss with your partner:
How can we differentiate between
living things and non-living things?
( 5 questions)
How can we differentiate between
living things and non-living things?
1. Can it grow and develop?
2. Can it reproduce to make more of its own
kind?
3. Can it make or get food?
4. Can it use food?
5. Can it sense and react to its surroundings?
Discuss with your partner:
Give 2 examples of a living and a
non living thing. Explain why they
are classified this way.

Adaptation
Polar Bear
Uses ice as a platform to
find food.
They have a layer of fat to
help them stay warm and
remain afloat.
Beluga Whale
They do not have a dorsal
back fin which allows them
to move easily under
floating ice.
They layer of blubber to
insulate them in them in
the cold water.
Discuss with your partner:
Name three structures of
arthropods.

2. A hard outside coating called an exoskeleton
that covers the whole body
3. A body made up of two or more distinct parts
