Lessons 1-6
2015

2. Discuss the following terms with your partner
Adaptation
Arthropod
Classification system
Identification key
Insect
Warm blooded
Cold blooded

3. 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).

4. Identify the following terms
Classification system: a method of sorting and grouping things.

5. 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

6. Identify the following terms
Insect: arthropods that have three pairs of jointed legs, a body made up of three distinct parts, and an exoskeleton.

7. 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.

8. 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.

9. Discuss with your partner: How can we differentiate between living things and non-living things? ( MRS GREN)

10. How can we differentiate between living things and non-living things?
All living things share 7 easily observable characteristics which include:
M ovement
R espire
S ense
G rowth
R eproduction
E xcretion
N utrition

11. Discuss with your partner: Give 2 examples of a living and a non living thing. Explain why they are classified this way.

12. Give 2 examples of a living and a non living thing
Give 2 examples of a living and a non living thing. Explain why they are classified this way.
Living
Non living
Insects
Rock
Mammals
Air
When I asked myself the questions of MRS GREN (characteristics of life) the answer was yes to all questions.
When I asked myself the MRS GREN questions (characteristics of life) the answer was no to all questions.

13. Discuss with your partner: Explain, with an example, how animals (not pets) adapt to their environments.

14. Explain, with an example, how animals (not pets) adapt to their environments.
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.

15. Discuss with your partner: Name three structures of arthropods.

16. Name three structures of arthropods.
All arthropods have:
Three or more pairs of jointed legs
A hard outside coating called an exoskeleton that covers the whole body
A body made up of two or more distinct parts

17. Discuss with your partner: Name three structures of insects.

18. Name three structures of insects.
All insects have:
Three pairs of jointed legs
An exoskeleton
A body made up of three distinct parts

19. Discuss with your partner: List 5 animals found on land, in air and in water.
