1. Adaptations

2. Objectives
SPI Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment
SPI Analyze data on levels of variation within a population to make predictions about survival under particular environmental conditions.
I can:
Identify an adaptation as structural, behavioral, or physiological.
Explain how an adaptation helps an organism survive in a particular environment.

3. Types of Adaptation
Anything that helps an organism survive in its environment 
Adaptations are inherited from their parents
It also refers to the ability of living things to adjust to different conditions within their environments. 
Structural adaptation
Behavioral adaptations
Physiological adaptations
I can identify an adaptation as structural, behavioral, or physiological.

4. Structural adaptations
A structural adaptation involves some part of an organism's body.
Teeth
Body coverings
Shells
Quills
Scales  
Camouflage
Mimicry
A structural adaptation involves some part of an animal's body, such as the size or shape of the teeth, the animal's body covering, or the way the animal moves.  
Teeth - since different animals eat different things, they don't all have the same kind of teeth
Body coverings - Hair, scales, spines, and feathers grow from the skin.  All of these parts help animals survive in their environments.  
Movement - animals find food by moving from place to place
I can identify an adaptation as structural, behavioral, or physiological.

5. Example of Adaptation
The shape of an animal’s teeth is related to its diet.
Herbivores, such as deer, have many molars for chewing tough grass and plants.
Carnivores, such as lions, have sharp canines to kill and tear meat.
I can explain how an adaptation helps an organism survive in a particular environment.

6. Camouflage Camouflage allows an animal to blend into its environment.
Makes it hard for enemies to single out individuals  
I can explain how an adaptation helps an organism survive in a particular environment.

7. Mimicry
Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous.

I can explain how an adaptation helps an organism survive in a particular environment.

8. Plant Adaptations Vascular-stems Root systems Thorns Leave type
I can explain how an adaptation helps an organism survive in a particular environment.
Plant Adaptations
Vascular-stems
Root systems
Thorns
Leave type
Broad:absorb more sunlight
Small needle-like: reduce water loss
Waxy: reduce water loss, protect from fire
Poisonous/toxins

9. Behavioral adaptations
Behavior adaptations include activities or behaviors that help an animal survive. 
Innate
Learned
Survival
Seasonal
Behavior adaptations include activities that help an animal survive.  Behavior adaptations can be learned or instinctive. (a behavior an animal is born with).
Social behavior - some animals live by themselves, while other live in groups. 
Behavior for protection -  An animal's behavior sometimes helps to protect the animal.  For instance the opossum plays dead.  A rabbit freezes when it thinks it has been seen. 
I can identify an adaptation as structural, behavioral, or physiological.

10. Innate vs. Learned Innate Learned Inherited through the genes Examples
Flying for bees, birds
Swimming for fish
Walking for humans
Speaking for humans
Learned from experience or from observing other animals
Examples
Type of language spoken for humans
Riding a bicycle
I can explain how an adaptation helps an organism survive in a particular environment.

11. Survival Behavior Parenting Finding food Predator-Prey adaptations
I can explain how an adaptation helps an organism survive in a particular environment.
Finding food
Predator-Prey adaptations
Predator-animals that eat other animals
Prey-animal being eaten
Marking Territory
Way that animals inform other animals that an area is occupied
Defensive Action
Protect resources, themselves, food, mates, offspring
Courtship
Behaviors used to find a mate
Parenting
Depend on parents for survival

12. I can explain how an adaptation helps an organism survive in a particular environment.
Animal Defense
Some animals use these methods of defense to protect themselves:
Camouflage
Snake
Mimicry
Mexican Milk Snake
Bright colors
Skunk and Poison Arrow Frog
“Hair” projections
Hedgehog quills
Deer Antlers

13. Seasonal Behavior Help organisms adapt to the environment Migration
Hibernation
Estivation
Biological Clock
I can explain how an adaptation helps an organism survive in a particular environment.

14. Migration Animals migrate for different reasons.
better climate
better food
safe place to live
safe place to raise young
go back to the place they were born.
Adaptation that involves an animal or group of animals moving from one region to another and then back again. 
Migration-is the behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again. 
Animals migrate for different reasons.  The reasons are as follows.
better climate
better food
safe place to live
safe place to raise young
go back to the place they were born.
I can explain how an adaptation helps an organism survive in a particular environment.

15. I can explain how an adaptation helps an organism survive in a particular environment.
Hibernation
Period of inactivity in which animal’s body temp., heart rate, and breathing rate slow down to conserve energy.
Bats, woodchucks & bears.
Hibernation- is a deep sleep in which an animal's body temperature drops to about the temperature of the environment.  Body activities, such as heartbeat and breathing are slowed causing the animal to need very little food. 
Animals that hibernate are 
bats 
woodchucks
snakes 
bears.
During the hibernation the animals live off of the fat that is stored in their body. 

16. Estivation Period of inactivity in the summer
I can explain how an adaptation helps an organism survive in a particular environment.
Estivation
Period of inactivity in the summer
hot, dry places
Snakes, lizards, frogs, toads

17. Biological Clock Internal control of animal’s natural cycle
I can explain how an adaptation helps an organism survive in a particular environment.

18. Physiological Adaptations
Behaviors controlled by the brain
Reflexes
Blinking
Pain
Swallowing
Tolerance to a certain poison
Logical thinking
I can identify an adaptation as structural, behavioral, or physiological.

19. Mammals warm-blooded All have some type of “hair” Care for young
Some are very specialized, such as white polar bear fur
Care for young
I can explain how an adaptation helps an organism survive in a particular environment.

20. Birds Leg Length Foot Webbing Beak Shape Roseate Spoonbill (top right)
Laughing Gull (top left)
Beak Shape
Long Billed Curlew (bottom)
I can explain how an adaptation helps an organism survive in a particular environment.

21. Reptiles cold- blooded Scales Some undergo hibernation and estivation
Lay eggs on land
Leg structure and position
I can explain how an adaptation helps an organism survive in a particular environment.

22. Amphibians Cold-blooded Lay eggs in water
Partially of fully webbed feet
Have lungs or can absorb oxygen through their skin
I can explain how an adaptation helps an organism survive in a particular environment.

24. Natural Selection and Population Changes Over Time

25. Objectives
SPI Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment
SPI Analyze data on levels of variation within a population to make predictions about survival under particular environmental conditions.
I can:
Explain how genetic variations within a population help an organism survive longer.

26. Natural Selection
The process by which individuals are better adapted to their environment
“Survival of the Fittest”
The fittest survive to pass on their traits to the next generation.
Examples:
Insecticide resistance
Speciation
Galapagos finches “
I can explain how genetic variations within a population help an organism survive longer.

29. Genetic Variation
Differences that exist naturally among the members of a species
Some traits are better suited than others to survive in their environment
