1. Animal Adaptations 6 th Grade Science

2. What is an Animal? A multicelled organism that must eat. A multicelled organism that must eat. Not a plant and therefore its cells do not have cell walls. Not a plant and therefore its cells do not have cell walls. Constantly working to maintain homeostasis Constantly working to maintain homeostasis

3. What issues do animals have to deal with in the wild? Finding food Finding food Finding and keeping shelter Finding and keeping shelter Maintaining internal temperatures Maintaining internal temperatures Safety Safety

4. What helps animals deal? ADAPTATIONS!!! ADAPTATIONS!!! Any genetic trait that helps the animal survive better in its environment Any genetic trait that helps the animal survive better in its environment

5. Adaptations help an animal with Adaptations help an animal with finding/eating food finding/eating food Regulating temperature Regulating temperature Staying safe Staying safe Living in their habitat (water, air, land) Living in their habitat (water, air, land) AKA- maintaining homeostasis AKA- maintaining homeostasis

6. Adaptations can be structural like hollow bones in birds or behavioral like migrating. Adaptations can be structural like hollow bones in birds or behavioral like migrating.

7. Eating food adaptations Example- Example- Carnivores eat meat and have large canine teeth Herbivores eat plants and have flat molars Omnivores eat both and therefore have moderate versions

8. Temperature adaptations ColdHot Thick Fur Thick Fur Blubber Blubber Find warm shelter Find warm shelter Find food/water Find food/water Migrate (leave town) Migrate (leave town) Hibernate (sleep/coma) Hibernate (sleep/coma) Artic fox Thin or no fur Thin or no fur Less fat Less fat Find cool shelter Find cool shelter Find and store water/food Find and store water/food

9. Safety adaptations Prey want to use small amounts of energy and avoid being eaten. Prey want to use small amounts of energy and avoid being eaten. What can they do/have? What can they do/have? Bright colors/poison Bright colors/poison Speed Speed “weapons” ex. Porcupine and skunk “weapons” ex. Porcupine and skunk Blend in to background (camouflage) Blend in to background (camouflage)

10. Camouflage Lab If you are food, it is better to not be seen than have to defend yourself If you are food, it is better to not be seen than have to defend yourself

11. Behavioral adaptations Behavioral adaptations Behavior is an activity or action that helps and organism survive in its environment. It is in response to a stimulus. Behavior is an activity or action that helps and organism survive in its environment. It is in response to a stimulus. An organism’s behavior can be innate (genetic) or learned An organism’s behavior can be innate (genetic) or learned

12. Behavioral adaptations Can be selfish or cooperative Can be selfish or cooperative

13. What have we learned about adaptations? It is all about the environment. The adaptation is only useful in the environment in which it was meant for. Extra insulating fat in Alaska is an adaptation but not if the organism lives in the desert. It is all about the environment. The adaptation is only useful in the environment in which it was meant for. Extra insulating fat in Alaska is an adaptation but not if the organism lives in the desert. Adaptations are genetic. They are passed from parent to offspring. They can not be changed during a lifetime. Adaptations are genetic. They are passed from parent to offspring. They can not be changed during a lifetime.

14. What have we learned about adaptations? Adaptations can be structural and behavioral. For example, Thick fur is a structural adaptation and finding shelter during a storm is a behavioral adaptation. Adaptations can be structural and behavioral. For example, Thick fur is a structural adaptation and finding shelter during a storm is a behavioral adaptation. Adaptations are all about survival. They help an organism survive. Adaptations are all about survival. They help an organism survive.
