1. Group Behavior

2. Bell Work: Describe what’s happening in the video.
List at least 2 reasons why you think the birds would behave like this.
Fly together because they are following each other
So they don’t get lost
They like their friends

3. Today’s Objective
By the end of the class, you will be able to name 6 different types of group behaviors and describe how each one helps an animal or species survive.

4. Part 1: Where’s Waldo?

5. Why is it harder to find Waldo? (Write your response to #1 & 2)

6. How about now? (Write your response to #3)

7. Question of the Day
How does group behavior affect chances of survival for the individual and the entire species? WRITE YOUR PREDICTION ON YOUR PAPER

8. Part 2: Think, Pair, Share:
List some advantages or disadvantages: is it better to be a loner (alone) or to be a part of a group? OR

9. Solitary Animals or Loners
Solitary animals live on
their own.
Hunt by themselves
Only interact with other animals to mate or to compete for food and resources

10. Non-social Groups Animals interact loosely
Each animal is acting for their own benefit
Flocking
Herding
Schooling

11. Social Groups
Animals or organisms that live, travel, and work together are in social groups.

12. Advantages of large social groups
Protection from predators or the environment
Easier to find a mate
Large groups can find food together and share it
Population regulation (restricted breeding)
(Write your response to #1-3)

13. Part 3: CLAIM
Group Behavior enhances the chances of survival for the individual and for the entire species.
What is the purpose of surviving? Every organism’s goal in life is to reproduce and pass on its genes. In order to reproduce an organism must survive.

14. Claim: Being part of a group increases your chance of survival
Evidence:
1. Schooling
A group of fish swimming together
Reasoning
Schooling allows fish to swim longer, travel through colder temperatures, and avoid predators

15. Claim: Being part of a group increases your chance of survival
Evidence:
2. Flocking
A group of birds or animals that move together
Reasoning
Safety in numbers, easier foraging (finding food), protection from predators

16. Claim: Being part of a group increases your chance of survival
Evidence:
3. Herding
Hoofed animals group together to eat and travel
Reasoning
While one animal has its head down to eat, another will have its head up looking for predators.
With more animals looking for predators, it is more likely they will survive an attack.

17. Part 4: Example: Emperor Penguins (Write your response to #1-3)
What behavior are the penguins exhibiting?
What are the advantages of their behavior?
How can this behavior increase their survival as a species?
1. They huddle together to keep warm and avoid the snow. 2. They are working together to stay warm. They continue to move around in pattern so that no one is left out in the cold the entire time . If they only cared about themselves, they would be trying to stay in the middle while everyone else was on the outside.

18. Cooperative HUNTING What behavior are the orcas exhibiting?
Think, Pair, Share
What behavior are the orcas exhibiting?
What are the advantages of their behavior?
How can this behavior increase their survival as a species?

19. Claim: Being part of a group increases your chance of survival
Evidence:
6. Hunting
A group of animals will search for food together
Reasoning
By using strategy, the group can take down a much larger prey
The group can confuse the prey, so it runs into another hunter
The group can protect the kill from scavengers

20. Cooperative Defense Think, Pair, Share
What behavior are the musk oxen exhibiting?
What are the advantages of their behavior?
How can this behavior increase their survival as a species?
Notice, the wolves are also working cooperatively. How is this an advantage for the wolves?

21. Claim: Being part of a group increases your chance of survival
Evidence:
6. Defense
A group of animals will work together to defend the offspring
Reasoning
By using strategy, individual members of the group are less likely to be harmed
Protecting the offspring ensures the survival of the next generation and the species.

22. Cooperative FOOD GATHERING
Think, Pair, Share
What behavior are ants exhibiting?
What are the advantages of their behavior?
How can this behavior increase their survival as a species?

23. Claim: Being part of a group increases your chance of survival
Evidence:
6. Cooperative Food Gathering
A group of animals will work together to obtain food that is shared among the group
Reasoning
More food can be acquired in less time, which results in less energy being used to find food
The chance of finding food or capturing prey increases
