"Social Behavior" Animal Movement and Behavior PPT Courseware 3

introduction

Have you ever carefully observed ants? Like bees and termites, they are insects that live in groups. Different members within the group work together to maintain the life of the group. Other animals that live in groups like ants include monkeys, baboons, deer, etc. They have a range of social behaviors.

1. Characteristics of social behavior

Do students know what are the characteristics of social behavior of animals?

The characteristics of social behavior are: animals with social behavior often form a certain organization within the group, there is a clear division of labor among members, and some groups also form hierarchies.

Let's take ants and baboons as examples to explore the social behavior of animals.

Female ants, male ants, worker ants, and soldier ants, do they have the same job?

Differently, the intelligence of worker ants is to build nests and feed female ants, male ants and soldier ants. Soldier ants are responsible for the defense of the ant nest. Female ants are specialized "egg-laying machines", also called queen ants. Sometimes its abdomen becomes so distended that it cannot move. Worker ants are responsible for removing the eggs laid by the female and caring for them.

Do you know how shepherds graze their animals?

As the "leader", the male baboon is the "victorious general" within the group. It gives priority to food and mates, and gives priority to nesting sites. Other members will make a submissive gesture to it and dare not fight back against its attacks. The "leader" is also responsible for directing the actions of the entire community and working with other male baboons to defend the group.

The shepherd only needs to manage the "leading sheep" well, and the other sheep in the flock will follow the "leading sheep".

Why do animals live in groups?

Some animals are not capable of fighting one-on-one with other animals, so they have to rely on the strength of the group. The wolf is such an animal.

Clusters also have other functions. For example, penguins living in the polar regions often gather in thousands to keep each other warm. For example, monkeys also have to unite to prevent unexpected events.

Living in groups is a long-term adaptation of animals to food, enemies and living conditions.

2. Information exchange in groups

The division of labor and cooperation in the group require the exchange of information at any time. Animal movements, sounds and smells can all play a role in transmitting information. Animals often engage in "communication" behavior with each other.

What is animal “communication” behavior?

The so-called communication refers to: "The phenomenon in which individual animals in a group send a certain message to other individuals, and the individuals who receive the message produce a certain behavioral response."

What is the meaning of animal group life?

Group life is conducive to animals' feeding and defense against enemies, allowing animal groups to better adapt to the living environment and maintain the survival of individuals and races.

Next, we will use ants as an example to explore information exchange between animals. Have you ever observed ants carefully? How do they maintain their group life?

Let’s explore the communication behavior of ants

1. Ask questions: Based on life experience, tell a series of behaviors of ants and list the inquiry questions. (The following are some for students to refer to):

(1) How do ants transmit information to their peers?

2. Make a hypothesis: Make a reasonable explanation for the selected problem.

3. Make a plan, implement the plan, analyze the results, and draw conclusions: read the teaching materials and combine the teacher's inquiry prompts to initially formulate a plan, improve the plan, divide the work among members, and conduct independent exploration. Communicate and study problems anytime you find them. (One week, data review, experiment) Report the results after one week.

4. Expression and communication: Each group communicates the process of inquiry, conducts analysis, discusses and reflects, and writes an inquiry report.

3. Summary of this lesson

1. Characteristics of animal social behavior: a certain organization is formed within the group, there is a clear division of labor among members, and in some groups there is also a hierarchy.

2. Information exchange in groups:

Division of labor and cooperation in a group require the exchange of information at any time. Animal movements, sounds and smells can all play a role in transmitting information.

The significance of animal group life: Group life is conducive to animals' feeding and defense against enemies, allowing animal groups to better adapt to the living environment and maintain the survival of individuals and races.

4. Classroom exercises
