  Classification & Characteristics of Vertebrates

Vertebrate

                  Students’ Learning Outcomes

  1. Classify vertebrates into fishes, amphibians, reptiles, birds and mammals on the basis of their characteristics.

                             Information for teachers

  1. ·         Vertebrates are divided into five major groups i. e. fishes, amphibians, reptiles, birds and mammals.

Vertebrates

  1. ·         Fish have no legs and they swim and live in water. They have fins for swimming.
  2. ·         Amphibians have legs. Their skin is moist. They can live both in water and on land. They swim in water and hop on land e. g. frog.
  3. ·         Reptiles have legs. Their skin has scales. They crawl on land e. g. snake.
  4. ·         Birds have legs. Their skin has feathers. They live on land and can fly in air e. g. sparrow.
  5. ·         Mammals have legs. They have hair on their skin. They feed their young ones on milk. Most mammals live on land and can run e. g. goat, cow.

                                               Material / Resources

                       Chart or pictures of some animals, textbook

                                               Worm up activity

·         Recall the previous lesson of vertebrates and invertebrates to the students.
·         Ask them to name some of the vertebrates and invertebrates.

                                        Development

    Activity 1

·         Show the pictures of fish, frog, sparrow, lizard and dog to students.

·         Divide the class into five groups and give one picture of animal to each group.
·         Ask the students to observe the picture very closely and point out the major distinguishing features.
·         After five minutes ask each group leader to present the characteristics of the given animals in front of the class.
·         Simultaneously make and fill a table on the board in the light of students’ presentations to summarize the characteristics of various animals.
·         Facilitate the students if they give incorrect information and also explain more characteristics of each group of vertebrates. Use the book for this purpose.

  Activity 2

·         On the basis of above activity introduce the five groups of vertebrates  i. e. fishes, amphibians, reptiles, birds, and mammals. Describe the main features of each group supported with examples.

  Activity 3

Explain the classification by drawing a key on the board (the key has been given at the end of lesson plan).

                                         Sum up / Conclusion

·         Vertebrates are divided into five major groups i. e. fishes, amphibians, reptiles, birds, and mammals.
·         Fish have no legs and they swim and live in water. They have fins for swimming.
·         Amphibians have legs. Their skin is moist. They can live both in water and on land. They swim in water and hop on land e. g. frog.
·         Reptiles have legs. Their skin has scales. They crawl on land e. g. snake.
·         Birds have legs. Their skin has feathers. They live on land and can fly in air e. g. sparrow.
·         Mammals have legs. They have hair on their skin. They feed their young ones on milk. Moist mammals live on land and can run e. g. goat, cow.

                                                   Assessment

   Activity 1

·         Show pictures similar to these to the students and ask them to write their distinguishing features on their notebooks.

 

Snake

 

Rabbit

 

Fish
Pigeon

 

Frog

  Activity 2

Ask the students to identify the groups of the animals and write their characteristics.

·         Involve the students in solving the questions given at the end of chapter / units in textbook.

              Follow up

 

·         Ask the students to find the picture of any vertebrate from newspaper or internet and write its characteristics on the copy and also paste it in their notebooks.
