Major Groups of Invertebrates

 Lesson Plan of Major Groups of Invertebrates (Worms & Insects)

                               Science Grade V

                 Students’ Learning Outcomes

                                     Identify key characteristics of worms and insects

                                 Information for Teachers

·         There is a great diversity among invertebrates. Worms and insects are the two major invertebrates groups.
·         The insects are characterized by three body parts (head, thorax and abdomen) and jointed legs. Most of the insects also have wings that help them to fly.
·         Worms have round and elongated soft bodies. The bodies of some worms have segments, like compartments of train.

                                                 Material / Resources

                 Pictures of worms and insects, textbook

                                Worm up Activity

·         Ask them do they know about the “Animals under our feet
·         Discuss Animals under our feet” are worms and insects and they have no backbone.
·         Ask them what types of insects they observe at their homes.


   Activity 1

·         Show some pictures of worms and insects and ask the students to classify them on the basis of their body shapes.
·         Write students’ response on board.

 Activity 2

·         Show the pictures of insects and worms and tell them that these are different groups and have different characteristics.
·         Explain by writing on board the main characteristics of insects and worms: insects (jointed legs, wings); worms (elongated soft body, no legs etc.)

                                       Sum up / Conclusion

·         Worms and insects are the two major invertebrates groups.
·         The insects have three body parts i. e. head, thorax and abdomen. They have jointed legs and most of them also have wings.
·         Worms have round and elongated soft bodies. The bodies of some worms have segments.


 Activity 1

·         Ask the students to complete the following activity.
Sara is a science student and her teacher has asked to collect the worms and insects for collection of animals in laboratory. Help Sara by putting a tick on the animal.
·         On the basis of the results, make groups of invertebrates as worms and insects.

Activity 2

·         Ask the students draw an earthworm and an ant in their notebooks, and write about their structures and their habitats.
·          Draw a table on the board and ask them to copy it on their notebooks and then ask them to fill.
Number of body parts
Number of legs
Present/ Absent

 Activity 3

·         Ask the students to write the names of those insects, they observe in their daily lives.

Activity 4: finger print Ant(fun activity)

·         Ask the students to take an impression of their thumb using any ink or stamp pad and make an ant as shown below
·         Involve the students in solving the questions given at the end of chapter/ unit of textbook.

                                                      Follow up

·         Ask the students to find the picture of any insect from newspaper or net. Ask them to paste the picture on their notebooks and write at least two characteristics.
·         Ask students to collect an insect from nearby and bring it in the classroom and draw its diagram.
Major Groups of Invertebrates
·         Have students create an imaginary creature. Instruct them to draw a picture of the creature and create a fact sheet for their creature. After all students have created their imaginary creatures, let the class classify the creatures. First into vertebrates and invertebrates, next into sub-groups as:
           —Classify Vertebrates into fish, amphibians, reptiles, birds and mammals.
          —Classify invertebrates ito worms and insects
