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.
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.
· 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.
· 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.
· 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.
· 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
· 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.
· 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.
· 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
