Lesson Lesson Innovation Of Nutrient Chain Full General Scientific Discipline Shape Iv

Lesson Plan of Food Chain

General Science Grade IV

Students’ Learning Outcomes

·         Define producers, consumers as well as decomposers as well as explicate their importance inward nutrient chain.

·         Make a unproblematic nutrient chain to demonstrate human relationship with producers, consumers as well as decomposers.

Information for Teachers

·         Plants are called producers because they are able to hit nutrient (glucose) from carbon dioxide as well as H2O inward the presence of Sun light.

·         Animals can’t brand their ain nutrient as well as hence they must eat plants or other animals. That’s why they called consumers.

·         Consumers tin live divided into 3 groups;

v  Animals that eat entirely plants are called herbivores or consumer-I e.g. rabbit, sheep, goat, moo-cow etc.

v  Animals that eat other animals (herbivores) are called carnivores or consumer-II e.g. lion, leopard etc.

v  Animals that eat other animals (carnivores) are called consumers-III e.g. snake, hawk etc.

·         Animals feed on dead trunk of plants as well as animals as well as afterward decomposition convert them into simpler compound, are called decomposers e.g. bacteria as well as fungi.

·         A nutrient chain is the sequence of “who eats whom” inward an environs e.g.

·         Arrows represents the unloosen energy time period inward a nutrient chain.

·         If i part of a nutrient chain alerts, the whole nutrient chain is affected. For example, if a illness all of a abrupt wiped out butterfly caterpillars, it would touching owls, eagles as well as many other animals.

Grass----------butterfly Caterpillar ----------Owl------------Eagle

Material / Resources

Pictures of animals as well as plants, charts of nutrient chain, papers, textbook

Worm upwards Activity

·         Ask questions relevant to the topic:

v  From where practise nosotros acquire our food?

v  Why practise nosotros ask food?

v  What practise plants as well as animals acquire their food?

v  From where practise animals acquire their food?

v  From where practise plants acquire their food?

v  How we, animals as well as plants are related to each other?

·         To brand nutrient chain, describe relation with plants, animals as well as human e.g.

     Plants --------------- Cow -----------------Man

Development

Activity 1

·         Demonstrate roughly examples of unproblematic nutrient chains.

·         Introduce the concept of plants every bit producers i.e. organisms that brand their ain nutrient through photosynthesis.

·         Introduce the concept of animals every bit consumers i.e. organisms that eat producers or other consumers.

·         Explain the operate of decomposers inward all nutrient chains.

·         Ask students to brand a nutrient chain by making a sequence of the next organisms. The students volition likewise advert the producer as well as the consumers.

Activity 2

·         Introduce a complex nutrient chain i.e. with to a greater extent than than i consumer. Categorize the consumers every bit consumer- I, II, III as well as and hence on.

Activity 3

·         Reinforce the learning of nutrient chain through the next role-play:

v  Write the discussion producer, herbivore, carnivore-I, carnivore-II as well as carnivore-III on a separate paper.

v  Give i newspaper to each student.

v  Whatever the newspaper says, that becomes the student’s operate inward the nutrient chain.

v  Paste the newspaper to their backs.

v  Herbivore tries to grab the producer. When a producer gets tagged the ii students link arms.

v  Carnivore-I tries to grab the plant eater as well as when he / she is successful, they link arms.

v  Carnivore-II tries to grab the carnivore –I as well as when he / she is successful, they link arms.

v  Similarly, carnivore-III tries to grab the carnivore-II as well as when he is successful, they link arms.

·         Ask students to describe the developed nutrient chain on paper.

Sum upwards / Conclusion

·         Each living thing, whether it is a found or animal, depends on nutrients as well as unloosen energy to survive.

·         Food chain tells us how the nutrient is passed from organism to organism.

·         All nutrient chains start with plants that brand their ain food. These are called producers.

·         Next come upwards organisms that eat plants. These organisms are called consumer-I as well as nosotros know that they are herbivores.

·         Then come upwards the animals that eat herbivores. These are called consumer-II as well as nosotros know that they are carnivores.

·         In all nutrient chains; when whatever organism dies, it is eaten as well as broken downward yesteryear decomposers. Some bacteria as well as fungi are decomposers.

Assessment

Activity 1

·         Ask students to brand corrections inward the next nutrient chain

Activity 2

·         Make a tabular array on the board as well as inquire students to re-create the tabular array on their depository fiscal establishment complaint books.

Consumer-II	Organism that feeds on plants
Consumer-I	Order inward which nutrient passes from i living affair to another
Producer	Break downward the dead trunk of animals as well as plants
Food chain	Living organism that is capable of manufacturing its food
Decomposer	Organism that eats animals

Activity 3

·         Ask students to brand a right sequence of plants as well as animals inward the next activities (or the similar ones). If pictures are non available, write the names of these organisms on the board.

Follow up

·         Ask students to consummate the nutrient chains yesteryear filling inward the blank boxes with the right consumers or producers given inward the underneath nutrient chains.

Food chain 1:

Grasshopper, Grass, Hawk, Snake, Rat

Food chain 2:

Birds, Cat, Snail, Grass algae

Food chain 3:

Grass, Fox, Rabbit, Bear

Types of organisms	Food chain 1	Food chain 2	Food chain 3
Producer
Consumer –I
Consumer-II
Consumer-III

·      

   Ask the students to separate unlike nutrient chains inward the next diagram.
