THE OAKWOOD MONTESSORI SCHOOL
WEEKLY LESSON PLAN
Christmas Term
Class: Year 6
Week: 6
Subjects: Science
Date: Monday 14 – Friday 18 October 2023.
Topic: Food Chains and Food Web
Objective: By the end of the lesson, pupils should be able to:
a. Relate the food chain to habitat, population and community.
b. Describe producers, consumers and feeding relations.
c. Make food chains in different habitats.
d. Describe how a change in a habitat can have an impact on a food
chain.
e. Describe a food web
Materials Needed: Pictures, video

IGtpZHM%3D), cardboard and markers
Procedure:
1. Welcome the pupils (1 min)
2. State the topic and objectives clearly. (2 mins)
3. Introduce the concept of food chains and ask students what they know.
(2 mins)
4. Write down key terms: producer, consumer, decomposer. (2 mins)
5. Define and explain the concept of a food chain. Use a simple example:
grass → rabbit → hawk. (5 mins)
6. Explain the roles of producers (make their food), consumers (eat other
organisms), and decomposers (break down dead organisms). (5 mins)
7. Use diagrams to illustrate the concept. (3 mins)
Activity 1 (7 mins)
Provide students with a simple food chain diagram.
Ask students to identify the producers, consumers, and decomposers.
Have students work in pairs to match organisms with their roles.
8. Explain how food webs show multiple relationships between
organisms. (3 mins)
9. Use a diagram to illustrate a simple food web. (5 mins)
10. Discuss how food webs demonstrate energy flow and
interconnectedness. (3 mins)
Activity 2 (7 mins)
Provide students with a blank paper and pencils.
Ask students to create their own simple food web diagram.
Encourage students to include at least 5 organisms.
.
11. The teacher summarizes the lesson by explaining the importance of
the food chain and food web. (2 mins)
Age: 10-11 years
CONTROL OF ERROR: Teacher-directed
INDEPENDENT PRACTICES: Classwork
1) What is a food chain?
2) What is a food web?
3) What is the difference between a food chain and a food web?
4. Some beetles break down the remains of dead animals. Some mushrooms
break down the remains of dead trees. These actions most benefit plants by
what?
a. returning nutrients to the soil.
b. releasing oxygen into the air.
c. making space for new animals.
d. decreasing the population of herbivores.
5. Deer and zebras feed on grasses and other plants. Leopards and lions feed
on deer and zebras. Which description is the role of deer and zebra in this
ecosystem?
a. producer
b. carnivore
c. decomposer
d. consumer
6. A herbivore is a consumer that eats
a. plants.
b. animals.
c. both plants and animals.
d. neither plants nor animals
7. The most energy is available at the _____________ level of the energy
pyramid. As you move up the pyramid, each level has less energy available
than the level below.
. consumer
a. producer
b. food chain
c. carnivore
EXTENSION: The pupils draw the food chain of different habitats.

Food Chain and Food Web
Every living plant and animal must have energy to survive. Plants rely on the
soil, water, and the sun for energy. Animals rely on plants as well as other
animals for energy.
Food Chain
A food chain describes how different organisms eat each other, starting with
a plant and ending with an animal.
For example, grass ---> zebra ---> lion
Links of the Chain
Producers - Plants are producers. This is because they produce energy for the
ecosystem.
Consumers - Animals are consumers. This is because they don't produce
energy, they just use it up. Animals that eat plants are called primary
consumers or herbivores. Animals that eat other animals are called
secondary consumers or carnivores. If a carnivore eats another carnivore, it
is called a tertiary consumer. Some animals play both roles, eating both
plants and animals. They are called omnivores.
Decomposers - Decomposers eat decaying matter (like dead plants and
animals). They help put nutrients back into the soil for plants to eat.
Examples of decomposers are worms, bacteria, and fungi.
As you move through the food chain, less energy is available. For this reason,
there are fewer and fewer organisms the further along the food chain you
get.
Food Web
A food web is a group of food chains within an ecosystem. A food web shows
the many different paths plants and animals are connected.
Each level in a food web is called a trophic level.
Level 1: Plants (producers)
Level 2: Animals that eat plants or herbivores (primary consumers)
Level 3: Animals that eat herbivores (secondary consumers, carnivores)
Level 4: Animals that eat carnivores (tertiary consumers, carnivores)
Level 5: Animals at the top of the food chain are called apex predators.
Nothing eats these animals.
