Exploring Food Chains and Food Webs

Slide 1 - Slide

This item has no instructions

Learning Objective
At the end of the lesson you will be able to define and differentiate between food chains and food webs, identify the different types of organisms in a food chain/web and understand the importance of each organism in the ecosystem.

Slide 2 - Slide

Introduce students to the aim of the lesson and what they will be learning.
What do you already know about the relationships between organisms in an ecosystem?

Slide 3 - Mind map

What are Food Chains?
Food chains show a sequence of organisms in an ecosystem where each organism is the food of the next organism in the chain. For example, grass is eaten by a grasshopper, which is eaten by a bird, which is eaten by a predator.

Slide 4 - Slide

Explain the concept of food chains and provide examples.
Types of Organisms in a Food Chain
Producers, consumers, and decomposers are the three types of organisms in a food chain. Producers make their own food, consumers eat other organisms, and decomposers break down organic matter into nutrients that can be used by plants.

Slide 5 - Slide

Introduce the types of organisms and their roles in a food chain.
What is a Food Web?
A food web is a more complex representation of the interactions between organisms in an ecosystem. It shows how different food chains are interconnected and overlapping.

Slide 6 - Slide

Explain the concept of a food web and how it differs from a food chain.
Importance of Organisms in a Food Web
Every organism in a food web plays an important role. Removing one organism can have a ripple effect throughout the entire ecosystem.

Slide 7 - Slide

Discuss the importance of each organism in a food web and how removing one organism can impact the entire ecosystem.
Food Chain Examples
Provide examples of food chains in different ecosystems, such as a forest, a pond, or the ocean.

Slide 8 - Slide

Show examples of food chains in different ecosystems and how they are interconnected.
Food Web Examples
Provide examples of food webs in different ecosystems, such as a desert, a coral reef, or a grassland.

Slide 9 - Slide

Show examples of food webs in different ecosystems and how they are interconnected.
Group Task
Divide into groups and create a food web for a chosen ecosystem. Include at least five different organisms and explain their roles in the ecosystem.

Slide 10 - Slide

Assign students to groups and provide instructions for the group task.
Food Chain vs Food Web
Discuss the differences between food chains and food webs and why food webs are a more accurate representation of the relationships between organisms in an ecosystem.

Slide 11 - Slide

Summarize the differences between food chains and food webs and why food webs are more accurate.
Conclusion
Recap the main points of the lesson and how food chains and food webs are important in understanding the relationships between organisms in an ecosystem.

Slide 12 - Slide

Conclude the lesson and summarize the main points.
Write down 3 things you learned in this lesson.

Slide 13 - Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 14 - Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

Slide 15 - Open question

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
