Lesson 1: Classification Revision Notes
Lesson Objectives
In this lesson, we'll explore a big idea called classification. By the end, you'll learn:
Grade C: Understand classification (putting things into groups based on how they are alike and different).
Grade B: Know how to classify organisms (living things) by looking at their characteristics (special features or qualities).
Grade A: Explain how scientists sort all living things into big groups known as the five kingdoms.
What is Classification?
Classification is like organising your toys or books into groups so you can find what you want easily. For living things, it helps scientists understand how they relate to each other.
The Five Kingdoms
Scientists use five main groups to classify life on Earth, helping us see how amazingly diverse life is:
Animals: Creatures that move and eat food. They can live in different places like land, water, or air.
Plants: They use sunlight to make their own food (a process called photosynthesis). Trees and flowers are examples.
Bacteria: Tiny organisms that can be helpful (like in yogurt) or can make us sick.
Fungi: They don't make their food but get nutrients from dead things. Mushrooms are fungi.
Protoctists: Small, often single-celled organisms, like amoebas, that are too different to fit into the other groups.
How Do Scientists Classify Organisms?
Scientists look at how living things are made, how they live, and how they interact with their environment. They use this information to decide which of the five kingdoms an organism belongs to.
For Example: To decide if something is a plant or fungi, scientists might look at how it gets food. Plants make their own food, but fungi feed on dead materials.
Why is Classification Important?
Understanding how living things are grouped helps us learn more about them and how they fit into the natural world. It's a key part of studying biology (the science of living things).

Keywords and Definitions
Classification (Grouping things based on similarities and differences): Helps us understand how living things are related.
Organism (Any living thing): Can be as small as bacteria or as big as a whale.
Characteristic (A feature or quality of living things): Like how plants make food or animals move.
Explore Classification Further
Learning about classification shows us how all the different forms of life on Earth are connected. It's a fascinating part of science that helps us see the beauty and complexity of the natural world. Keep asking questions and exploring, and you'll discover so much more about the amazing planet we call home.
