Home/Term 1 Topic 2 Classification of living things
Plants, animals and microorganisms, and their habitats make up the total biodiversity of the earth.
Living organisms are sorted and classified according to their shared characteristics.
Scientists have grouped the organisms into a classification system.
The five main groups (called Kingdoms) of living organisms include Bacteria, Protista, Fungi, Plants and Animals.
Basic differences in processes such as movement, nutrition and reproduction, distinguishes plants from animals.
Kingdoms are further subdivided into Phyla/Divisions, then Classes, then Families, then Orders, then Genera, and the smallest group is Species.
Teacher Input 1
Greet the learners.
Ask them to think about what their rooms looked like when they left for school this morning. Did they make their beds? Did they pack away their pyjamas?
Ask the learners who of them think that they are organised people and why?
e.g. It saves time; helps one to find things easier; some people are obsessive compulsive and need to have their things organised; some people do not like clutter and cannot work in an environment that is not organised.
Tell the learners that if we want our lives to be organised, we need to start with our personal space.
Tell them that you are going to show them a very short video about organising and that you will explain afterwards how this is relevant to today’s lesson.
After watching the video, remind the learners that they have learnt about the biosphere which contains all different kinds of animals, plants and micro-organisms.
They will also remember that each type of living thing has adapted to it’s environment – can they name a few examples?
As humans and animals, we experience different conditions on earth -
For example, our climate in South Africa differs a lot from the climate in Alaska, where it is exceptionally cold with snow and ice covering the land. Penguins and polar bears are able to survive in such conditions.
There are many different kinds of living things on earth.
Today we will explore biodiversity, which refers to all the living organisms and their habitats. This includes all the plants, animals and micro-organisms found on earth.
Just like we need a classification system to sort our clutter, we also need a classification system for living things.
Provide an overview of classification of living organisms by using PRESENTATION 1: Classification of living organisms.
Learner Activity 1
Ask learners if they can still remember the term “Mrs GREN” and what it stands for? (Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition).
Can they remember what we call words that are made up of the first letters of things we would like to remember? (Mnemonics).
Now hand out WORKSHEET A for learners to complete in their groups. Explain what is required to ensure that learners understand the instructions.
Note that there is no MEMORANDUM or mark allocation for this worksheet.
