Instructional Materials :
- Weather chart
- Wall charts
Previous Knowledge :
The pupils have been taught
AMAZING WORLD OF LIVING THINGS
in their previous lesson
Behavioural Objectives : At the end of the lesson, the pupils should be able to
- say what are living things
- say what living things can do
- say what living things cannot do
Living things are things that have lives in them .
.They are alive that is why they are called living things .
Special things that all living things can do are called characteristics of living things .
Characteristics of living things are what all living things like man , animals, plants or trees can do .
The acronym for the characteristics of living things is MR NIGER D:
Movement: All living things can move from one place to another in search of water, food and shelter. The movement is obvious in animals but not so in plants. But plants move. (a lesson on its own)
Respiration: all living things breathe. Respiration is a chemical process that happens within cells to release energy from food
Nutrition: all living things feed. The way plants feed is different from the way animals feed.
Irritability: living things respond to stimuli. They are sensitive when touched. This means they can detect change in their surrounding environment.
Growth; all living things grow.
Excretion: every living thing get rid of waste from their body.
Reproduction: Living things produce young ones of their kind. Reproduction is the ability of all living things to produce and pass genetic information to their babies. Plants reproduce.
(DEATH): There is a debate on whether Death should be considered as a characteristics of living thing or not. Some school of thought has it that death can not be among the characteristics of living things because death is when living things stop doing the other characteristics mentioned. Which means, they are considered living things when alive, so, when dead, they are no longer living things. Therefore, death should not be a characteristic of living thing
Another school of thought is that death is major part of the life cycle of all living things. The argument is that, once something has been born in the animal kingdom or germinates in the plant kingdom, the only certainty is death. That, every living thing has maximum lifespan which is determined by a number of factors.
Based on the above reasoning this school of thought say that death is a very important characteristics of living things.
characteristics of living things?
Characteristics of living things
Living things can move Living things can breathe Living things can eat Living things can feel Living things can grow
Living things can reproduce Living things can pass out waste Living things can die
Plants and animals are living things
The topic is presented step by step
The class teacher revises the previous topics
He introduces the new topic
The class teacher allows the pupils to give their own examples and he corrects them when the needs arise
- What are living things
- Say four things that living things can do
Class teacher wraps up the lesson , gives a short note and goes round to mark
