Pre-requisite knowledge/skills:

Learning outcomes: The students will be able to:

Identify the seven characteristics of living things Differentiate between living and non-living

Infer that living things have modifications according to their habits, need and habitat.

Materials / resources required: Chart, fact sheet

Essential Unit Questions:

What are the characteristics of living things What are the criteria of classification of plants and animals?

 

Time Class setting/ Resources

Learning Sequence

10mins Whole class  

Introduction: Have the students to take out their home assignment and ask if any one faced any difficulty. Have the students read out their answers and discuss them.

Show to the students a few samples of living and non-living things and ask them to tell the differences between them.

Solicit the reply that they can be classified as living or non-living, natural or man-made.

Ask them what they understand by living and non-living things by giving examples.

 Whole class discussion/Group activity/half chart paper

Phase 1: Instructional Process

Tell the students that the following activity is a group work. Each group has to write down what they think are the characteristics of living things. Ask how can they differentiate between living and non-living things?Divide the class into groups.

Phase 2:

After the groups have finished their work ask them to read

Kavita Grover Page 2

out their answers and using mind mapping tool given as reference write on the blackboard the seven main characteristics of living things

Ask students: What are the different characteristics of livings thing?Conclude by saying that the main differences are:Movement, Respiration, Sensitivity, Growth, Nutrition, Reproduction, Excretion, and.

Let’s now take up each characteristic and discuss about it.Movement:

Ask the students what they understand by movement.

Why do living things move? How do insects, birds, fishes, etc move? Do plants also move? How do animals move? Why do they move?

Respiration: What is respiration? Do plants also respire/how do plants breathe? How do they breathe? How do animals breathe? (Land, water, worms and

insects)Sensitivity:

What do you understand by sensitivity? When you prick your hand what do you do? When you see some insect near your eye what do

you do? What happens when you feel very cold? What are the different sense organs? Do you think plants are also sensitive?

Growth: Ask: What is growth? Do all living things grow? How do plants grow? Give an example? Do animals show growth?

Reproduction: What is reproduction? Why do living things reproduce? How do plants reproduce? Where are seeds produced? How do animals reproduce?

Kavita Grover Page 3

Excretion: What is excretion? Why do living things excrete? How do animals excrete? What do they excrete? Do plants have any organs for excretion?

Nutrition: What is nutrition? Why do living thing need food? How do animals produce food? How do plants produce food? Why are leaves green? Name the process through which plants make their

own food?

Tell the students that living thing must have all the MRS GREN characteristics to be classified as living.

Fact Sheet

Characteristics of living things

1. MOVEMENT

Most living things move. Living things move in order to survive. Plants move but do not move their position. They are able to move parts of themselves. Plants move their roots towards water and towards the centre of the earth. They move their stems and leaves towards light.Animals move to keep themselves safe and to look for food.Some animals move on land, air and water.

2. RESPIRATION

All living things need oxygen to stay alive. They use oxygen to turn food into energy.To obtain oxygen from the air, animals and plants exchange gases between themselves and their surroundings.Green plants exchange gases with their surroundings through holes in the under-surface of their leaves. These holes are called stomata.Animals have different organs of breathing depending in the habitat they stay..

3. SENSITIVITY:

All living things react to stimuli. This means they are sensitive to changes in their surroundings and react to them.

All animals are sensitive to what is happening around them. Example we shiver when it is cold. We withdraw our hand when we touch a hot thing. Some animals have complicated nervous systems and brains. They have a sense of taste, sight, hearing, touch and smell.

Kavita Grover Page 6

Fishes, which live under water, obtain oxygen using gills

Worms get oxygen through the surface of their skin, and insects use breathing tubes called trachea.

Most land animals have lungs. 

Plants also respond to stimuli, but in a different way to animals. Some plants turn towards the sunlight. Their roots sense and move towards water. The sun flower turns its face towards the sun, during the day and droop when the sun has set.

4. GROWTH

All living things grow. This means they increase their size. They can grow taller. They can grow wider.

5. REPRODUCTIONAll living things reproduce, this means that they make copies of themselves before they die..

Plants which have flowers reproduce from seeds. The new seedlings then grow into plants. Other plants grow from spores and cuttings.

6. EXCRETION

Living things have to remove the harmful effects of waste products from their body.Some of these waste products are: carbon-di oxide, nitrogen and water..

Kavita Grover Page 7

Plants grow taller and wider. Seedlings grow into bigger plants. Plants increase their size in all directions. And their shape is changing all the time.

Baby animals grow into adult animals. Animals also grow taller and wider, but can only increase their size in a definite shape.

Some animals reproduce by laying eggs.Frogs, snakes most fish and insects lay eggs. When the young ones of these animals hatch they have to take care of themselves

Mammals like dogs, cow, rabbits etc give birth to you to young ones. The mother suckles the young ones with her milk. Man is also a mammal.

Animals, such as humans, cats, dogs, remove the harmful effects of the gas carbon dioxide by breathing out. They also breathe out water vapor. The main organs which remove nitrogen waste from the body are the kidneys

Plants also produce waste nitrogen, but only in small amounts. They do not possess organs to remove it, so store it in some of their cells after they have turned it into a harmless substance. Some harmful wastes are excreted from the bark of the tree.

7. NUTRITION

All living things feed. They feed to supply themselves with energy.

Most green plants make their own food. They make their food from the simple raw materials carbon dioxide and water. The green color (chlorophyll) in the leaves together with sunlight allows carbon dioxide and water to be combined. This process is called photosynthesis.

Kavita Grover Page 8

Animals do not make their own food. They feed on plants, other animals, and on dead waste.
