LEARNING OBJECTIVES
By the end of the lesson, pupils should be able to:
1. Explain the meaning of changes in nature.
2. Define temporary and permanent changes.
3. Identify examples of temporary changes.
4. Identify examples of permanent changes.
5. State the differences between temporary and permanent changes.
ENTRY BEHAVIOUR
Pupils have previously learned about living and non-living things and have observed changes in their surroundings such as plants growing, fruits ripening, water freezing, and ice melting.
This lesson builds on that knowledge by helping pupils understand that these changes can be classified as temporary changes and permanent changes based on whether they can be reversed or not.
INSTRUCTIONAL MATERIALS
The teacher will teach the lesson with the aid of:
1. Ice block and water
2. Candle and matches (for teacher’s demonstration)
3. Pictures of growing plants
4. Pictures showing ripe and unripe fruits
5. Rubber band
6. Balloon
7. Whiteboard and marker/chalkboard and chalk
8. Charts showing temporary and permanent changes
9. Basic Science textbook
10. Real objects from the environment showing different types of changes.
METHOD OF TEACHING
Choose a suitable and appropriate methods for the lessons.
Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON
LESSON 1 – INTRODUCTION
Nature includes everything around us such as plants, animals, air, water, soil, and weather. These things do not always remain the same. They change from time to time.
A change in nature is any alteration that occurs naturally in living and non-living things in our environment. Some changes happen quickly, while others take a long time.
Examples of Changes in Nature
1. Change from day to night
2. Change from rainy season to dry season
3. Growth of plants from seeds
4. Growth of animals from young ones to adults
5. Falling and growing of leaves on trees
6. Changes in weather conditions
TEMPORARY AND PERMANENT CHANGE
Changes in nature can be grouped into two main types:
1. Temporary Changes
2. Permanent Changes
LESSON 2 – TEMPORARY CHANGES
A temporary change is a change that can be reversed. The object can return to its original state.
Examples of Temporary Changes
1. Ice melting into water
2. Water freezing into ice
3. Inflating a balloon
4. Stretching a rubber band
5. Water changing into water vapour and back to water
Characteristics of Temporary Changes
1. Can be reversed.
2. No new substance is formed.
3. Original form can be restored.
PERMANENT CHANGES
A permanent change is a change that cannot be reversed. The object cannot return to its original state.
Examples of Permanent Changes
1. Burning of paper
2. Cooking of food
3. Ripening of fruits
4. Growth of plants
5. Rusting of iron
Characteristics of Permanent Changes
1. Cannot be reversed.
2. A new substance may be formed.
3. Original form cannot be restored.
LESSON 3 – IMPORTANCE OF CHANGES IN NATURE
1. They help plants grow.
2. They provide water through rainfall.
3. They help living things adapt to their environment.
4. They support the cycle of life.
5. They make the environment balanced.
DIFFERENCES BETWEEN TEMPORARY AND PERMANENT CHANGES
1. A temporary change can be reversed, while a permanent change cannot be reversed.
2. In a temporary change, the original form can be restored, while in a permanent change, the original form cannot be restored.
3. A temporary change does not produce a new substance, while a permanent change may produce a new substance.
4. A temporary change lasts for a short time, while a permanent change lasts for a long time or forever.
5. Melting ice is a temporary change, while burning paper is a permanent change.

SUMMARY
Nature is everything around us, such as plants, animals, water, air, land, and weather. Changes occur in nature every day. Some changes last for a short time, while others last forever.
Changes in nature may be temporary or permanent. Temporary changes can be reversed, while permanent changes cannot be reversed. Understanding these changes helps us explain many events that occur in our environment.
Pupils learned that changes in nature are natural events that occur in the environment. They identified examples such as day and night, seasons, and plant growth, and discussed their importance.
PRESENTATION
To deliver the lesson, the teacher adopts the following steps:
1. The teacher displays objects such as ice, water, a balloon, and pictures of growing plants and asks pupils to identify them.
Pupils’ Activities: The pupils observe and identify the objects.
2. The teacher asks pupils to mention changes they have observed in their environment.
Pupils’ Activities: The pupils mention examples such as melting ice, growing plants, and ripening fruits.
3. The teacher explains the meaning of changes in nature as changes that occur in living and non-living things in the environment.
Pupils’ Activities: The pupils listen attentively.
4. The teacher explains temporary changes and gives examples such as melting ice, inflating a balloon, and stretching a rubber band.
Pupils’ Activities: The pupils identify other examples of temporary changes.
5. The teacher explains permanent changes and gives examples such as burning paper, cooking food, ripening fruits, and growth of plants.
Pupils’ Activities: The pupils mention additional examples of permanent changes.
6. The teacher demonstrates a temporary change by allowing ice to melt and discusses what happens.
Pupils’ Activities: The pupils observe and describe the change.
7. The teacher discusses the differences between temporary and permanent changes.
Pupils’ Activities: The pupils participate in the discussion and provide answers.
8. The teacher writes examples of temporary and permanent changes on the board.
Pupils’ Activities: The pupils copy the notes into their notebooks.
9. The teacher asks oral questions to assess pupils’ understanding of the lesson.
Pupils’ Activities: The pupils answer the questions correctly.
10. The teacher summarizes the lesson by revising the meaning, examples, and differences between temporary and permanent changes.
Pupils’ Activities: The pupils participate actively in the summary.
CONCLUSION
To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
