Presentation

The lesson is presented in the following steps:

Step 1              : Introduction

The teacher introduces the lesson is by carrying out an activity that stirs the pupils’ curiosity. Say, the teacher walks into the class, greets the pupils, asks them to watch while s/he lights a candle. Soon after the candle finish burning, the teacher then asks the pupils what happened, where his/her candle has gone to. The teacher receives different answers (opinions) before telling them that the candle has simply changed! S/he then writes the topic on the board.

Step 2              : Definition of Terms

Following the introduction of the lesson, the teacher explains the changes in the candle. S/he explains that the candle changed from a (candle) stick to liquid candle (candle wax) and then changed from wax to a solidified wax again – but that the shape or form of the candle also changed from a candle stick to an irregular solid.

Following the explanation, the teacher asks the pupils the meaning of change. After some attempts, s/he writes the definition on the board and explains more thoroughly.

Definition of Change: A change is when something becomes different from its original form.

Step 3              : Examples of Change

Once the teacher has explained the meaning of change, s/he explains that things around us do not remain the same all the time. S/he lists and explains examples of changes around us:

Some of examples of changes around us include the following:

  1. Weather changes from hot to cool, windy to still or rainy
  2. Candle changes to wax
  3. Pieces of paper burn into ashes
  4. Wood burn into ashes
  5. New things become old
  6. Water turns to ice

(The teacher asks the pupils to name more while s/he writes them on the board)

Step 4              :  Types of Changes

Succeeding the examples of changes above, the teacher leads the pupils to categorize changes into the different kinds of changes.

First, s/he explains that all the changes around us – including the examples above – can be grouped into two. That means there are two types of changes. These are:

  1. Temporary Change
  2. Permanent Change

Step 5              : Temporary Change

A temporary change is a change that happens for a short time and can be reversed.

Temporary changes occur as a result of change in position or condition in the environment. Examples of temporary change are as follows:

  1. Water change to ice block when temperature is very low.
  2. Ice block change to water when temperature increase
  3. Chameleon change its colour when the colour of its environment change
  4. Cold water changes to hot water when heated
  5. Hot water change to cold water when taken from heat

(The teacher asks the pupils to name more while s/he writes them on the board)

Step 6              : Permanent Change

Permanent change is a change that cannot be reversed. When something is not reversible, then it is irreversible. Examples of permanent changes are:

  1. Trees cut into planks
  2. Cassava processed into garri
  3. A little child grown to an adult
  4. Yam changed to pounded yam
  5. Wood burnt into ashes

(The teacher asks the pupils to name more while s/he writes them on the board)

Step 7              : Note Writing

The teacher then gives the pupils the note (all italicized above) to copy. S/he monitors the pupils to ensure their handwriting is legible and in accordance with the school handwriting policy.

Step 8              : Evaluation

The pupils’ understanding of the lesson is evaluated by asking questions and making the pupils to carry out the sorting Activity 1.1 (contained in the attachment):

Step 9              : Summary

Once evaluation proves that the pupils understood the lesson and the objectives of the lesson has been met, the teacher review the lesson once again with the pupils

Step 10         : Assignment

The teacher, after the summary gives the pupils some homework based on the topic (questions included in the attachment file).

Step 11         : Conclusion

The lesson is concluded by marking, recording and returning the pupils’ notes and making corrections where necessary. The teacher, after the final correction tells the pupils the topic for the following (week’s) lesson – The Differences between Temporary and Permanent Changes. Thereafter, s/he groups the pupils into groups of five pupils to carry out the following Activity 1.2 in preparation for the following topic: Changes in Plants
