-Changes in plants e.g Leaf fall
Flower and fruits
Instructional Materials :
• A growing plant
• Explanatory posters/pictures
• Explanatory videos
- Scheme of Work
- Online Information
- 9 Year Basic Education Curriculum
Previous Knowledge :
The pupils have previous knowledge of Changes in nature Types of changes
Behavioural Objectives : At the end of the lesson, the pupils should be able to
- Narrate how simple plant grow
- Explain how seeds turn to young seedling
- Say that the upper part of the plant that is above the soil is the shoot
- Be aware that the lower part of the growing plant that is in the soil is called the root
CHANGES IN PLANT
Plants are also living things, they experience changes too as they grow. Most changes in plants are permanent changes.
Using Maize as an Example.
When a maize seed is planted into the soil, after some time, we experience change as the seed begins to grow, it changes from seed to seedlings. We experience increase in growths and the leaves keep broaden itself and greenish in colour, this is another change, after some time it will start producing fruits and the leaves of the corn turns yellow and brown before it is harvested by the farmer. These are different changes in plant.
Examples of Changes in Plants
1. The seeds turn into seedlings when growing.
2. Increase in height.
3. Broaden leaves.
4. Changes from flowers to fruits.
5. Increase in fruit sizes.
6. Change from immature (unripe fruits) fruits to matured fruits (ripe fruits).
7. Green leave turn yellow.
8. Yellow leaves turning brown.
9. Leaves falls.
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
- The upper part of the growing seed that is above the soil surface is called the………
- The lower part of the plant that is deep down the soil is called the……..
- Seed changes into….. when they are fully grown
- Why do green leaves turn yellow
The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.
The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.
He or she does the necessary corrections when and where the needs arise.
