- Educational Resource Centre Scheme of Work
- NAPPS National Unified Scheme of Work
- Online Information from: ScienceDirect.com – Chemical Control
- Relevant Textbooks
Instructional Materials
The teacher will teach this lesson with the aid of:
- Sample pesticide container (empty and clean).
- A picture/chart showing pests and weeds.
- A hand sprayer for practical demonstration.
- A measuring cup or small container.
Rationale for the Lesson
This lesson helps pupils understand how chemicals can effectively control crop weeds, pests, and diseases. It is crucial for sustainable agriculture, ensuring improved crop yield and food security.
Prerequisite/Previous Knowledge
Pupils have learned about cultural control methods and can identify common crop weeds, pests, and diseases.
Instructional Procedures
To deliver this lesson, the teacher will adopt the following steps:
| Content Development | Time | Teaching Method | Teaching Strategy | Teacher’s Activity | Pupils’ Activity | Learning Point |
|---|---|---|---|---|---|---|
| Step 1: Introduction | 5 mins | Set Induction | Interactive Questioning | Asks pupils to recall the cultural control of pests and diseases from the previous lesson. | Respond and share answers. | Crop pests and diseases can be controlled in different ways. |
| Step 2: Explanation of Chemical Control | 10 mins | Lecture | Demonstration | Explains what chemical control means and how it is used in farms. Shows a clean pesticide container and sprayer. | Listen, observe, and take notes. | Chemical control involves using chemicals to kill or prevent pests and weeds. |
| Step 3: Practical Demonstration | 10 mins | Guided Practice | Hands-On Activity | Demonstrates mixing water with a pesticide (pre-determined safe demonstration). Explains safety measures. | Observe and participate in measuring and mixing. | Proper application of pesticides improves safety and efficiency. |
| Step 4: Group Activity | 5 mins | Collaboration | Group Discussion | Divides pupils into groups to list 3 common pesticides they know or have seen. | Work in groups and share findings. | identify common chemical controls. |
| Step 5: Note Taking | 5 mins | Writing | Guided Learning | Dictates a concise note for pupils to copy. | Copy the note into their books. | document the main points of the lesson. |
| Step 6: Evaluation | 3 mins | Questioning | Interactive Assessment | Asks questions to evaluate their understanding. | Answer questions orally. | understanding is assessed. |
| Step 7: Conclusion | 2 mins | Summary | Recap | Summarizes the lesson and emphasizes safety in chemical use. | Listen attentively. | Safety and knowledge are key in farming practices. |
Lesson Content
Chemical Control of Crop Weeds, Pests, and Diseases
Chemical control involves using pesticides, herbicides, or fungicides to manage agricultural pests and diseases.
- Examples of Chemicals:
- Pesticides: For insects and other pests.
- Herbicides: For killing weeds.
- Fungicides: For preventing or controlling fungal diseases.
- Safety Measures:
- Always read the label on the chemical container.
- Wear protective clothing when applying chemicals.
- Store chemicals out of reach of children.
Lesson Evaluation
To evaluate the learning, the teacher asks pupils to:
- Define chemical control in agriculture.
- Mention two examples of chemicals used for pest control.
- State one safety rule to follow when using chemicals on a farm.
- Explain why it is important to control crop pests and weeds.
- Demonstrate (or describe) how to mix a simple pesticide solution.
Note for Teachers Using This Lesson Plan
This lesson introduces pupils to the concept of chemical control in farming. Ensure demonstrations are age-appropriate and follow safety guidelines strictly. Emphasize the importance of responsible chemical use. Happy teaching!
