Reference Materials:
The following resources were used in planning this lesson:
- 9 – Years Basic Education Curriculum
- Abuja Educational Resource Centre Scheme of Work
- NAPPS National Unified Scheme of Work
- Online Information from: Wikipedia – Fahrenheit
- Relevant Textbooks: “Basic Science for Primary Schools” by A. Teacher
Instructional Materials:
The teacher will teach this lesson with the aid of:
- A thermometer
- Visual aids showing Fahrenheit scale
- Chalkboard and markers
- Worksheets for practice
Rationale for the Lesson:
Understanding the units and symbols of temperature in the Fahrenheit scale helps students in their everyday life, such as when reading weather forecasts or measuring temperature in science experiments. It also serves as a foundation for learning about other temperature scales such as Celsius.
Prerequisite/Previous Knowledge:
Pupils should be familiar with the basic concept of temperature and have encountered the Celsius scale in previous lessons.
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 | Demonstration | The teacher will show a thermometer and ask pupils what they know about temperature scales. | Pupils will respond and share their prior knowledge about temperature. | Temperature can be measured using different scales. |
| Step 2: Explanation of Fahrenheit Scale | 7 mins | Direct Instruction | Visual Aid | The teacher will explain that the Fahrenheit scale is commonly used in the United States and show the symbol for Fahrenheit (°F). | Pupils will take notes as the teacher explains the Fahrenheit scale. | Fahrenheit is a unit of temperature. |
| Step 3: Units and Symbols of Fahrenheit | 8 mins | Guided Practice | Discussion & Examples | The teacher will introduce five units and symbols of Fahrenheit: 32°F (freezing point), 98.6°F (normal body temperature), 212°F (boiling point), etc., using a chart. | Pupils will copy down the units and symbols, discussing their meanings. | The Fahrenheit scale has standard reference points like freezing and boiling. |
| Step 4: Calculating Temperature in Fahrenheit | 10 mins | Interactive Learning | Example Problems | The teacher will explain how to calculate temperature in Fahrenheit by using the formula: (Celsius × 9/5) + 32 = Fahrenheit. The teacher will work through an example. | Pupils will solve a similar problem in pairs with guidance from the teacher. | Temperature can be converted between Celsius and Fahrenheit. |
| Step 5: Note Taking | 5 mins | Independent Work | Note Review | The teacher will ask pupils to review and write down key points from the lesson. | Pupils will write down the units, symbols, and calculation methods in their notebooks. | Taking accurate notes helps reinforce learning. |
| Step 6: Evaluation | 3 mins | Question and Answer | Recap & Review | The teacher will ask a few questions to assess pupils’ understanding of the Fahrenheit scale. | Pupils will answer questions based on the lesson content. | Pupils demonstrate understanding of the topic. |
| Step 7: Conclusion | 2 mins | Summary | Reflection | The teacher will summarize the key points of the lesson and give an assignment for further practice. | Pupils will listen and ask questions if needed. | The Fahrenheit scale has specific units and symbols. |
Lesson Content:
Units And Symbols of Temperature Degree Fahrenheit
The Fahrenheit scale is used to measure temperature in some parts of the world, especially in the United States.
Symbols and Units in Fahrenheit:
- 32°F – Freezing point of water.
- 98.6°F – Normal human body temperature.
- 212°F – Boiling point of water.
- 0°F – Very cold temperatures.
- -40°F – The point where Fahrenheit and Celsius scales are equal.
How to Calculate Temperature in Fahrenheit:
To convert Celsius to Fahrenheit, use the formula:
(Celsius × 9/5) + 32 = Fahrenheit.
Example: Convert 25°C to Fahrenheit:
(25 × 9/5) + 32 = 77°F.
Lesson Evaluation:
To evaluate the learning, the teacher asks pupils to:
- What is the freezing point of water in Fahrenheit?
- What is the normal body temperature in Fahrenheit?
- How do you convert Celsius to Fahrenheit?
- Give an example of a temperature in Fahrenheit.
- Why is it important to know the Fahrenheit scale?
Note for Teachers Using This Lesson Plan:
Ensure that all pupils participate during the question and answer session. Encourage collaboration when solving the practice problems. Make sure to provide additional examples for pupils who may need extra help understanding the calculation process. Happy teaching!
