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: Labomat – How to measure the temperature?
- Relevant Textbooks: “Basic Science and Technology for Primary Schools”
Instructional Materials:
The teacher will teach this lesson with the aid of:
- Thermometers (both Celsius and Fahrenheit)
- Ice water and hot water
- Charts of temperature scales
- Whiteboard and markers
- Measuring containers
Rationale for the Lesson:
Understanding how to measure temperature is important because it helps pupils make sense of temperature changes in their environment, such as whether something is hot or cold. This skill is used daily when cooking, working with appliances, and even understanding the weather. It also introduces the concepts of Celsius and Fahrenheit, both of which are used worldwide for scientific purposes.
Prerequisite/Previous Knowledge:
Pupils should already be familiar with the concepts of temperature, the use of thermometers, and the basic symbols for temperature measurement (°C and °F), having learned about the units and symbols in the previous lesson.
Instructional Procedures:
To deliver this lesson, the teacher will adopt the following steps:
| Content Development | Time | Teaching Method | Teaching Strategy | Teacher’s Activity | Pupil’s Activity | Learning Point |
|---|---|---|---|---|---|---|
| Step 1: Introduction | 5 mins | Set induction | Discussion and demonstration | Introduce the concept of measuring temperature. Show the thermometer and explain how it works. | Listen and observe. Ask questions about temperature. | Temperature is the measure of heat in an object. |
| Step 2: Explanation of Celsius | 7 mins | Explanation | Example and practice | Explain how to measure temperature in °C using an example (e.g., ice water). | Observe demonstration and take notes. | Temperature can be measured in °C (Celsius) using a thermometer. |
| Step 3: Explanation of Fahrenheit | 7 mins | Explanation | Example and practice | Show how to measure temperature in °F using an example (e.g., hot water). | Observe demonstration and take notes. | Temperature can be measured in °F (Fahrenheit) using a thermometer. |
| Step 4: Guided Practice | 10 mins | Guided Practice | Hands-on practice | Let pupils work in pairs to measure the temperature of various objects (ice water, hot water). | Work in pairs to measure temperatures using thermometers. | Measurement of temperature is a hands-on process requiring attention to detail. |
| Step 5: Note Taking | 5 mins | Independent Activity | Writing | Pupils write down the steps involved in measuring temperature in °C and °F. | Write notes on the board. | It is important to record measurements accurately. |
| Step 6: Evaluation | 4 mins | Question and Answer | Oral questioning | Ask pupils to answer questions based on the lesson content. | Respond to the teacher’s questions. | Measuring temperature in °C and °F is a practical skill. |
| Step 7: Conclusion | 2 mins | Conclusion | Recap and reflection | Summarize the key points of the lesson. Reinforce the importance of measuring temperature. | Summarize what they learned. | Accurate temperature measurement helps in daily tasks and experiments. |
Lesson Content:
Measuring Temperature of Objects in °C and °F
Temperature is a measure of how hot or cold an object is. We can measure it using a thermometer. There are two main scales for measuring temperature: Celsius (°C) and Fahrenheit (°F).
Measuring temperature of objects in Celsius (°C):
- To measure temperature in °C, place the thermometer in or near the object you want to measure.
- Wait for a few seconds until the thermometer gives a steady reading.
- For example, the temperature of ice water is 0°C, and the temperature of boiling water is 100°C.
Measuring temperature of objects in Fahrenheit (°F):
- To measure temperature in °F, the same steps apply, but the scale is different.
- For example, ice water will be at 32°F, and boiling water will be at 212°F.
Lesson Evaluation:
To evaluate the learning, the teacher asks pupils to:
- What is the unit of measurement for Celsius and Fahrenheit?
- How do you measure the temperature of an object in °C?
- If you placed a thermometer in boiling water, what temperature would you expect to see in Celsius and Fahrenheit?
- What is the difference between the Celsius and Fahrenheit scales?
- How can you ensure the thermometer reading is accurate?
Note for Teachers Using This Lesson Plan:
While using the thermometer, remind the pupils to be careful as it may break easily. Always emphasize the importance of reading the thermometer at eye level to avoid errors. This lesson is a great opportunity to get pupils involved with hands-on activities. Encourage them to ask questions and experiment with different objects. Happy teaching!
