Lesson Content

Units and Symbols of Temperature

Temperature is a measure of how hot or cold something is. It is indeed measured using specific units and symbols. Below are common units and their symbols:

Units of Temperature:

Thes include:

1. Degree Celsius (°C)
2. Degree Fahrenheit (°F)
3. Kelvin (K)
4. Rankine (°R)
5. Réaumur (°Re)
6. Newton scale (°N)
7. Delisle scale (°De)

Symbols of Temperature:

The following are:

1. °C for Celsius
2. °F for fahrenheit
3. K for Kelvin
4. °R for Rankine
5. °Re for Réaumur
6. °N for Newton scale
7. °De for Delisle scale

Teaching Methods

To deliver this lesson,‌ ⁤the teacher will⁤ adopt⁤ the following methods: Set Induction, Question and Answer, Lecture, Exhibition, Hands-on, Practical engagement, Writing, Individual practice, Questioning, Group discussion, Recap, Summarization

Instructional Procedures

To deliver this lesson, the teacher will adopt the following steps:

Step 1: Introduction

Time: 5 mins
Teaching skill: Set Induction
Teacher’s Activity: Teacher asks pupils how we measure hotness or coldness of an object.
Pupils’ Activity: Pupils respond with examples like weather or body temperature.

step 2: Clarification of Temperature Units

Time: 10 mins
Teaching Skill: Explanation
Teacher’s Activity: Teacher explains temperature units (°C and °F) and shows them on a chart.
Pupils’ Activity: Pupils observe and listen.

Step 3: Demonstration of Temperature Scales

time: 10 mins
Teaching Skill: Demonstration
Teacher’s Activity: Teacher shows a thermometer and identifies °C and °F scales.
Pupils’ Activity: Pupils handle the thermometer and identify scales.

Step 4: Note-taking

Time: 5 mins
teaching Skill: Writing
Teacher’s Activity: Teacher dictates a short note for pupils to copy.
Pupils’ activity: Pupils copy the note into their notebooks.

Step 5: Evaluation/Review

Time: 5 mins
teaching skill: Questioning
Teacher’s Activity: Teacher asks pupils to name units and symbols of temperature.
Pupils’ Activity: Pupils discuss in groups and answer.

Step 6: Conclusion

Time: 5 mins
Teaching skill: Recap
Teacher’s Activity: Teacher summarizes the lesson and reinforces key points.
Pupils’ Activity: Pupils listen and ask final questions.

Lesson Keywords

• Temperature – A measure of how hot or cold something is.
• Celsius (°C) – A unit of temperature, where 0°C is the freezing point of water and 100°C is the boiling point.
• Fahrenheit (°F) – A unit of temperature, where 32°F is the freezing point of water and 212°F is the boiling point.
• Kelvin (K) – The base unit of temperature in the international System of Units (SI), where 0 K is absolute zero.
• Thermometer – An instrument used to measure temperature.

Lesson Evaluation

To evaluate the learning, the teacher asks pupils to:

1. Define temperature in their own words.
2. Name two units of temperature and their symbols.
3. Draw the symbol for degree celsius.
4. Explain the use of temperature units in weather forecasts.
5. Mention any two instruments used to measure temperature.

Assignment/Homework

1. Research and write down the boiling and freezing points of water in both Celsius and Fahrenheit.
2. Draw a well-labeled diagram of a thermometer, indicating the Celsius and Fahrenheit scales.
3. List five daily activities where temperature measurement is significant.

Differentiation

• For slower learners: Provide simplified charts with only Celsius and Fahrenheit scales. Pair them with advanced learners for peer support.
• for advanced learners: Challenge them to research and present on the Kelvin scale and its relevance in scientific measurements.
• For visual/auditory/kinesthetic learners: Use visual aids like thermometers and charts, explain concepts audibly, and allow hands-on practice with thermometers under supervision.

Note for Teachers

Ensure pupils handle the thermometer carefully during the demonstration. Encourage group discussions to enhance peer learning. Happy teaching!
