In this chapter, you will learn about heat and temperature, how to measure temperature, and the different ways heat can be transferred.
You will also explore how heat affects different materials and the concept of thermal expansion and contraction. By the end of this chapter, you should be able to identify the three types of heat transfer and explain how heat moves through different materials and mediums.
• State the meaning of heat and temperature
• Measure temperature using the standard tool and unit with the correct techniques
• Use space-time relationship to observe the changes of temperature when ice is heated and determine the freezing point and boiling point of water by carrying out activities
• Describe the changes of water temperature when hot water is cooled down to room temperature
• Conclude effects on materials when they gain and lose heat by carrying out activities
• Provide reasoning on the importance of application of expansion and contraction principle of materials in daily life
• Explain the observations about heat and water temperature through written or verbal forms, sketches, ICT in a creative way
