In this chapter, you will learn about matter and its different forms. Matter can exist as a solid, liquid, or gas. You will also learn how to classify objects based on their states of matter. Another topic is changes in states of matter for water.
You will explore how water can change from a solid (ice) to a liquid (water) to a gas (water vapor). You will also learn how heat can cause these changes in states of matter.
Activities will be done to help you understand these concepts better.
• State that matter exists in the form of solid, liquid and gas
• Classify materials or objects based on the states of matter
• Characterise properties of solid, liquid and gas by carrying out activities
• Make generalisation that water can exist in three states of matter by carrying out activities
• Explain the observations on states of matter through written or verbal forms, sketches, ICT in a creative way
• Describe the changes in states of matter for water by carrying out activities
• Explain with examples the changes in states of matter when it gains or loses heat by carrying out activities
• Relate the changes in states of matter for water in the formation of cloud and rain
• Explain the observations on changes in states of matter for water through written or verbal forms, sketches, ICT in a creative way
