9. Lesson Activity

10. Heating water
A small group of students followed the teacher’s instruction to gently heat some ice in a beaker
and take the temperature every minute. The students recorded their data and produced the
graph below.

11. Question 1. What do you think has happened in the
last 4 minutes?
 The temperature is rising rapidly.
Question 2. What might you see happening in the
first 4 minutes?
 The ice is melting.
Question 3. What do you think would happen if the
students went on heating the water?
 The water would probably start to boil

12. Read out and answer the following
questions based on the diagram shown
below:
Question 1. Describe the temperature in
the first 4 minutes while the ice is melting.
Heating
water

13. Question 2. Describe what is happening
according to the graph in words.
Heating
water

14. Question 3. Use your understanding of
the particle model to explain why the
temperature does not rise in the first 4
minutes.
Heating
water

15. Lesson Conclusion

16. Question 1:
Did you find the
questions in B easier
than the questions in
C. Why?

17. Question 2:
