🧪 Science Experiment: Heating Ice

During an Integrated Science practical lesson, learners were investigating how temperature changes when ice is heated. At the start of the experiment, the temperature of the ice was –5°C. The ice was placed over a Bunsen burner and after a few minutes of heating, the temperature rose by 10°C.

Using a number line, show the temperature change and determine the final temperature of the ice after heating.

💡 How to Solve

Starting temperature: -5°C
Temperature rises by: +10°C
Calculation: -5 + 10 = 5°C

When temperature rises, we add (+). Move 10 steps to the right on the number line from -5.
