In the story ‘The Wings of Icarus’, you read how Sun’s heat melted
the wax that was holding Icarus’s wings together. Did you think about
how this happened?

Do you know that sunlight contains heat energy that can benefit us in
many ways? Perform this experiment to know about this.

Materials required: a small piece of white paper and

a magnifying glass
Procedure:

1. Take the piece of paper and hold it near the ground.
2. Take the magnifying glass and hold it above the

paper in such a way that Sun’s rays get focused on
the paper at a spot.
3. Keep both your hands steady and observe what happens.

Observation: After 3 to 4 minutes, depending on the intensity of
Sun’s rays, the paper will start burning.

Conclusion: We get heat energy from Sun.

Now, refer to the Internet or the books in your school library to list
any four uses of heat energy.
