You have learnt that dark-colored clothes or surfaces heat up faster in the sun. That’s because dark colors absorb most of the sunlight that falls on them. That is why it is recommended that one should wear light color clothes in summer. But have you ever thought about the other colors – red, blue, green, or yellow? Do they all absorb heat the same way, or are some better at trapping sunlight than others?

Sir Isaac Newton discovered that sunlight could be split into a rainbow of colors – violet, indigo, blue, green, yellow, orange, and red. In this activity, you will explore how each of these colors absorbs heat differently and find out which one traps the most energy from sunlight.
