Introduction: The light of the Sun is very strong. If you use a magnifying glass to concentrate and direct the beam of light you can start a fire. Using the same heat we can do "solar writing".
Since this experiment involves fire you need an adult to help you with this experiment. Do not attempt to do this alone.
After discussing the energy of the Sun and the uses of the Sun for solar power try this experiment.
Note: pick a place where there is no danger of fire spreading - a patch or bare ground on a table top.
First the paper will start to smoke, then turn brown. A hole will burn through the paper. Some kinds of paper will catch fire.
The intense energy from the Sun has been harnessed by the concentration of light through the magnifying glass. This has generated enough heat to start the burning.
