IRAN JULY 2019

The Power of the Sun and how to measure it We did two different experiment for calculating the power of the sun with our teacher Mr Mahdi Rokni. In the first experiment, we used an A4 paper with an oil spot. We used a 100W light bulb. After that, we measured the amount of paper to the bulb.

For the second experiment, one of the teams stood in the middle so one side of the face was facing the sun and the other side was facing the bulb. Finally, we put the numbers in the formula we had learned before doing experiments and obtained the amount of solar power.
