Science is almost always associated with electricity. In fact most scientific discoveries are based on science projects using electricity. The trouble is that not everyone regards electricity as the miracle it is any more. We have got so used to turning on a switch and flooding a room with light that the magic has gone out of the experience.

Maybe we have taken electricity so much for granted because we have grown up with it. Secure in the knowledge that we have to but hit the switch and lights will follow. The fact that a majority of the world’s population still does not have electricity in their homes is of little importance to us.

That’s why the Earth Hour project is important. Over 80 countries on all the continents in the world participated in the last Earth Hour event. At an appointed time every one switches off all the lights in their homes. It is an awareness drive for Global Warming being caused by human activities. So make sure that you do your part for the Earth next time we celebrate Earth Hour.

On the other hand science projects like this one on light intensity here will never be possible with out electricity. So make sure that you try it out when you can use electricity. Just make sure that you use it without wasting it. As with all man made resources even this one is non recyclable.
