Science project idea on electricity and modern life.
Electricity Science Project Idea
If a man who lived a century ago should visit us, he would be much surprised at the many changes which have occurred since his tune.; Especially would he be amazed at those inventions which depend upon electrical energy.; Electricity was being studied by some of the scientists of his time, but probably none of them had the faintest idea of the practical importance that it would have. The first electric motor, a very inefficient one, was constructed in 1838, and it was not until 1871 that really efficient motors and dynamos were used.; Electric lighting on a commercial scale was used for the first time in Paris and London in 1877.; Think of the many things which this visitor from a previous century would see for the first time.; Make a list of the appliances of present day life which make use of electrical energy.
