Franklin’s Experiment: How Much Is True?

Benjamin Franklin’s famous lightning experiment has introduced generations of children to science. 1.

The well-known story is that Franklin flew a kite during a storm in 1752. At that time, there was much interest in electricity. People wanted to know if lightning was really produced by electricity. 2. He raised the kite with a piece of string tied to it. A metal key was attached to the string. A flash of lightning hit the kite, and electricity was conducted through the string to the key. 3. This, he said, proved that lightning was a form of electricity.

For years, schools have taught this story and it has inspired us and taught us that scientific experiments are important to establish the truth and to contribute towards later scientific discoveries and inventions.

However, neither the story nor the details of the experiment are entirely true. Although it has been proved that Franklin’s experiment took place, more than one scientist has questioned what really happened. 4. But scientists all agree that if Franklin had actually touched the key, he would certainly have died from the electric shock.

Scientists often question accepted ideas because they want to establish the facts. Some have even questioned the story about the apple that fell on Newton’s head and led him to come up with his theory of gravity.

5. But in science, facts should be proved by experiments and research, and we should not always believe everything we read or hear — even if it is a great story.

A.Franklin was one of them.

B.The detail about the string and the key is true.

C.It’s true that many discoveries start with an experiment.

D.Admittedly, fiction is often more interesting than the truth.

E.Franklin then touched the key with his finger and got an electric shock.

F.However, new research suggests that the story may be fiction instead of fact.

G.This experiment proves beyond any doubt that lightning is an electric phenomenon.
