WHO WHEN WHERE WHAT WHY (1-3) The description of the experiment Franklin and his son In a shed in the fields A kite experiment To prove lightning and electricity are the same On a rainy day in June,1752

(4) The materials needed (1-3) The description of the experiment A kite A key A condenser Strings A silk ribbon To carry the things into the sky To feel the electric shock To make a kite To collect and store electricity To make a kite

1.Fix a piece of sharp metal to the kite. 3.Tie a ribbon to the string. 2.Fasten a key to the end of the string. 4.Fly the kite when a thunderstorm appears. (5 — 6) The steps of the experiment The materials needed (1-3) The description of the experiment (4)

F In 1752 scientists already knew what electricity is. Franklin was helped by a friend to do the experiment. Franklin made the kite of silk because wet silk does not conduct electricity. A condenser was used in experiment to store electricity. The key tied to the string was put into the door to stop the kite from flying away. T T F F
