Read the text. Tick (✓) the things that Alexander Graham Bell experimented with.
A famous inventor
When Alexander Graham Bell was 29, he made one of
the most important inventions in the history of the world:
the telephone. A year later, he started the Bell telephone
company. It became very successful. He became
businessman and earned a lot of money from his
lephone company.
But Alexander Graham Bell wasn't so interested in
money. He was interested in making inventions. He
always wanted to learn, and to try and create new
things. He never stopped thinking of new ideas. He used
his money to open laboratories with teams of engineers
who could help him make his dreams come true.
Sell was also fascinated with propellers and kites,
and did lots of experiments with them. In 1907, four
years after the Wright Brothers made their first flight,
Bell formed the Aerial Experiment Association with
our young engineers. Their plan was to build planes.
The group was successful. Their plane named Silver
Cart made the first successful flight in Canada on 23
February, 1909.
