How did Darwin get interested in Science &Nature?
As a child his favorite pass times were climbing trees,catching rats, playing with dogs and taking long walksin the country to collect whatever he could find
Charles did not do well at school
At age 13 he and his brother set up a chemistry lab in the tool shed of their garden where he learnt the basics of scientific experimentation
As he grew older he became interested in bird watching,collecting minerals, beetles and taxidermy (collecting andstuffing specimens)
Darwin’s education
