In Sciences, my 7th graders were asked to present a PPt on "My Scientist". Each chose a different scientist (except Telma) and then their teacher of English took it one step further and asked them to do the same in English! Here is the result :) Alfred Wegener, by Telma

1.  My Scientist …
Alfred Wegener
Date of birth: November 1, 1880
Date of death: November 2, 1930
German nationality :
- Meteorologist
- Led several expeditions to Greenland
laid the foundations of continental drift

2. • Alfred Wegener was a German meteorologist, who presented
a theory about the continents.
• He said that continents had been united in the past, as a
continental mass, and have been separated slowly to the
positions they occupy today.
• Alfred Wegener called it Pangaea supercontinent and
Panthalassa to the only ocean around it that existed millions
of years ago.

3. • Alfred Wegener’s arguments:
• - The morphological shape of the continents is
complementary
• - Identical in continent - paleontological fossils that are
separated today
• - Paleo climate - Traces of glaciers in various continents
that today have different climates
• - Identical geological – rocks
Wegener's theory was not accepted in the scientific
community in that era because the mechanism remained
of continental drift remained elusive; as he was not a
geologist, his ideas attracted few supporters and he had
no great prestige.
