Drawing 2: The Nile River (Free Preview)

This is a preview lesson. Please purchase the course before starting the lesson.

In this lesson we will meet two men from Greece: Strabo and Eratosthenes.  Strabo wrote a book about geography in which he stated that astronomy and geography were related.  Eratosthenes then calculated the size of the Earth by comparing the sizes of shadows in different cities.

The follow-up activity will give you more practice using your drawing tools (compass and protractor).
