Primary Sources in Science Classrooms: Mapping the Ocean Floor, Marie Tharp, and Making Arguments from Evidence (Part 2)

Posted by: Danna Bell

Textbooks and teachers often tell students about German scientist Alfred Wegener who went public in 1912 with his theory of continental drift. The scientific community did not widely accept Wegener's ideas during his lifetime and often derided colleagues who entertained the theory. Wegener passed away in 1930. Even as Marie Tharp was creating maps in the 1950s, scientists were actively constructing ideas and compiling evidence related to seafloor spreading and magnetic striping.

Keeping Humanity’s Collective Memory Alive

Posted by: Danna Bell

I have never been to Syria. I had only read about and seen images of the ancient ruins in Palmyra. I knew the 2,000-year old Greco-Roman structures were falling apart and had been for centuries. I had, however, no personal experience with them. But late last month, when news reports detailed their destruction, I found myself very upset, and tried explaining why to my children.
