Here's a post with an annotated list of books and web sites for studying shadows. Also, this picture gives me an idea for a fun photo op for our unit. The kids could hold up signs to make the words Rosalind Franklin STEM Elementary and or their own names
Except we take two pictures, and one has "i love" on their arm and in the second photo it's the other friend with "you" on their arm. Or maybe infront of a mirror with "you" backwards so it looks proper.
