Lesson on Skin Color

I saw this picture on a first grade blog last week for a demonstration during a lesson about Martin Luther King.  Click here to read the original post. I think is a good way for all the visual learners to understand what we mean when we teachers often say "we're all the same on the inside."  The white and brown shells represent skin color, the egg yolks are identical on the inside...heart, lungs, kidney, liver, etc.
