Why Is the Sky Blue?

The Isabella Stewart Gardner Museum is home to some of the world's most valuable works of art. In this episode, Michelle Groe gives us a tour and talks about value in art. If you decide to make your own paint from rocks or plants, we would love to see a picture of it. We will be back in two weeks with an answer to that age-old question, why is the sky blue? And our guest is going to be the woman who leads educational programs at NASA.
