My class studied outer space in November. I finally got around to photographing their constellations. We tried some by gluing random stars on the page and then trying to imagine the pictures, but that was too hard for my 3-5 year olds. So we drew pictures with white oil pastels and then put stars on the lines and corners. This was lots of fun, and when I turn off the lights in the classroom, you can see the stars, not the lines. Very cool, considering that they are not glow-in-the-dark stars.
