Bubbles are another fun way to learn about matter! A bubble is a thin sphere of liquid enclosing air. I blew bubbles from triangular and rectangular shaped wands, but the bubbles were still spheres. Do you know why? However, I did show my first grade scientists how to make a square bubble!
Then I cut off the bottom off a water bottle, placed a piece of fabric over the end, and held it in place with a rubber band. When I blew out the other end, a chain of bubbles was created.
Bubbles are iridescent- something that shines with many different colors when seen from different angles, like this shell.
