I found this demonstration to show some PS topics but I need help explain actually all the ideas that it demonstrates. "Bubbles have characteristic behaviors based on the arrangement of the atoms that determine their molecular structure. Investigate bubbles and the bonds that are behind their structure. Record and organize data to communicate findings in multiple ways." Question I need help with What gives bubbles longevity? Why is their shape spherical? Is it possible to create square bubbles? As you can see I don't have a strong PS Background! Need help!!!

Hi Anne,
I can help you with some of your questions, and I can recommend an excellent journal article that will explain some of the science behind soap bubbles.
Yes, bubbles are spherical, but they can be 'poured' into a cube to take on the appearance of a square. According to the article, they are not in a liquid or solid state of matter, but rather they are classified as a liquid crystal. The article also discusses this special state of matter and provides information about the molecular structure.
You can access and read the article at: Lighten Up Your Lessons: Matter, Optics and Bubbles.
I hope this helps.

Bubbles cannot be square because of the surface tension. Basically, a bubble is not strong enough to be square and hold that shape. When you blow a bubble, the air is equally distributed. A cool lesson to do is give the kids differnt objects to make the bubbles, wire coat hanger, straws, etc. This will demonstrate that no matter what you use, the bubble will always come out as a sphere.

Video Links for Bubble Bonanza: Designing Bubble Wands
These videos are great ways to help kids learn more about bubbles and become even more excited about designing bubble makers! While they can be watched at any time while you are engaged in the Bubble Bonanza unit, the 'See It!' boxes in some of the adventures indicate good times to watch specific videos.
