Ms. Mills and Bubbles
We were grateful to have Literacy Leader (and Math Coach) Ms. Katrina Mills on the bookmobile this afternoon! She had some outstanding BUBBLE experiments for our patrons. Everyone had a great time...it was so interesting to see all of the different ways to make bubbles AND to see all of the different ways to make bubble wands.
No matter what shape the wand was, though, the bubble was still a sphere...Ms. Mills' daughter, Avery, was on hand to explain why: Bubbles are round — spherical — because there is an attractive force called surface tension that pulls molecules of water into the tightest possible groupings. And the tightest possible grouping that any collection of particles can achieve is to pack together into a sphere.
