Bubbles!

Bubbles are a really fun way to introduce science to preschoolers. They all have experience with bubbles of some kind - either the kind you blow thru a straw or a bubble blower. So how do we turn something so common into WOW science?

Easy - come on and I'll show you.

Can you capture a bubble? I captured some bubbles with my friends this week. We learned a lot along the way. We captured bubbles with a LITTLE bit of water, paint and a squirt of soap. Mix this up - this is key. Most of my friends had gobs of paint on the bottom of their container that didn't get mix it. Then blow bubbles with a straw. The bubbles will be the color of the paint.Carefully place paper on top of the bubbles and you've captured bubbles!But let's not stop there! Can you make a square bubble? Grab a pipe cleaner and make it into a bubble wand with a square opening. Now try it in your favorite bubble solution. Does the bubble come out square?
** Science Content** Bubbles are only round - it is the least energetic shape and molecules are basically lazy. One of my favorite websites about bubbles is here.

But wait, there's more! One of my favorite ways to play with bubbles is to compare and contrast bubble solutions. Compare homemade bubbles to commercial bubbles (or any other kinds of bubbles you like) - which makes the most bubbles or the longest-lasting bubbles or the best-smelling bubbles?? There are lots of great questions kids can ask.

And just because I like to challenge you: What color do bubbles turn just before they pop?
