So, as I mentioned yesterday, I did not get around to posting my Sunday topic page which means you did not get some great stories and videos about this week’s topic… so here you go! The first is from SciShow Kids on the science of bubbles, the second is a song from Laurie Berkner Band, and the third a story. One more story to look up is The Bubble Factory, this is one of my favorite bubble stories!
Bubbles… kids love them, pets love them and lets admit it … adults love them. But, why teach about bubbles? First… because they are fun. Who doesn’t like to learn about things that are fun? And, for kids, this is exactly the motivation they need to learn… a love of a topic, and wanting to know the why behind it.
So, lets first talk about the why. Bubbles are a thin film of soapy water enclosing air. The bubble forms into the shape of a sphere because this shape uses the least amount of surface tension. When you break the surface tension, you pop the bubble!
You can use bubble solution or you can make your own. Here is a recipe for bubble solution that does not utilize glycerin, the use of glycerin increase the elasticity of the solution.
- 4 Tbsp of water
- 1 Tbsp of dish soap
- 2 Tbsp of sugar
- put the water into a bowl
- add the soap and mix
- sprinkle in the sugar and gently mix
- now test it out
Now go blow some bubbles. Don’t have a bubble wand? Make one! you can use pipe cleaners, straws or even just loops of string on a stick. Get creative. Try different shapes.
