Definition: A spherically contained volume of air or other gas, especially one made from soapy liquid.
Alright class, settle down, let’s take a look! We’ve got a tricky word today – “bubble.” The dictionary gives us a good start, don't you think? It says it’s “a spherically contained volume of air or other gas, especially one made from soapy liquid." Let’s break that down nice and slow. "Spherically contained" means round, like a ball – can anyone show me a sphere with their hands? (Pause for response) Excellent! And “volume of air or other gas” just tells us it's filled with something - like the air we breathe, or maybe even helium if you’ve ever seen a balloon. But what about that soapy liquid bit? That’s key! Think about blowing bubbles with soap and water. The soap is what makes them form those perfect, round shapes. It helps the air hold itself together. So, essentially, a bubble is a little sphere of something – usually air - held in place by a special substance, like soapy liquid. It’s a tiny world, floating and shimmering! Does that make sense? Any questions about our bubbly friend?
