Grandma approved! My 6 year old granddaughter and I were discussing solutions (actually "potions") so now I can give her a scientific explanation. This was very helpful! Thank you!
But then what happens to water molecules when they are evaporated? How do they even evaporate on the molecular level? Why don’t the sodium or chlorine ions also become a gas?
Thank you, great video!! Can you please explain how water moves soluble nutrition to cells in the body? For example, Salt. Since salt is dissolved in water; so, when a cell needs salt, does a cell need a stronger charge than water in order to pull sodium and chloride?
You left us hanging about the salt dissolved in water; didn't give us a conclusion - how/why the sodium and chloride went back to salt and didn't stay separate when the water evaporated. Are we talking 'valences'? Oxygen has a stronger valence and thus is better able to break up molecules?
2:38: 'The amazing thing about soil is that it's at an interface zone.' This is actually a very interesting observation. I hadn't really thought about it that way before. I've been reading a bunch of permaculture stuff, and they talk about how useful boundaries can be - but soil itself is all one big boundary, isn't it? A new way of looking at things. XD
