Baby: Mommy, who is the new polar bear cub? Mom: His chromatography left him, so he is now in our mixture. Now we are a different compound of different elements. Baby: What's a chromatography mommy? Mom: A seperation of mixtures. It's passing a mixture through a stationary phase to be measured. Baby: Ooohhhhh! That's soooo coool! I want to be a chromatography! Mom: OH NO YOU DON'T! 

This is a rhyme we made to remember the difference between an element and a mixture: Elements give us excitment because they cannot be seperated. Compounds make us happy cause it is a pure substance made from two or more elements. Mixtures give us smiles because it’s a combination of two or more.
