Summary:
Today we discussed the concept of a “mixture” as it relates to chemistry. We defined it as “two or more elements or compounds mixed together, but not not bonded.” A great example would be something like orange juice. Orange juice contains several different compounds (i.e. water, vitamin-C, sugar, etc.) that each retain their own physical properties. As such, you would need several formulas to describe Orange Juice (i.e. H₂O, C₆H₈O₆, C₁₂H₂₂O₁₁, etc.)

In class, after our discussion, students worked on a packet (posted below) that had them investigate several different mixtures, including air, rocket fuel, and Coca Cola.
