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.
