NanoSolutions Activity

The objective of this activity is to illustrate the idea of “nano”, or “one billionth”, through decreasing concentrations of a solution. This is done by using food coloring to create solutions that are one part per billion of solution. One part per billion is equivalent to one nanogram per milliliter.
