During our S.T.E.M workshop with our Mastery Charter School students, we first went over in detail how the "Scientific Method" works. Afterwards, we had the students name "Common household items" that we have used in previous workshops. They were instructed to identify the acidity/base of that item, along with that identifying the chemical name for those items as well. For example: Baking Soda, which we have used several times is "Sodium Bicarbonate". To conclude the lesson, the students conducts a short experiment called "Stackable Liquids in a bottle", which was done using common household items. Those items consist of rubbing alcohol, vegetable oil, corn syrup, dishing washing liquid and water. This specific experiment was also bases on density. Density measures how much mass is contained in a given unit volume (Density = Mass / Volume). Think of mass as the measure of how much stuff there is in an object or liquid. Volume is the portion or how much there is of the object. Density is a measure of how tightly that stuff is packed together.
