Answer:
With savings, you are placing your cash into an account where it's going to accrue interest but its trajectory is mostly a small line upward. It is safe and you may no longer lose it, as it's far insured through the FDIC.
With investing, you purchase pieces of agencies or bonds or commodities and the cost of these pieces rises and falls as the value of the agencies, bonds, or commodities rises and falls. So, instead of the small line upward as visible with savings, it looks greater like a roller coaster. That could mean you gain lots of it may suggest you lost lots.
