Summarize this article for a 10 year old
The freezing point depression osmometer is an osmometer that is used in determining a solution's osmotic concentration as its osmotically active aspects depress its freezing point.

In the past, freezing point osmometry has been used to assess the osmotic strength of colloids and solutions. The osmometer uses the solution's freezing point depression to establish its strength. It is also used to determine the level of osmotically appropriate body fluid in various chemicals dissolved in the blood using the relationship in which a mole of dissolved substance reduces the freezing point of water by 1.86 °C (35.35 °F). The freezing point depression osmometer is also used in various medical practices, including pharmaceutical manufacturing, quality control laboratories, and clinical chemistry.
