Objective: To teach about substances, why separation from mixtures is needed

Subtopics to be covered:

- How a solution is formed and what is saturated solution

- Methods of seperation

Learning Outcome:

- Students can identify and classify the various methods of seperating substance (Threshing, winnowing, evaporation, etc.)

- Students will be able identify when a particular method of seperation is used (ex: when is sieving, handpicking, winnowing , etc. used)
