CCS GRADE 6 Science

Filtration is a process that separates solid particles from a fluid (liquid or gas) by passing the mixture through a porous material that blocks the solids while allowing the fluid to pass through according to Biology Online. Think of it like straining pasta: the water passes through the holes of the strainer, but the pasta is retained.

Here's a more detailed breakdown:
The Goal: To separate a solid from a liquid or gas (or a supercritical fluid).

The Mechanism: A filter medium (like filter paper or sand) with tiny pores is used to block the solid particles while allowing the fluid to flow through.

Key Terms:
Filter Medium: The material that does the filtering (e.g., filter paper, sand, a membrane).
Filtrate: The fluid that passes through the filter.
Residue: The solid particles that are retained by the filter.

Examples:
Coffee brewing: Coffee grounds are trapped by the filter paper while the coffee liquid passes through.
Water purification: Filtration can remove dirt and other particles from water, making it cleaner.
Industrial processes: Filtration is used in many industries to separate materials.
The human body: Kidneys filter waste from the blood.

Handpicking mixture

Handpicking is a simple method of separating a mixture by physically picking out the desired components by hand. This technique is effective when the components of the mixture differ significantly in size, shape, color, or other readily distinguishable physical properties. It's best suited for small quantities and mixtures with clearly distinct components.
Examples of mixtures that can be separated by handpicking:
Stones from rice or other grains: Easily identifiable stones can be picked out from a pile of rice.

Separating Mixture
☺️☺️Decantation is the process of separation of liquid from solid and other immiscible liquids, by removing the liquid layer at the top from the layer of solid or liquid below
