1. The document discusses different methods of separating mixtures including filtration, winnowing, sieving, and picking.
2. Filtration involves using a filter to separate solid substances from liquids. Sieving and sifting are used to separate solid mixtures where one component has smaller particles than the other.
3. Winnowing separates grains from chaff by throwing materials into the air and allowing the wind to blow away lighter particles. Picking can separate mixtures where the components are large enough to be identified and gathered by hand.

mixtures? Will it be easy for us to separate them?
Can we separate them through picking?
2. For Activity B, what are the materials/components of the
mixture? How did you separate them?
3. For Activity C, what are the mixtures you came up with
using the given materials? Can we separate them using
picking or manual separation?
• Analysis
12. In everyday life, we use several mixtures and one need to
separate useful components from the mixture. Thus, the
separation of substances is performed by various
methods like hand-picking.
Mixtures are combinations of two or more substances not
chemically bonded where each substance retains its
chemical entity and properties. One of the techniques of
separating mixtures is through picking. For instances, a
mixture of grains and corn can be separated through
picking by using our bare hands. When the components of
a mixture are slightly larger in size, it is easier for us to
pick and separate them.
• Abstraction

Winnowing is another way to separate mixtures. It
is the process of freeing (grain) from the lighter particles
of chaff, dirt, etc., especially by throwing it into the air and
allowing the wind or a forced current of air to blow away
impurities. Winnower is a tool used in this process of
separating mixtures called winnowing.
It is a farming method developed by ancient people
for separating grain from chaff. It is also used to remove
weevils or other pests from stored grain. Threshing,
which is the loosening of grain or seeds from the husks
and straw, comes before winnowing.

In your own words, describe briefly how winnowing
is done in separating mixtures.

58. • Abstraction
Filtration is the process of separating solid substances
from a liquid using a filter paper or any cloths that can be
used as a filtering medium. These solid residues are
trapped by the filter paper or cloth, which allow the liquid
substances to pass through in the process.
It is the process of separating an insoluble solid from the
liquid substance by allowing the liquid to pass through a
porous material. The porous material is usually a filter
paper. The method of separation applies only to
suspensions because solute and colloidal particles are too
small to be retained on the filter paper. In this process, the
filter paper allows the liquid to pass through it and retains
the solid particles. The solid is called the residue, while the
liquid is called the filtrate.
59. Application

filtration.
