science 6 Quarter 1 topic week 1
Today we will learn grade six  topic in science quarter 1. what is science you will ask? It is an topic that systematic study of the structure and behaviour of the physical and natural world through observation,experimentation and the testing of theories against the evidence obtained " the world of science and technology"

First Subject MATTER a mixture is a combination of two or more subtances. In some mixtures, you can identify each of the subtances composing it.Mixtures can be seperated into its different components.

SOLUTIONS AND OTHER UNIFORM MIXTURES Uniform or homogeneous mixtures are liquid mixtures in wich you cannot clearly see the components or ingredients Example a cup of coffee or a tea.The main component is called the solvent(usually in greater amount) while the dissolved additive is called the solute(usually in lesser amount)

SOLUBILITY When you put sugar and salt in separate glasess with same amount of water it eventually dissolves but the sugar dissolves and do not leave a trace behind since it is more soluble than salt if you will look at the salt it is still big chuncks at the bottom.

MISCIBILITY liquids like vinegar,soy sauce,and alcohol mix well in the water. They are miscible in water however not all liquids does mix in the water.The immiscible one is the liquid that does not mix in the water like the oil.

OTHER TYPES OF HOMOGENEOUS MIXTURES

A. Gaseous air is a mixture of different kinds of gases .Our athmosphere ,or the air surrounding the earth is composed of 78% nitrogen and 21% oxygen and the remaining 1% is carbon dioxide argon and many other gases. B.Solid in these solid mixtures of metals, the components metals cannot be individually identified. The are also called alloys.

NON- UNIFORM MIXTURES A mixture in wich you can easily distinguish the components or wherein the components retain their phases is called a non-uniform it is a mixture that if you mixed you will still see it like the egg soup you can still see the carrots,the egg white,and more.

SUSPENSIONS AND COLLOIDS

SUSPENSIONS are heterogeneous mixtures with particles suspended in a gas or liquid. When shaken or stirred, the particles in a suspension seem to evenly to be evenly distributed throughout the mixture However the particles still remain visible as they are suspended within the liquid.

COLLOIDS It is the same as an suspesion but colloids are evenly distributed beu when look under the microscope you will see the uneven parts of itin a disphersing medium. TYNDALL EFFECT it is the scattering of light by the colloidal particles.BROWNIAN MOVEMENT is the movement of particles suspended ina liquid or gas caused by bumping with particles of the surrounding medium.The DISPHERSED PHASE is the sustance being distributed throught the mixture. The dispersal is the water ,while the disphersed phase is the mud. 111.125.109.98 (talk) 13:13, 28 May 2023 (UTC)
