Science 6:

Lesson 1 :

A combination of two or more substances that are not chemically combined is called a mixture.Mixture can be solid,liquid or gas.

A Solution is a Homogeneous mixture is a single phase mixture and cannot be identify or distunguished.

Example of a homogeneaous mixture:alloy,air and rubbing alcohol.

Water is the natural solvent

Solid is a solute

Lesson 2:

Factors that affect how a solute gets dissolved in a solvent:

1.Stirring or shaking -dissolved faster by solute,This happens beacause stirring caused the surface of each tiny particles of substances and other to be pulled away.

2.Crushing-the solid makes it dissolves faster.

3.Heat Energy-as motion of solute and solvent increase.

Lesson 3:

Miscble solution:is when two liquids do is form a new liquids.

Immiscble's solution:is when two liquids do not mix together instead form layers.

Miscble solutions is a Homogeneous mixture and it is uniform.

Immiscble solutions is a Heterogeneous mixture and it is non-uniform.

Lesson 4:

Solutions are Homogeneous mixture:

Solutions are combinations of two or more substances forming a homogeneous mixture.

Solutions are common at home.We use it in your everyday activities
