```CORE CONCEPTS THAT MAKE UP THE TOPIC YOU CHOSE
1) What do you intend the
this topic?
2) Why is it important for
students to know this?
3) What else do you know
you do not intend
students to know yet)?
4) What are the
difficulties/limitations
associated with
teaching this topic?
Core Concept 1
Students are
recalled
homogenous
mixture, solvent,
solute and solubility
etc..notions which
were showed at
primary school.
Students frequently
face with this topic
in their everyday
life
So knowing this
topic can make their
life easier and
provide them to
understand their
environment.

Core Concept 2
Students learn the

they can explain

Concept Concept 3
Students learn the
percent solubility
notion and know
that solubility is
identity of matter or
distinguishing
property of matter.
This topic is one of
the basic and
important topics in
chemistry.So, if
student aims to
continue his/her
career in this are a

he/she should learn
this topic properly

Core Concept 4
Students can

of a solution(such
as sugar water

use to teach this topic?
Explain the reasons for
using these methods or
strategies.
