 Activity(ies) in steps
-After greeting ,the students set in groups.
- task (1): …………………….(15 min)
1- each group make a mixture from sugar and water
2- the students answer the following questions in task one to know the following terms(solution –
solvent – solute- solubility)
Activity -1- one group will do this activity
- to prove that quantity of solvent &solute affect the solubility .
1- get equal quantity of sugar
2- bring the two beakers one have 300ml of water and the other contain 50ml water.
3- stir each beaker separately and record the time of solubility .
4- try to dissolve different amount of sugar in each beaker that have the same
amount of water.
-students answer task two…………….(10min)
Activity -2- one group will do this activity
- To prove that temperature affects the solubility process
1-put two equal amount of sugar in two beakers
2- put two equal amount of water in each beaker one is tape water and the other is
hot water
-students answer task three………………(10 min)
Activity -3- one group will do this activity
- To prove that stirring affects the solubility process
1-put two equal amount of sugar in each beaker contain the same amount of
water .
2-stir one of the beakers with glass rod and leave the other .and record the time of
solubility.
-students answer Task four …………………..(5min)
Activity-4- one group do this activity
- To prove that kind of solute affect the solubility
1-put sodium carbonate with water . and put salt in another beaker with
water.
2- heat both of them gently with stirring. And record the solubility time.
-students answer task (5)………………….(5min)
- each group will say the result and the conclusion they know.
Solution:
It is the homogeneous mixture that is formed of solvent and solute.
Solvent: it is the substance in which solute disperses or dissolves
Water is called a common solvent B. more substances dissolve in it
Solute:
It is the substance which dissolves in a solvent
Solubility:
It is the process by which a solute dissolve sin a solvent.
Solute +Solvent

Worksheet
Task (one): make a mixture from sugar and water.
the students answer the following questions to know the following terms(solution –
solvent – solute- solubility)
1- On dissolving sugar in water ,is this homogenous Or heterogeneous mixture?
……………………………………………………………………………
2- What do you need to make a solution? 1- Something to dissolve - a solid.
2-A liquid to dissolve the solid - water.
S0 The mixture of sugar and water called ………………………………
3- In sugary solution: The solvent (liquid material) is ……………… but the
solute(solid material)is ……………………
4- Can we make solution with sand ? why? …………………………………………….
5- Dissolving the sugar in water so sugar is (soluble –insoluble) in water this process
called ……………
Important Words
Solvent - Any liquid used to make a solution.
Solute - Any substance that dissolves in a liquid (solvent)
Solution - This is what you make when a solvent and solute get together.
solute + solvent = solution
Task two: Activity (1)
- to prove that quantity of solvent &solute affect the solubility .
1- get equal quantity of sugar
2- bring the two beakers one have 300ml of water and the other contain 50ml water.
3- stir each beaker separately and record the time of solubility .
4- try to dissolve different amount of sugar in each beaker that have the same amount of water.
Answer the questions if you do the activity
1- The beaker that dissolve the solute fast is………. So the solubility time (short –
long).
- After doing step 4 ; 1-the beaker that dissolve sugar fast is …………..
-Conclusion:
If the solute increase the solubility time ……….. but If we increase the solvent, the
solubility time ……………………..
Task three; Activity (2)
- To prove that temperature affects the solubility process
1-put two equal amount of sugar in two beakers
2-put two equal amount of water in each beaker one is tape water and the other is hot
water.
Answer the following:
1- The beaker that dissolve the sugar fast is……………..
2- Conclusion : The solubility time …………………..if the temperature increase.
Task four: Activity (3)
- To prove that stirring affects the solubility process
1-put two equal amount of sugar in each beaker contain the same amount of water .
2-stir one of the beakers with glass rod and leave the other .and record the time of
solubility.
Answer the following:
1- The beaker that dissolve fast with (stirring – without stirring) choose.
2- Conclusion: The stirring ……………..the solubility process increase.
Task Five: Activity (4)
- To prove that kind of solute affect the solubility
1-put sodium carbonate with water . and put salt in another beaker with water.
2- heat both of them gently with stirring. And record the solubility time.
Answer the following;
1- Which solute dissolve fast ? …………………………………………..
2- The solubility time ……….if the solute dissolve fast
Conclusion ; \
The kind of the solute affect the …………………………
