RESULTS AND OBSERVATIONS: Method Sieving or filtering Settling overnight Evaporation Boiling Result - Could you recover the sugar from the solution? 1. Which methods worked to recover the sugar from the solution? 2. What was left at the bottom after completing these methods? 3. Why do you think this happens? 144 Matter and Materials
4. Which method do you think works best and why? CONCLUSION: What can you conclude from this investigation? Now that we have looked at how to separate a solute from a solution, have you ever wondered just how much sugar you could dissolve in the water? Do you drink tea for example, and put sugar in? How many teaspoons of sugar do you think you can dissolve in a cup of tea? In the next section we will explore this idea. 3.3 Saturated solutions Suppose we were to make a cup of tea and we put in 3teaspoons of sugar. Mmm... lovely sweet, warm tea! QUESTIONS Now imagine you add 3more teaspoons of sugar to the tea. How many teaspoons of sugar did we add? When the particles of asolute spread throughout the particles of a solvent, we say the solute dissolves in the solvent to make a solution. Chapter 3.

CONCLUSION:<br />
What can you conclude from this investigation?<br />
Now that we have looked at how to separate a solute from a<br />
solution, have you ever wondered just how much sugar you could<br />
dissolve in the water? Do you drink tea for example, <strong>and</strong> put sugar<br />
in? How many teaspoons of sugar do you think you can dissolve in<br />
a cup of tea? In the next section we will explore this idea.<br />
3.3 Saturated solutions<br />
Suppose we were to make a cup of tea <strong>and</strong> we put in 3teaspoons<br />
of sugar. Mmm... lovely sweet, warm tea!<br />
QUESTIONS<br />
Now imagine you add 3more teaspoons of sugar to the tea.<br />
How many teaspoons of sugar did we add?<br />
When the particles of asolute spread throughout the particles of a<br />
solvent, we say the solute dissolves in the solvent to make a<br />
solution.<br />
