Solution rate inquiry lab:

Question

For class, we have to design our own lab given the info from class.
My question is: Does the INTRO, HYPOTHESIS, PROCEDURE, & DATA CHART all make sense? I feel like I'm missing something or the hypothesis could be fixed or all the above factors BOLDED could be changed. PLEASE HELP. LAB 1/18/2017 .....

SOLUTION RATE INQUIRY LAB
INTRO: (technically we didn't do the lab yet and the 1st sentence seems as if we did... rewording?)
When performing a solubility experiment, using a stirring rod to move the solvent around the solute causes portions of the solvent to come into contact with the liquid, which in turn makes it dissolve faster. In this experiment we’ll be testing how long it takes for rock salt to dissolve in different temperatures of water by stirring the two substances.

Materials:
•3 test tubes
•Stirring rod
•Distilled water
•NaCl (rock salt)
•Stopwatch
•Balance
•Bunsen Burner
•Wire Gauze
•Striker
•Test tube clamp

Hypothesis:

If you use a stirring rod to mix salt in different temperatures of distilled water, then the rate of solubility will increase.

Procedure: (3 trials testing the temperature of water in room temperature water, cold water, and hot water and how long it takes for the salt to be dissolved)

Do these steps or procedure make sense?
Part 1/Trial 1:

1.Measure 20 mL of room temperature distilled water with a graduated cylinder
2.Then pour the 20 mL of distilled water into a test tube.
3.Next measure out 1 gram of salt
4.Get out the stirring rod and stopwatch
5.Carefully pour 1 gram of salt into the room temperature distilled water
6.Start your stopwatch and begin stirring.
7.Keep track of time while stirring!
8.When the salt is completely dissolved, record the stop time into your data chart.

Part 2/Trial 2:
1.Measure 20 mL of room temperature distilled water with a graduated cylinder
2.Then pour the 20 mL of distilled water into a test tube
3.Next measure out 1 gram of salt.
4.Get out the stirring rod and stopwatch.
5.Carefully pour 1 gram of salt into the cold distilled water
6.Start your stopwatch and begin stirring.
7.Keep track of time while stirring!
8.When the salt is completely dissolved, record the stop time into your data chart.

Part 3:
(BC in this trial, heated water is usen, I was thinking these steps but not sure where to include them or if it's right or makes sense: 1. Use the striker to ingite the Bunsen burner.
2. Then use the test tube clamp to clamp the test tube.
3. Hold the test tube clamp at a 45° angle at the top of the inner blue cone.)

4.Get out the stirring rod and stopwatch.
5.Carefully pour 1 gram of salt into the cold distilled water

7.Keep track of time while stirring!
8.When the salt is completely dissolved, record the stop time into your data chart.

Here is the chart (does this make sense):
Left Column: Column 1(temp)| Column 2 (time)
Row 1: test tube/ trial 1
Row 2: test tube/ trial 2
Row 3: test tube/ trial 3
R1C1= room temp
R2C1=Cold temp
R3C1= heated temp
______________________
R1C2, R2C2, R3C2=time (haven't done experiment yet!!!)

Sorry, I tried to condence it. Hopefully someone can help me clarify! Would really appreciate it!
