same amount of water
same type of salt
same amount of salt
same glass beaker
same amount of time on burner
different temperatures on burner
amount of time it takes to dissolves salt
salt- 1 teaspoon
set up beakers to all same amount of water
heat each beaker to desired heat to carry out experiment [ one beaker at room temperature, one beaker at 5 on burner, one beaker at 10 on burner ]
once you get each beaker to correct temperature after a minute of heating it on the burner take it off and add 1 teaspoon of salt, to each cup
turn the timer on and stir each one and observe when all the salt is dissolved and stop the timer and rcord the time.
repeat this step 3 times for each of the 3 beakers
would a different brand of salt dissolve at a different rate?
