Zaakirah's+Rock+Candy+Crystals

= ﻿Does changing the amount of seed crystal (sugar) affect how fast rock-candy crystals grow? =

By Zaakirah - upload a picture of yourself here = __Task 1: Answer these Questions__  =

__1. How do you make a saturated solution?__ __A saturated solution is if you add to much salt to the water it will not be able to absorb anymore salt, so it will fall and form clump.__ __2. Which holds more sugar: cold water or hot water? Hot water can hold more solid before it becomes a saturated solution.__

__3. How do crystals grow? Crystals grow through a process called nucleation.molecules are forced together in some way that they form structured chemical bonds.__

__4. What is nucleation Nucleation is when some components in a solution precipitate out and form nuclei that attract more precipitate. Nucleation is a physical reaction.__

__Task 2: List your independent, dependent and controlled variables:__
__1. Independent variable: Amount of sugar__

__2. Dependent variable: Size of rock candy__

__3. Controlled variables:__

1. The temperature 2. The jar size 3. The string 4. The liquid = __Task 3: What is the hypothesis for your experiment?__  = The longest string will grow faster.

= __Task 4: What equipment do you need for your experiment?__  = __1. granulated white sugar [ 3 cups ]__ __2.water__ __3.cup__ __4. Tablespoon measuring__ __5.small plate__ __6.wax paper__ __7.screws,wooden beads,or small nontoxic objects to use as weights [2]__ __8.wooden screws,popsicle sticks, or pencils__ __9.tape__ __10. pot__ __11. stove__ __12. measuring cup [ for liquid ingredients__ __13.__ __14.__ =  __Task 5: List all steps in the method of your experiment (try and include a diagram or video that helps explain):__  =

__**Task 6: Observation and discussion**__

Note down what you noticed as you did each experiment. Try and include an image or a video or photos of your experiment.
