What is the effect of evaporation on sugar crystal growth? | By: HYKEYLA dunn | | | Table of contents: Introduction Purpose and Hypothesis Materials and Experiment Results/Data Discussion Conclusion What are crystals and how do they form Bibliography acknoledgements Introduction Rock candy is a collection of large crystals grown from sugar water solution. Other materials like sugar comes in many physical states. It can be either amorphous, without shape, or crystalline which is a highly structure and shape. Purpose and Hypothesis The pupose of this project is to investigate how the presence of seed crystals changes the growth rate of rock candy. My hypothesis is that seeding the string will affect the growth rate of sugar crystals. Materials 1 quart saucepan 1 glass container with a lid 2 cups of regular table sugar 3/4 measuring cup a few drops of food coloring 1/4 teaspoon of flavoring (such as peppermint, lemon, cherry or strawberry extract)optional 1 thin wooden stick or string ruler tape or plastic wrap Experimental procedure 1.measure 3/4 of water and pour it in sauce pan. Heat on medium high until it comes to a boil. 2.pour 2 cups of sugar in sauce pan and stir.the solution should look cloudy at first then i will become clear .then keep stirring for 2 minutes 3.After the sugar is dissolved pour the solution into the jar. 4.seed one stick by covering it in sugar.set the non seeded stick aside 5.insert the seeded stick into the center of the lid and cover all holes. 6complete steps 1-4 and insert non seeded stick. For best results let it sit for a week or more (seeded) Observations Day 1(sugar solution made) During the first 2 hours tiny crystals started to form Day 2 The sugar is starting to form Day 3 The crystals are a little bigger the day before Day 4 On the fourth day there is an increase of the amount of
