Rock candy science fair project

Where are the crystals? Soak the other piece of string in a cup of water for 5 minutes. Heat the solution until it just begins to boil, then remove it from the stove.

The string in this photo has been tied to a skewer and weighted down with a screw on the other end. Microwave water or heat it in a kettle until it starts boiling. This will ensure that you are not adding your hot sugar-water solution to a cold jar, which would result in a dramatic temperature change that might make small crystals form along the glass.

Encourage students to conduct background research on crystal formation and then construct a hypothesis. As the solution cools, crystals may form. Turn the heat down to low. After soaking, use your hand to squeeze the excess water from the string.

Sugar Crystallization

Do you ever think of salt? There are other forces in the solution that cause Rock candy science fair project to pull back apart but once in a while you get two molecules that hang on just long enough to attract another molecule and then another and another until a crystal structure starts to form.

Facts According to Exploratorium, crystals grow quicker in places where a crystal has already formed. After the three daywaiting period for prepping the strings is over, simply suspend the three cotton strings in their respective jars with the liquid sugar solution in the jars at room temperature for about one week.

Bring the water to a rolling boil on the stove. Once the project has been completed, allow students to record their results in written projects, display boards or oral reports.

Tie the small weight you chose to one end of the string and tie the other end to the pencil. Experimental Procedure Find out the saturation point of 1 cup of water. Mix with a wooden mixing spoon until all the sugar has dissolved. Day 2 Prepare the strings.

Carefully dip the string washer end first into the solution andlet it soak for a couple minutes. Here are just two types of crystals to whet your appetite, but know there are many many more out there waiting for you to discover them! Crystal Needles Crystal Needles are a great introduction to crystal growing.

In this case, sugar is our solid which is dissolved uniformly in a liquid, water. You can have some delicate, really cool crystals going within three hours time!

When the experiment is all set up, your rock candy growing jars should look like the one pictured here. Once cooled do not stir the sugar solution; jarring the solution breaks down the crystals and prevents larger crystals from forming.

Boil enough water to fill both jars. When the water is boiling, carefully pour it into the jars. Take your seeded string and tie one end to a screw, wooden bead, or other small object that can serve as a weight.

It is ready to be used to make rock candy. While you actually prepared your strings on the "Day 1" step above, for the purposes of the experiment, Day 1 in your data table will be the day you made your solution and began running the experiment. Using a liquid measuring cup, add 1 cup of water to a pot.

Lower the weighted end of the seeded string into one of the jars and rest the skewer across the mouth of the jar. Day 1 To start this science fair project, cut two pieces of yarn. Using pot holders, move the jars of sugar-water solution to a place where they can be left undisturbed for one week.

Cut a piece of cotton string about the size of the glass jar; tie a washer to one end and a pencil to the other end. Allow students to analyze the results and conclude whether or not their hypothesis was correct.

Rock Candy Science Project

After one week, you should see at least some sugar crystals. The units that are arranged can be molecules, atoms or ions which are all much too small to see with the naked eye, but whose arrangement gives crystals their characteristic structure.

By varying the amount of sugar, the solution may become saturated or supersaturated.

When Science is Sweet: Growing Rock Candy Crystals

Because salt also known as sodium chloride or halite crystals is a crystal, as is sugar and snow. Importance Teach students about the scientific method while conducting this class project. Place both jars in the same location.Jan 21,  · Complete this sugar crystal science fair project and learn all about it.

In this experiment, sugar and hot water are stirred together to form a varying the amount of sugar, the solution may become saturated or the solution cools, crystalsmay form/5().

Jun 02,  · In which Amanda teaches you about solvents, solutes, and recrystallisation via homemade rock candy. Give it a go, and post your results! Note: Not all.

Making Sugar Crystals

Pop Rock Balloons: Easy Science Experiment with Candy Today’s science experiment is super simple that should capture your kids attention like it did mine (you can see it on their faces in the pictures below). In this science fair project you will make a saturated solution of sugar and water in order to grow your own rock candy sugar crystals.

You will compare the rate of growth between rock candy that is left to nucleate on its own in the solution, and rock candy that starts off with some assistance.
