What is a hypothesis for rock candy experiment?
My hypothesis is that crystals will grow faster in hot temperature water rather than in room temperature or cold temperature water. The purpose of this experiment was to determine which temperature (hot, cold or room temperature) affects crystal growth rate the most.
What is the purpose of the rock candy experiment?
The purpose of this experiment was to determine which temperature (hot, cold or room temperature) affects crystal growth rate the most.
What is the independent variable in making rock candy?
Independent variable (also known as manipulated variable) is the temperature. Dependent variable (also known as responding variable) is the amount of crystals formed in a certain period of time. Constants are the amount of water, the amount of sugar, the size of the jar in each crystallization trial.
Is rock candy a chemical reaction?
Chemical Reactions- Two chemical reactions take place, first the sugar dissolves in the boiling water and then crystals form. Chemical Equation- The chemical equation for rock candy is C12H22O11(aq)–> C12H22O11(s).
What is hypothesis example?
Examples of Hypothesis:
- If I replace the battery in my car, then my car will get better gas mileage.
- If I eat more vegetables, then I will lose weight faster.
- If I add fertilizer to my garden, then my plants will grow faster.
- If I brush my teeth every day, then I will not develop cavities.
Is rock candy bad for you?
Some people believe rock sugar is healthier than white granulated sugar. However, there is no scientific evidence to support that rock sugar has distinct health benefits over granulated sugar. Moreover, rock sugar is often made from refined white sugar, making its chemical composition identical.
Why didn’t my sugar crystals grow?
Why didn’t my rock candy grow crystals? If crystals don’t grow it is almost always due to lack of sugar. If after 24 hours you don’t see any crystal growth, pour the syrup back into the pan and add more sugar. Roll the sticky skewers in sugar and add once more to the jar after the syrup has cooled down.
Do sugar crystals grow faster in tap water or distilled water?
If you input “Do sugar crystals grow faster in tap or distilled water?” to answers.com, you’ll get the following response: Distilled because tap water has iron, fluoride, and chlorine in it! Carbonated water has too much or sparkling and gas in the water that it isn’t pure enough to grow fast enough , or the vitamins.
Can you use yarn for rock candy?
YARN WORKS BEST FOR CRYSTAL FORMATION Yarn works better than wooden skewers because of the friction of yarn.
What sugar makes the best rock candy?
Here’s what you need:
- Granulated Sugar (for 5 sticks of candy, you’ll need 10 cups)
- Food coloring (if you want to add color to your candy)
- Mason jars or other receptacles to hold sugar solution.
- Skewers or sticks to make rock candy on.
What is a good hypothesis example?
Here’s an example of a hypothesis: If you increase the duration of light, (then) corn plants will grow more each day. The hypothesis establishes two variables, length of light exposure, and the rate of plant growth. An experiment could be designed to test whether the rate of growth depends on the duration of light.
What are the variables in making Rock Candy?
Variables For Making Rock Candy 1 Dependent variable: This is generally identified by the purpose of the exploratory experiment.For example: Purpose:… 2 Independent variable: You now want to identify all the possible variables that might affect the development of sugar… More
Where does the sugar in Rock Candy come from?
Rock candy is actually a collection of large sugar crystals that are “grown” from a sugar-water solution. Sugar, like many other materials, can come in many different physical states.
What kind of science can you do with Rock Candy?
It can be a most delicious subject, too. When you make this treat, you’ll be jumping “string-first” into some serious chemistry that’s hiding as candy. You’ll discover and use principles like solutes, solvents, viscosity, sedimentation, solutions, and supersaturated solutions.
How to do a taste test for Rock Candy?
Pictures are a good idea! When you’re ready for the big reveal, lift the pencil and pull the string loaded with crystals out of the jar. Lay them on some wax paper and look closely at what grew on the string. Of course, a taste test will have to be a part of your analysis.
