Hypothesis: If forming rock crystals takes a specific composition of a solution, then how does a different solution of the sugar water and water affect the way the crystals form?
Topic: Rock candy formation
IV: I will experiment with creating different compositions of the ingredients needed to make rock candy.
DV: I will measure the weight of the crystal in grams, and visually the size of the crystals.
For my experiment, using different sugar solutions, such as sugar water that is 25% sugar, 50% sugar, etc. and I will remove the crystals after a set time and weigh them to measure amount of crystals formed. I will hold the room temperature constant and the time for the crystals to form.
Materials:
-A pot to boil water in
-Water and sugar
-Food dye

Topic: Newton’s Cradle
IV: I will change the materials in between the balls and the density of each ball that transfers energy to the ball on the end.
DV: I will measure the angle of the ball on the end at its maximum height.
For my experiment, I will create Newton’s Cradle and change the density of each ball involved, and I will also place different materials between the balls. I will always keep the ball on the end of the chain the same density and mass. Each time I change the materials in-between the balls and the density of each ball, I will take a slow motion video and take a picture of the final ball at its maximum during the video. I will then print out the picture and measure the angle with a protractor.
Materials:
-Balls of different mass and density
-Protractor
-Camera
-Newton’s
Procedure: Measure the volume, mass, length and temperature of a variety of items. Create dilution of sugar water.
of sugar to 25ml of water and dissolve it. When we have the water at
Rock candy is a simple scientific experiment made at home from sugar and water. Rock candy can be made up of different types of sugar. I used pure cane granulated sugar. Rock candy is formed when sugar is dissolved in boiling water and is cooled and placed in a glass jar with the wooden skewer. When the water evaporates the sugar crystal will start to grow overtime. The water and sugar is a saturated solution, meaning that water could only hold sugar if both were very hot. By cooling the water, the sugar comes out of the solution and forms crystals on the skewer and around the glass. The hypothesis for my experiment was that the more sugar you use the more crystals will form. My question is if you add more sugar, will more crystals?
21) After all of the solid dissolves, move the flask from the hot plate and allow it cool to room temperature. After a while, crystals should appear in the flask.
1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around.
Crystallization was induced in the solution by scratching the inside of the beaker with a glass stir rod. 2. Next, an ice bath was made by partially filling a 400 mL beaker with ice and covering the ice with water. 3. The beaker containing the solution was then placed in the ice bath for approximately 15 minutes.
Use stopwatch to record the time it took when the sugar is completely dissolved. Stop the experiment at 1 minute and 30 seconds if the sugar does not dissolve.
Have you ever considered growing rock candy crystals from scratch? Well after doing research, I found a way on just how to do this. I will share the procedure I used as well as the results that I found. It was a time consuming process, but I had fun doing the experiment. The question was asked, "How does the sugar coated string versus the non-sugar coated string affect the growth of a rock candy crystal"? I formed my own hypothesis out of this question and it was that the sugar coated string will have more crystals because there was sugar on the string.
Looking back at the first test trial of making the rock candy, there is plenty of room for improvement. To start off I would change the type of jar we are using into a taller, more slender one. This way we are able to see the crystals form better onto the wooden stick, as it was hard to see what was happening when we observed them. After reading the article about the crystals growing in the caves of Mexico, I believe that we can improve the experiment through the temperature. In the article it talks about how the crystals grew into giant sizes due to the temperature being very hot and consistent. So, if we were to put the crystal experiment into something else, it would be a container that will insulate the heat, like a thermos. The thermos
In a variation of the project you could try different amounts of copper sulfate crystals, probate mixture, or luminol mixture on the same amount of water. Also you can change the amount of water and use the same amount of copper sulfate crystals, probate mixture, or luminol mixture. To see the effect on the duration of the luminols light you can try stirring for different amounts of time or at different
The songs “Friends” and “Candy Store Rock” were great pieces of work by Led Zeppelin. “Friends” starts off with some chatter in the background. After that comes the acoustic guitar with some bongo drums, indicating that this song was inspired by the Africans. This folk styled music involves a lot of string, which carry a repeated, slow melody. Near the end of the song, the tempo picks up. “Candy Store Rock” is a rockabilly song, influenced by Elvis Presley. It has a fast tempo, featuring some high pitched, distorted guitar sounds. The vocals at the end have a lot of reverb. What I find interesting about these two songs is that they designate a different style of music, especially when they are both written by the same band. This shows that
Continue dropping the water until you get to 200 drops, stopping every 10 drops to stir with a fork. Repeat steps 3-7, two times for a total of 3 trials. Repeat steps 3-8, using the sugar and then sand. The objective of the experiment was to determine whether the independent variables and water are either a colloidal solution, true solution, or a suspension.
My hypothesis was that if the heavy bowling ball is bowled then it will knock down the most pins because it will have more kinetic energy. In this experiment I went to our local bowling alley and tested three different bowling ball weights (2.72 kg, 4.54 kg and 6.35 kg) in order to determine if the heaviest ball would in fact knock down more pins.
Rock Candy (also called rock sugar) is a type of confection composed of relatively large sugar crystals. This candy is formed by allowing a supersaturated solution of sugar and water to crystallize onto a surface suitable for crystal nucleation, such as a string, stick, or plain granulated sugar. Heating the water before adding the sugar allows more sugar to dissolve thus producing larger crystals. Crystals form after 6–7 days. Food coloring may be added to the mixture to produce colored candy.
Crystals were collected in a Buchner funnel, washed with alcohol, then ether, then transferred into a sample tube for storage.
