why does honey crystallize science fair project

5 small, identical food jars with lids
Honey (If possible, get natural honey that s from a local farm. Some honey is mixed with other substances, and this could change the results of your experiment) Add a small amount of cold water to each container. Container #1 gets one teaspoon of water, container #2 gets 2 teaspoons, container #3 has 3 teaspoons, and container #4 has 4 teaspoons. The fifth container will have only honey. Add 1 tablespoon of honey to each of the containers. This is the tricky part, since honey doesn t like to flow easily off a spoon! Oil your spoon using the cotton ball by dipping the ball in the oil and spreading it lightly over the spoon. Next, fill the spoon with honey. Finally, push the honey off the spoon into the container. Use the Popsicle stick if you need to scrape it off the spoon so that you don t feel tempted to eat the experiment! Use the popsicle stick to gently mix the honey and the water together in each jar. Create a hypothesis, your best guess about what is going to happen. When you put your containers in the freezer, which one do you think will crystallize the fastest?

Why? Create a chart to track your findings. The chart will have five rows. On the left side of each row, place the jar numbers. Begin with jar 1 at the top and go down to jar 5 at the bottom. On the top of the chart, place times. The first time is 2 minutes, the second is 4 minutes, and so on. You will place an X under the time when you first see crystals forming. On the side of the chart, create an area for notes. This is where you will note the temperature at which each jar of honey started to crystallize. Put all of the jars into the freezer, and set a timer. After 2 minutes, look at the jars and check them for signs of crystallization. The honey may look rough or cloudy. Watch the jars but try not to handle them, since the heat from your hands could change the way the honey crystallizes. Continue to look at the jars every 2 minutes. If you see crystals forming, place the thermometer into the honey and record the temperature on your chart.

The honey without water will crystallize first. Why? When we think of crystals, we usually think of precious jewels but the truth is that many things crystallize. In fact, salt and sugar are both crystals. When you stir salt into water, it looks like it disappears but in reality, it s still there; it s just dissolved into the water. Let that water dry out, and salt crystals will be left behind. Like salty water, honey is a solution, which means that bits of sugar are spread throughout a liquid. When honey crystallizes, the honey molecules spread throughout the liquid come together to form solid crystals, and the more dissolved bits of a solute there are in a solution, the faster that solution will crystallize as it cools down. Mixing more water into a solution makes it crystallize more slowly. Heat also changes how quickly crystals form. Every solution has a temperature at which the solid is spread throughout the liquid. For honey, this is around room temperature. Honey is made up of a lot more than just sugar and water!

Raw honey contains many different nutrients and may even contain bits of pollen. Some honey comes the nectar bees gather from specific flowers, such as clover, while other honey is a mixture of different nectar sources. Try this experiment again, using honey from the nectar of different flowers. Do the flowers make a difference when it comes to honey crystallization? Why? Do some flowers have sweeter nectar than others? To set up an experiment which visually demonstrates sugar crystallization. From this, we want to determine a material from which to start the crystallization in order to create the "best" crystals. For this experiment, it is recommended (not necessarily required) to have a basic understanding of high-school chemistry. To perform a sugar crystallization, most experiments involve saturating water with sugar. See. For more background knowledge on sugar crystallization, click. On which material do you think would be best to begin growth of crystals? You might want to start off with nylon or cotton. Large, clean glass jar Pour water and sugar into a pan.

Caution with boiling water. Adult supervision is required for boiling. Check out our. Pour sugar-water solution into the glass jar. Tie the string and let it dangle from the center of the pencil so that it almost touches the bottom of the jar. Keep stored and check daily. Make sure that it remains undisturbed. Repeat this process for different type strings. Which string seemed to hold the crystals best? Why do you think that is the case? Be sure to keep in mind that the string may not have a sole effect on the crystals forming on it. Do you think you can find other materials which would serve better than the ones used in your initial experiments? What other factors do you think affected the crystallization (room temperature, water impurities, etc. )? What other factors do you think affect the growth of crystals? Do you think there is a way to speed up the crystallization process? Try looking into to improve the results of the experiment. What other could you use to make crystals?
