Cornstarch Essays

If I add any other substance other than water the cornstarch will it still change into a solid-liquid matter? Colloids have the capability to change from a liquid to a solid by movement or even touch. Colloids often harden when they are being moved by if it’s in your hand it will turn into a liquid matter. According to("Science Activity: Is This Stuff a Liquid Or a Solid? | Exploratorium") l the main idea about this subject is to show how to make your own ooze. Isaac Newton identified the properties

starch molecules diffuse across a plastic “membrane?” Hypothesis: If the iodine and cornstarch are placed in the same beaker, then the answer can be determined. Materials: Plastic sandwich bag Zip-lock bag Tincture of iodine Cornstarch (2) 500 mL beakers Eyedropper Graduated cylinder Procedure: Fill one beaker with 250 ml of water Add 60 drops of iodine Fill a second beaker with 250 mL of water Add 3 teaspoons of cornstarch and mix well Pour ½ of the starch and water solution into the plastic sandwich

Without borax: The second method is the cornstarch goo. The cornstarch goo can

clumps of flour in it. It will also be thicker. Water - Cornstarch Heterogeneous Mixture It would be thick and more cloudy. Water - Vinegar Homogeneous Mixture The substance would be same but it would have a higher smell. Vinegar - Baking Soda Homogeneous Mixture It will create a

'll need are; a spoon, a large bowl, and a measuring cup. Next, you need to gather all of your ingredients. There 's two main ingredients and one that is optional. You 'll need cornstarch, water, and the optional ingredient is food coloring. After you 've got everything you need, measure out about 1 cup of cornstarch and pour it into your bowl. Then,

From here on the words that would help you along the way of the lab for your research is mixture, homogeneous mixture, and last but least heterogeneous mixture. The hypothesis or guess on what would happen when the water is mixed with the cornstarch, is the cornstarch and water will mix and form a new liquid/solid. However, the Investigating Mixtures lab objective was to observe that not all liquids behave the same way when mixed with other liquids. Moreover the hypothesis of this experiment was that

powders and 3 liquids. The powders were baking powder, baking soda, cornstarch. The liquids were water, iodine solution, and acetic acid. Of these experiments, 5 were chemical reactions and 4 were only physical changes. Of the powders, baking powder was the most reactive because it chemically reacted with all 3 liquids. Baking soda and cornstarch both reacted with 1 out of the 3 liquids. Baking soda reacted with acetic acid. Cornstarch reacted with iodine solution. Of the liquids, iodine solution and

Based on result driven from various trials done, more of polyvinyl acetate and cornstarch are required to establish stable spherical shape ball. Less of polyvinyl alcohol and borate should be used since no evident loss of bounce efficiency was seen when a decreased amount of polyvinyl alcohol was used. Same was observed with borate since

white, lumpy, and possessed no lust, Powder B appeared to be white, soft, and lumpy, Powder C appeared to look smooth, white, and soft, and Powder D appeared to be lumpy, solid, and whitish-yellow. The materials that were utilized in this lab were cornstarch, baking powder, baking soda, powdered sugar, spot plate, scoopula, dropper, water, vinegar, iodine, toothpicks, and paper towels. The physical property that was observed was solubility, the ability of something to be dissolved, and the chemical

Analysis Conclusion Based of the data collected from the experiments, cornstarch was identified as the unknown powder in the black bag. Cornstarch shares similar chemical properties compared to the unknown powder. They both have a pH of 7, contain starch, but not carbonate, and react with the flame to create a temporary bright orange. Even so, powdered sugar also has the same chemical properties. However, when the powders were viewed in the Scanning Electron Microscope, the powdered sugar

of two or more substances. A homogeneous mixture is a uniform instructure or composition throughout the substance unlike a heterogeneous mixture which consists of dis familiar parts of elements. The lab’s hypothesis is that when you play with the cornstarch and water mixture it’s a solid, but when it’s left alone it liquifies. However, the Investigating mixtures lab has an objective to observe that not all liquids behave the same way when mixed with other liquids and the hypothesis is that the oil

In this lab, we tested 8 known ingredients to find what ingredients was in our unknown A and unknown B medications. We first tested the water solubility of our knowns and unknowns. We found that of the knowns, cornstarch and acetaminophen were the only ones not water soluble. The unknowns were also not water soluble. Th next test was the pH test. The unknowns were all basic except for the acetylsalicylic acid which was an acid and pseudoephedrine hydrochloride which was a neutral pH when tested

same). In addition, my hypothesis for this lab is the cornstarch and water will make a liquid-solid substance. The Investigating Mixtures Lab objective is to observe that not all liquids behave the same way when mixed with other liquids. Also, my hypothesis for this lab is the vegetable oil will not mix with the water. Conclusion/Analysis:

Acetylsalicylic Acid (Aspirin), Calcium Chloride (deicer), Ascorbic Acid, Cornstarch, Epsom Salt, all through six tests- physical appearance, hardness, conductivity as a solid, solubility in water, conductivity as a liquid or solution, and melting point. Hypotheses If we test physical appearance then all compounds will be white and somewhat transparent. Sugar and salt will be composed of small grains. Deicer, Cornstarch, Vitamin C, and Aspirin will be all be in a powder like form. Paraffin Wax

The childhood snack that will be analyzed is Fruit Gushers. The following are the five ingredients in this snack: Red 40 (Allura Red), partially hydrogenated cottonseed oil, carrageenan, corn syrup, and monoglyceride. Red 40 is an azo dye that contains an N=N grouping which is called an azo group. This dye dissolves in water because it’s a salt and contains sulfonic acid. This sulfuric acid molecule bonded to a carbon and its acidity is neutralized in order to give it its form. The side effects

to make it easier to open up the seal. We tied up one end of the dialysis bag with a piece of string and filled the bag with 13 mL of dissolved cornstarch in water. Then we tied up the other end of the dialysis bag with a piece of string and placed the bag into potassium iodide and water solution. We waited and observed the change of color in the cornstarch mixture as it sat in the

hand. I chose yellow and red. I thought it would make orange, but it did not. I figured this was because the elmer's glue was white and it turned the glue salmon. Then we put the same measurement of cornstarch in the beakers and stirred with a spoon.

Hypothesis The hypothesis of this lab was: if you change the temperature of oobleck, then its density will change as well as its state of being. Procedure The lab started out with the creation oobleck. To create oobleck, you will use twenty grams of cornstarch to twenty grams of water (measure with a electric balance), vigorously stirred in a beaker. Once the oobleck is created, measure its total mass, as this will be the control. To do this, subtract the beakers mass before and after the oobleck was

the juice would spend in the microwave, for instance one condition had 40 seconds, another had 80 seconds in the microwave, 160 seconds and the control with no exposure to the microwave. In order to carry out the experiment cornstarch was added, about .1 gram, the cornstarch served as an inhibitor making the ascorbic acid show when the IKI was added. The amount drops added was converted into milliliters, and by the data it can be determined that the hypothesis was approved.

the properties of similar-looking materials can be used to tell them apart. Experimental First a well plate was obtained, and it was cleaned and dried as necessary. A spatula was used to place a small amount of cornstarch in each of three wells, and the physical properties of the cornstarch was observed and recorded. A clean spatula was then used to place a small amount of baking soda in each of three new wells, and the physical properties of the baking soda was observed and recorded. Next, a clean
