What Kind Of Substances Make Gel The Fastest
For the scientist’s experiment the scientist will be experimenting with additives and gel. We will be adding different substances such as table salt, citric acid, and sugar. The scientist’s problem statement is “What kind of substances make gel the strongest?” The independent variable will be the different additives (Table salt, citric acid, and sugar) which will be added using tablespoons. The dependent variable is the strength of the gel which will be measured using a scale of 10. The constant variable is the type of gel used and the amount of substance added to the gel which will be 2 tablespoons.
The scientist’s hypothesis will be, “if we add citric acid to gel, it will become strong enough to hold multiple pennies because the substances
will be able to chemically combine with the gel and give it strength.” For this experiment, the scientists will start the experiment by adding two teaspoons of sugar, salt, and citric acid to empty ice cube compartments. After that, the scientists will make the gelatin. Then, the scientists will pour gel into each ice cube compartment, put foil over them and let it set overnight. While this is happening, a toothpick will be poked through a paper cup. When the gel sets, the toothpick on the bottom of the paper cup will be poked through the foil. Pennies will be added to the cup and when the cup starts to descend, the scientists will stop. When the cup stops moving, the scientists will continue adding pennies until the bottom of the cup reaches the foil. The pennies will then be taken out and weighed on a kitchen scale. The information will be taken down and analyzed.
Gel is often used for experiments on diffusion. Diffusion is the spreading of something more widely. Young kids learn about this topics by putting food coloring inside the gelatin and observing how much the food coloring spreads out every hour. Various journal entries also speak of gel in other ways. Statements similar to the scientist’s were told in a journal entry about gelatin’s strength. The entry talks about different polymer concentrations being used on the gel. Polymer is a large molecule or macromolecule that is composed of many repeated subunits. The scientists tested the gel’s strength using storage modulus. the storage modulus measures stored energy. The storage modulus was used to characterize the gel’s strength. Going off of that, a new type of gel was discovered in 2001. The gel was obtained by “chemically cross-linking polyrotaxane molecules in solution”. The tension of the threaded polymer chains was increased. Scientists also discovered that gelatin is can be used as a gene carrier. The article states, “A DNA and gelatin nanoparticle coacervate containing chloroquine and calcium, and with the cell ligand transferrin covalently bound to the gelatin, has been developed as a gene delivery vehicle”(Leong, 1999). This means that the substance is able to carry genes, or as the article states it is a “gene delivery vehicle”. An interesting article stated that gelatin can actually help strengthen your fingernails. Scientists ran an experiment and had a group of fifty people ingest gelatin daily for three months to see how their fingernails reacted. 43 of the 50 participants reported that their nails has shown improvement. A woman and her husband did a similar experiment and saw improvement in their fingernails. These journal entries and articles will help the scientists answer the question, “What kind of substances make gel the strongest?”.
