Glycerin is an organic compound of vegetable fat. It is colorless and has no odor (odorless). This experiment was to test to see the final result testing the effect of glycerin on plastics.

Get the original essay This experimental hypothesis was: A biodegradable plastic can be choked depending on the amount of glycerin added, as the plastic is made from polymers and we can eliminate some of these polymers by eating the chemical in a. According to research, glycerin is a very soft liquid. It can be used as a moisturizer, I mean it can be used to prevent or treat skin like rough, dry skin, etc. The reason glycerin makes plastic smoother is because it has a chain between polymers that gives it a soft surface and soft glow. (Agriculture at the work of bioplastic). Glycerin has a great function in palpating the spaces between polymer chains in bioplastics, thus making the plastic more extensible (Odec). Cornstarch 10 g Water 50 ml Vinegar 5 ml Glycerin 5 ml Food coloring (optional) Beaker Stirrer Aluminum foil Lighter Bunsen lighter Independent variable: In this experiment, the independent variable is glycerin, because the more glycerin added, the more the texture of the plastic would be stuffy and this is something that could be changed. Dependent Variable: In this experiment, the dependent variable is the end result, that is, the biodegradable plastic having a smooth texture, because the aim was to see the effect that glycerin would have on the plastic and which can be explained and observed once the experiment is over. the experiment was c, which resulted in a smooth blue plastic. Pour 50 ml of water into 10 ml of cornstarch and glass rod together while mixing. Add 5ml of glycerin and make sure to add 5ml of vinegar then mix. Then add 3 drops of coloring to the mixture. Take the Bunsen burner, turn it on and gently place the baker over the Bunsen burner to warm the mixture and stir the mixture while heating. After that, take the baker and remove the mixture with a spoon. by placing it on parchment paper. Now set it aside and leave it for several days. Are the results the same for each group? No, the result was not the same for each group but very close. In other groups, their plastic texture was less and more subdued. The reason is that each group that participated in the experiment did not follow the procedure in exactly the same way. They may have measured the amount of substances that should be mixed, but not exactly the same amount. Since it's different, maybe other groups add less glycerin. ·What variable could affect plastic? The variable that the experiment has in temperature. During the experiment by hitting the mixture of substances, as the temperature increased, the substances began to boil, bubbles increasing as they rose and. During the experiment, the mixture should be watched as it is heated. Otherwise, it would have taken shape to become more solid. According to (Sciencelearn), the reason is that the particles are less densely packed than in the liquid state. Conclusion: The Goal The goal of this experiment was to determine if the effect glycerin would have on plastic was exceptional plastic. This has been proven by observations. it was difficult to determine whether the paint layer was evenly distributed across the surface of the plastic. Glycerin could be an eco-friendly substance..
