ScienceInvestigatory Project Year and Section: III ² Our Lady of Lourdes Submitted by: Renier Joseph Dela Rosa Alison Caliwan Kim Paolo Aquino John Joshua Furbeyre Julius Castillo Submitted to: Ms. Pastor a) Problem Could we make colors from plants? b) Title U sing Natural Dyes from plants in Producing Colored Paste c) A bstract i. Paste is a type of glue made from starch or dextrin, a starchproduct. This investigatory project shows that we can produce our own colored paste without spending much time and money. That·swhy this Science Investigatory project can help students save their money instead of spending it in buying expensive andcommercialized colored glue. In addition, this colored paste can bean additional source of income. It·s not just affordable; it·s alsosafe and non-toxic because the ingredients used are starch, water natural dyes from plants and alum. Alum is used as preservative toprolong the shelf-life of the paste. Natural dyes from plants like bayabas leaves, taro leaves and carrots were tested as coloring fir this paste. We can also use other coloring from plants byresearching and do further study to improve the quality of thiscolored paste. ii. First, you must prepare all the ingredients. Then, after preparing,extract the color from the plants. You will extract the color pigment of taro leaves and bayabas leaves by sleeping it into half cup of hot water in two separate bowls. In the case of carrots youwill cut it in small pieces using the knife, but be very careful whiledoing this, after cutting it in smaller pieces, you will crush thecarrots using mortar and pestle then put it also in a separate bowlwith hot water in it. After getting the color pigment you will putthe three different natural dyes in the casseroles, then you will putit in a stove, while heating, you will put 3 tease spoons of starchand 2 tease spoons of alum. Stir until it becomes sticky. If it issticky enough remove the casserole in the stove and wait for it tocool. If it is already cooled, you can transfer it in a container.iii. Our findings in our experiment, all of the colored pastes wereeffective in sticking. d) Introduction U sing Natural Dyes from plants in Producing Colored Paste is our investigatory project to make natural colored paste from plants that arenon-toxic. This experiment will help us to recycle and to avoid spendingtoo much money from buying expensive synthetic colors. e) R eview of R elated Literature We base or conceptualized our investigatory project from the HighSchool students in other school in Manila. They perform this experimentwith a huge success because of their patience and a keen-observant. f) Procedure i. Materials 3 Different casseroles 3 Different Bowls Starch Alum (Tawas) Natural Dye (Taro leaves, Bayabas leaves, and Carrots) Mortar and PestleStove Knifeii. Procedure y First, you must prepare all the ingredients. Then, after preparing, extract the color from the plants. You will extractthe color pigment of taro leaves and bayabas leaves bysleeping it into half cup of hot water in two separate bowls.In the case of carrots you will cut it in small pieces using theknife, but be very careful while doing this, after cutting it insmaller pieces, you will crush the carrots using mortar andpestle then put it also in a separate bowl with hot water in it.After getting the color pigment you will put the threedifferent natural dyes in the casseroles, then you will put it ina stove, while heating, you will put 3 tease spoons of starchand 2 tease spoons of alum. Stir until it becomes sticky. If itis sticky enough remove the casserole in the stove and waitfor it to cool. If it is already cooled, you can transfer it in acontainer.
