Investigatory proj free essay sample

The researchers thought of using eggshell, styrofoam and gasoline as a sealant. To make the sealant, the researchers put the styrofoam in the gasoline and melted it by stirring the gasoline. After stirring, the pounded eggshell was mixed. The researchers conducted four experiments. The commercialized sealant and the eggshell sealant were observed in it’s durability, sealing ability, physical appearance and insolubility. The researchers observed the results and discovered that if the hole in the roof was lesser in diameter, it was durable and if the diameter was greater, the sealant was less durable. The researchers considered the time it took to dry. D. Introduction Today, rain is a big deal to everyone. If there are news that rain is coming soon, everyone often think that it is a new problem to be encountered. It maybe can cause landslides, floods or even can make everyone worried because of the holes in their roofs. We will write a custom essay sample on Investigatory proj or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In order to solve one of those problems, the researchers investigated about the eggshells with styrofoam and gasoline as a substitute to commercial sealant. The researchers came up with this problem because as the researchers observe in their houses now, plenty of their roofs had holes. Instead of buying commercial sealant, anyone can just recycle their styrofoam, eggshells and make it a sealant. The making of this substitute sealant can give a big benefit to the community especially the people who can’t afford to buy the commercialized sealant. It will also give a great for the school whenever there are styrofoams that will not be used. The school does not need to worry of what to do. It will also serve as a great help to the next generation of researchers whenever the next researchers would want to make a sealant. The next researchers could get ideas of this project so that it will be more effective ad be very easy to make. This study is only limited in the Styrofoam because styrofoam can be melted by the gasoline. People cannot just use any plastic material instead of Styrofoam because it can be melted by the gasoline. That’s why the researchers used Styrofoam. E. Review of Related Literature ?Can bonaw shells be an effective additive in preparing sealant? † This was the problem the researchers had found which was related to the researchers’ study. Katrina Loisse Cabugnason and Cocon Rusiana, the proponents of this study. The researchers conducted a study that bonaw shells(Callista erycina ) can be an effective additive in preparing sealant, which is cheap and easy to make. In testing the effectiveness of the sealant, two experiments were conducted. A commercialized sealant and the bonaw shell sealant were compared in terms of sealing ability and rate of time it took to dry up. The result showed that sealant from bonaw shell is as effective as the commercialized one. The researchers and the proponents of this study differ in shells that were used. The researchers used the eggshell while the proponents of this study used the bonaw shells. F. Procedure This research uses the following materials: Eggshells Cup with gasoline (250 ml) Styrofoam 1 empty sealed bottle (glass) 1 empty cup The researchers gathered their eggshells and styrofoam by asking from their relatives, friends, etc. They bought the gasoline that they use in the Gasoline Station. The researchers had the following steps: Gather the eggshells, styrofoam and the cup of gasoline. Pound the eggshells and put it in a cup. Dissolve the styrofoam to the cup of gasoline and stir it well. Mix the pounded eggshells to the cup of gasoline with styrofoam. Put the finish product in a glass. G. Results and Discussions Table 1 Durability of the sealant SEALANT DIAMETER AFTER 1 hr. AFTER 3 hrs. AFTER 5 hrs. Eggshell with sealant 0. 25 cm durable durable durable Commercialized sealant 0. 25 cm durable durable durable The Table 1 shows that in 0. 25 cm, eggshell and commercialized sealant are durable after 1,3 to 5 hrs. Table 2 Sealing Ability Kind of Sealant RESULT Eggshell sealant No leakage Commercialized sealant No leakage The Table 2 shows that the sealing ability of the commercialized sealant has no leakage as well as the eggshell sealant. Table 3 Physical Appearance (color and texture) KIND OF SEALANT COLOR TEXTURE Eggshell sealant pinkish with dotted white rough Commercialized sealant gray smooth The Table 3 shows the color of the eggshell sealant is pinkish with dotted white; it’s texture is rough while the eggshell sealant is gray and it’s texture is smooth. Table 4 Insolubility of each sealant KIND OF SEALANT Eggshell sealant insoluble Commercialized sealant insoluble The Table 4 shows that the eggshell and commercialized sealant are both insoluble when soaked in water for 45 mins. H. Conclusion The sealant made from eggshells is durable after 1,3 to 5 hrs. ,when applied in hole with 0. 25cm in diameter. It has a sealing ability with no leakage, pinkish with dotted white in color and rough in texture. It is insoluble when soaked in a water for 45 mins.. The commercialized sealant is durable after 1,3 to 5 hrs. when applied in hole with 0. 25 cm in  diameter. It has sealing ability with no leakage, gray in color and smooth in texture. It is insoluble when soaked in water for 45 mins.. Therefore the researchers concluded that the eggshells with Styrofoam and gasoline can be substitute to commercial sealant which makes the first affirmative hypothesis to be accepted. I. Recommendation The researchers recommended this project to the next generation of researchers as a guide and for the betterment of the project. The researchers also recommend the next researchers to conduct further experiment to improve the product.
