Abstract

The purpose of this experiment is to be able to help the society with its environmental issues by creating a biodegradable plastic out of Cassava Starch. The researchers will use environment-friendly materials which can be made into biodegradable plastics that will not harm the environment and will not add to pollution problems. Cassava Tubers were ground and squeezed to extract its starch. Starch obtained was weighed and divided into three equal parts; 80 grams in trial 1, trial 2 and trial 3. T1, T2 and T3 also consisted of 60 ml Polyester resin and 50 grams of Polymer MEKP Hardener for T1, 75 grams for T2 and 125 grams in T3. The components in every treatment or trial were mixed, stirred and then poured in 3 different shirts with Petroleum Jelly and then sun-dried. Afterwards, different methods were used to test the effectivity of the plastic. T1, T2 and T3 were sun-dried but they did not look like a plastic at all. The researchers observed the product while waiting for it to dry but there were no signs of turning into a plastic.  The Cassava starch was too thick and the researchers realized that it would not turn into a plastic because of its heavy weight and it would take more time before it would dry because of its thickness. After letting T1, T2 and T3 dry under the sun, it became hard. Although the researchers had unexpected results and the Cassava starch did not turn into plastic, studies have already proven that Cassava starch could be used for making various types of packaging products. Cassava is a promising raw material for the development of biodegradable plastics. The research activities have shown and proven that cassava starch is effective in the development of biodegradable packaging materials such as plastics. Studies determined the effectiveness of cassava starch as component of biodegradable plastic. Results confirmed that cassava starch is ideal as tests proved its worth. Therefore, Cassava Starch is an effective component for Biodegradable plastic.

I. Introduction

Plastics are used because they are very useful, cheap, manageable and handy. Plastics have been the fastest growing basic material because they are versatile, light weight, energy saving, durable and recyclable.  It has become a popular material used in a wide variety of ways. Plastics can last a long time but unfortunately, this same useful quality can make plastic a huge pollution problem. Its long life means it survives in the environment for long periods where it can do great harm. Non-biodegradable plastics are durable but they degrade very slowly; molecular bonds that make plastic so durable make it equally resistant to natural process of degradation.  Plastic packaging provides excellent protection for the product, it is cheap to manufacture and seems to last forever. Lasting forever, however, is proving to be a major environmental problem. Plastics are also a huge problem in waste disposal and studies have been made to find a substitute material which can be used in making biodegradable plastics. Because plastic does not decompose, and requires high energy ultra-violet light to break down, the amount of plastic waste in our oceans is steadily increasing. Studies that have been done locally show about 3, 500 particles of plastic per square kilometer of sea off the southern African coast. The world production of plastic is estimated to be more than 100 million tons per year. Plastics are indeed a threat to wild life. A great proof for this is that plastics have been found in the stomachs of sea turtles, birds, and fish all over the world. Tragically, millions of tons of plastic are poisoning our oceans. Plastic pollution harms people, animals, and the environment because it is non-biodegradable. In the marine environment, plastic breaks down into smaller and smaller particles that absorb toxic chemicals, are ingested by wildlife, and enter the food chain that we depend on. People need alternative and effective components of plastic that is safe and biodegradable which will not harm and pollute the earth.

II. Problem

Could Cassava Starch be an effective component for ideal Biodegradable plastic?

III. Hypothesis

a. If you’d use the starch of Cassava plant as a component of plastic, then the plastic will be biodegradable.

b. If you’d use the starch of Cassava plant as a component of plastic, then the plastic will be non-biodegradable.

IV. Significance of the Study

            This study is important to be able to help Mother Earth in reducing its pollutants and toxic or harmful wastes. Through this study, the researchers will be able to help other people, the animals and the environment. The researchers would like to stop plastic pollution and be part of the solution.  Plastic bags and bottles, like all forms of plastic, create significant environmental and economic burdens. They consume growing amounts of energy and other natural resources, degrading the environment in numerous ways. In addition to using up fossil fuels and other resources, plastic products create litter, hurt marine life, and threaten the basis of life on earth. There is over 45 million tons of plastics per year and nearly every piece of plastic ever made still exists today because of its long-life properties. Biodegradable plastics could be an effective solution to all of these problems. Biodegradable plastics are a much better choice than non biodegradable plastics because they are friendlier to the earth and the environment. Biodegradable plastics break down faster, can be recycled easier and are non-toxic. With these characteristics of biodegradable plastics, we could help save lives and the environment as well and reduce the threat plastics give to marine life. Plastic, the wonder material that we use for everything, is perhaps the most harmful of this trash because it does not readily break down in nature but if it is biodegradable,

Page 2

these plastics break down faster so they have a much shorter effect on the earth, and they will degrade

completely. Normal plastics are manufactured using oil, and this process is very harmful to the environment by polluting the air and environment, but this is not the case with green biodegradable plastics. Using biodegradable plastics will minimize the effects that these products have on the earth, and help eliminate their waste much faster.

V. Review of Related Literature

            In the past few decades, there has been a marked advance in the development of biodegradable plastics from renewable resources, especially for those derived from starch-based materials. The goal of this development is to obtain biodegradable plastics that perform as well as traditional plastics when in use and which completely biodegrade at disposal. Several starch-based plastics have been introduced into the market, and are used in some applications now. Starch foam is one of the major starch-based packaging materials. It is produced by extrusion or compression/explosion technology. This product has been developed as a replacement for polystyrene which is used to produce loose-fillers and other expanded items. Another type of starch-based plastics is produced by blending or mixing starch with synthetic polyester. For this type of biodegradable plastics, granular starch can be directly blended with polymer, or its granular structure can be destructurized before being incorporated into the polymer matrix. The type of starch and synthetic polymer as well as their relative proportions in the blends influence the properties of the resulting plastics. The last group of starch-based plastics is polyesters that are produced from starch. The major starch-derived polyesters in the market now are polylactic acid and polyhydroxyalkanoate. Experimental studies have demonstrated that cassava starch could be used for making various types of packaging products. As a major source of starch in tropical and subtropical regions, cassava is a promising raw material for the development of biodegradable plastics in these areas.

Page 3

Research has been done on biodegradable plastics that break down with exposure to sunlight (e.g., ultra-violet radiation), water or dampness, bacteria, enzymes, wind abrasion and some instances rodent pest or insect attack are also included as forms of biodegradation or environmental degradation. It is clear some of these modes of degradation will only work if the plastic is exposed at the surface, while other modes will only be effective if certain conditions exist in landfill or composting systems. Starch powder has been mixed with plastic as a filler to allow it to degrade more easily, but it still does not lead to complete breakdown of the plastic. Some researchers have actually genetically engineered bacteria that synthesize a completely biodegradable plastic, but this material, such as Biopol, is expensive at present.

The diversity and ubiquity of plastic products substantially testify to the versatility of the special class of engineering materials known as polymers. However, the non-biodegradability of these petrochemical-based materials has been a source of environmental concerns and hence, the driving force in the search for ‘green’ alternatives for which starch remains the frontliner. Starch is a natural biopolymer consisting predominantly of two polymer types of glucose namely amylose and amylopectin. The advantages of starch for plastic production include its renewability, good oxygen barrier in the dry state, abundance, low cost and biodegradability. The longstanding quest of developing starch-based biodegradable plastics has witnessed the use of different starches in many forms such as native granular starch, modified starch, plasticized starch and in blends with many synthetic polymers, both biodegradable and non-biodegradable, for the purpose of achieving cost effectiveness and biodegradation respectively. In this regard, starch has been used as fillers in starch-filled polymer blends, thermoplastic starch (TPS) (produced from the combination of starch, plasticizer and thermomechanical energy), in the production of foamed starch and biodegradable synthetic polymer like polylactic acid (PLA) with varying results. However, most starch-based composites exhibit poor material properties such as tensile strength, yield strength, stiffness and elongation at break, and also poor moisture stability. This therefore warranted

Page 4

scientific inquiries towards improving the properties of these promising starch-based biocomposites through starch modification, use of compatibilizers and reinforcements (both organic and inorganic), processing conditions, all in the hope of realizing renewable biodegradable substitutes for the conventional plastics.

VI. Scope and Limitations

This experiment only covers plastic bags, not including other plastic materials such as plastic containers, plastic cups, straws and other plastic utensils. The experiment can be done in a matter of 2 hours, excluding the sun-drying procedure. Most of the materials used in the experiment are accessible and can be bought in supermarkets. However, there are a few which are not available in nearby stores. Premix Polyester Resin and Polymer MEKP Hardener are manufactured by Polymer Products (Phil) Inc. and can be bought in Bagong Ilog, Pasig City.

VII. Definition of Terms

Biodegradable - able to decompose naturally: made of substances that will decay relatively quickly as a result of the action of bacteria and break down into elements such as carbon that are recycled naturally

Starch – a white, granular or powdery, odorless, tasteless and complex carbohydrate found chiefly in seeds, fruits, tubers, roots and stem pith of plants, notably in corn, potatoes, wheat, and rice; an important foodstuff and used otherwise especially in adhesives and as fillers and stiffeners for paper and textiles.

Plastics – the word plastic is derived from the words plasticus (Latin for “capable of molding”) and plastikos (Greek “to mold,” or “fit for molding”). Plastics are polymeric, moldable and synthetic materials which are derived from fossil fuels, such as oil, coal or natural gas. Plastics consist of organic (carbon-containing) long molecular chains that give them many of their unique properties. They can be made hard, flexible, strong, transparent, light and elastic.

Page 5

Polymer – long-chain molecules that repeat their structures over and over

Polyethylene Bags - the bags that you will see commonly used, such as plastic grocery bags, are made from petroleum byproducts, which is the root of most all of the environmental problems that they are the source of. Not only do they take substantially longer to break down or degrade, but as they do they release highly toxic chemicals.

Resin – It is a hydrocarbon secretion of many plants, particularly coniferous trees. It is valued for its chemical constituents and uses, such as varnishes and adhesives, as an important source of raw materials for organic synthesis, or for incense and perfume.

Polymer Methyl Ethyl Ketone Peroxide (MEKP) - The most popular type of hardener because of its economy and ease of use.

Polyester Resin - Polyester resins are the most commonly used matrix in the marine and composite industry. These resins are styrene-based, flammable and catalyzed when combined with Methyl Ethyl Ketone Peroxide(MEKP).  Polyester resins are unsaturated resins formed by the reaction of dibasic organic acids and polyhydric alcohols.

Premix Polyester Resin R10-60 – It is a fast gel premix polyester resin used for wood, kapiz, and other lamination with cellophane, “Lumirror” or “Mylar” films. It is also used to make decorative jewels and flowers from ceramic molds, to make small coatings from polyethylene & silicone rubber molds, and to cast on intrinsic molds such as steel or bass frames.

Plastic Resin Glue – Plastic resins are made by heating hydrocarbons in what is known as the

Page 6

"cracking process." The goal here is to break down the larger molecules into ethylene, propylene, and other types of hydrocarbons. The amount of ethylene produced depends on the cracking temperature. Once the cracking process has been completed, the compounds are formed into chains that are known as polymers. Different polymers are combined to make plastic resins that have the characteristics needed for different applications. Once the plastic resins have been formed, they are used to make many different kinds of products.

Catalyst - chemical that accelerates chemical reaction: a substance that increases the rate of a chemical reaction without itself undergoing any change

Page 7

B. Procedure

1.      Gather the Cassava Tubers. Ground and squeeze it to extract the starch.

2.      Get hold of 240 grams of the starch and divide it into 3 equal parts: 80 grams in trial 1, trial 2 and trial 3.

3.      Place 60 ml of the plastic resin glue (Premix Polyester Resin) with 50 grams of flour catalyst for T1, 75 grams for T2 and 125 grams in T3.

4.      Mix and stir the components and pour it in the shirt with Petroleum Jelly and let it dry under the sun.

5.      To test its capacity to carry weight, use the plastic to carry objects.

6.      For its ability to hold water, put water inside the plastic.

7.      To test its tensile and bending properties, stretch the plastic as far as you can.

8.      Repeat steps 5-7 using T2 and T3.

IX. Data and Results

            

                                                       

	Amount of Cassava Starch (g)	Amount of Plastic Resin Glue (ml)	Amount of Polymer MEKP Hardener (g)	Did the color change?	Hardness	Can it be peeled from the shirt completely?	Texture of the final product
T1	80 g	60 ml	50 g	No	It hardened but did not turn into plastic.	It can be peeled off the shirt completely	Rough
T2	80 g	60 ml	75 g	No	Hardened a little but did not turn into plastic.	It can be peeled off the shirt but not completely	Some parts are smooth but most of the parts are rough.
T3	80 g	60 ml	125 g	Yes, it changed to color Yellow.	Did not harden at all.	It cannot be peeled off the shirt at all	Some parts are rough but most parts are smooth.

The researchers had unforeseen outcomes. The researchers had 3 trials: T1, T2 and T3. The three trials contained 80 grams of cassava starch and 60 ml of plastic resin glue each. They also put 50 grams of Polymer MEKP Hardener in T1, 75 grams in T2 and 125 grams in T3. The researchers used plastic resin glue because plastic resins are made by heating hydrocarbons where larger molecules is breaking down

Page 10

into ethylene propylene. Once the process has been completed, the compounds are formed into chains that are known as polymers. Polymers are combined to make plastic resins. Once the plastic resins have been formed, they are used to make several varieties of products. Another reason on why the researchers used plastic resin glue on their experiment because based on studies, plastic resin glue dries to a glass-hard consistency depending on the ambient temperature. On the other hand, the researchers used Polymer MEKP Hardener on their research because when it is mixed with the resin, the resulting chemical reaction causes heat to build up and improve or harden the resin to make the product more effective. They used different amounts of MEKP so that the researchers would know if what would work the best, the container with more MEKP or the one with less. After mixing and stirring the treatments, it was transferred on 3 separate shirts with Petroleum Jelly then sun-dried. After 4 hours of observing the conducted experiment, their products hardened but did not look like it would turn into plastic like they have been expecting. T1 is the hardest of them all hence, it can be peeled off the shirt and since T3 did not harden, its texture is smooth and it cannot be peeled off the shirt in any way. T2 hardened a little but still did not look like plastic. Some parts are smooth but most parts are rough. It can also be peeled off the shirt but not completely. In order for us to test its capacity to carry weight, we used the plastic to carry objects, we also tested its tensile and bending properties, T1 had the best result for both. We also tested for its ability to hold water by putting water inside the three trials, none of our trials worked. In view of the fact that the thickness of the cassava starch on the shirt is a factor why the outcome didn’t work as expected. The cassava starch was not spread evenly making it so thick, thus, the cassava starch being too thick means it would also be difficult for it to dry. 

Page 11

X. Discussion and Analysis

            The researchers have studied the final product of all three trials and have observed that: In the first trial, the researchers have observed that among the three trials it was the most successful because of the hard and sturdy layer it produced. It was strong enough to carry objects but it can also be bent without breaking. Even when it was peeled from the white cloth it did not break down. The researchers believe that trial one would be the most reasonable and efficient trial to use for a biodegradable plastic. In the second trial, the researchers observed that the final product was somewhat not as whole as trial one. It made a rather sticky substance that was very flimsy and fragile, especially when it was peeled off the white cloth. In the third trial, the researchers have observed the looseness of the final product. Though it has been sun dried, it kept its damp and very sticky attribute. It showed since of being very flimsy and loose. When trial three was peeled of it easily broke down because of its very gooey feature. The researchers believe that trial three would be the most inefficient trial to use for a biodegradable plastic because its lack in plastic features.

            The physical properties of plastic include transparency, flexibility, elasticity, permeability, ductility, electrical resistance and its ability to hold water. The researchers observed that the final products lack plastic properties. None of the 3 trials were transparent and for its flexibility, it was only T1 that can be bent without getting destroyed. Though T1, T2 and T3 lack those properties, it can still be considered as an effective component for biodegradable plastics because they are biodegradable.

            Studies have already proven that cassava starch is an effective component of biodegradable plastics. However, the end product of the experiment did not look like a plastic at all. The researchers had altered the suggested procedure found on the internet. The procedure was not also vey precise and specific. A factor that might have affected the results was the use of chemicals. The shirts, petroleum jelly, Polymer MEKP Hardener were only used as substitutes for the actual materials. The shirt was used

Page 12

to replace silk screen and Petroleum Jelly was used instead of oil. Polymer MEKP Hardener was used a substitute for the flour catalyst. Also, the appropriate type of Plastic Resin must be selected to make the particular type of product needed but in the procedure, no type was specified so the researchers used Premix Polyester Resin. There were lots of flaws in the experiment which probably was the reason why the researchers failed in the experiment. The cassava starch was not also ground and it was the reason why it was thick and it was not also spread thoroughly. The weather was also a factor because sunlight and heat was really needed for the cassava starch to dry but then, it was not too sunny.

XI. Conclusion

            Even though the researchers had unanticipated outcome, they still conclude that Cassava starch can be used as a biodegradable polymer to replace plastics in packaging materials. Cassava starch can be applied for the production of biodegradable plastics. Starch can be incorporated into plastics to improve the biodegradability of the plastic and finished product. According to different studies and research, cassava starch could be used for making a range of types of plastics and is now being used in the market. Cassava has a promising raw material and its starch have the characteristic of being able to absorb humidity, just like normal plastics. It’s also has a low bulk density and only a little modification is needed to increase its moisture content which is needed in producing plastics. Since starch is a natural polymer and is biodegradable, it can play as an important role in the biodegradable plastic manufacturing. Therefore, Cassava starch is an effective component in biodegradable plastics.

XII. Recommendations

            Although the researchers were not successful in this experiment and had unexpected results, they still recommend this topic which can be used in Investigatory Projects. For those who are interested in this topic and would like to perform this experiment in the future, the researchers are suggesting that you should follow the right procedure and be accurate with your measurements. People should have sufficient

Page 13

background information about the chemicals that they will be using and they make sure that they areusing the right materials or chemicals. Remember that little factors might affect the outcome so you should be careful in performing the different steps. Future experimenters should clarify the procedure and make sure that the ingredients that you will be using as substitutes will be effective in this project.

"Ang aking Talambuhay"

ANG AKING TALAMBUHAY

ang aking Binyag

"ako at ang aking mga pinsan"

Noong ika-dalawampu’t isa ng Marso taong 1998 ng ako’y ipanganak sa St. Gerald Hospital sa Lungsod ng San Pablo. Ako si Maria Carmella N. Vibal, panganay na anak ni Julian B. Vibal at Eden N. Vibal at ang  kapatid nina Rhonald N. Vibal at Jhuliana N. Vibal.
Lumaki ako sa Purok Labak ng aming barangay, ang Barangay Bautisata San Pablo City, Laguna. Ang aming tirahan noon ay malapit sa tabing ilog at nasa may paanan ng bundok.

"Unang araw ng pasukan" 

Naaalala ko pa na noong ako’y bata pa lamang ay para akong batang lalake kung maglaro noon sapagkat lagi akong kasama nig aking mga pansin sa paglalaro ng piko, patintero, sikyo, finish line, baseball, sipa, badminton at kung anu-ano pang laro. Tuwing mayo naman  at may libot sa aming purok ay gabi-gabi kaming naglalaro ng taguan kasama pa ang ilang bata. Kung minsan naman ay gumagawa kami ng saranggola at kasama ko sa papa lito sa pagpapalipad nito doon sa may taniman ng intsik. At pagkatapos na magpalipad ng saranggola ay kumukuha kami ng mga dalanghita na daladala naming pag-uwi sa bahay. Tuwing walang pasok naman ay kasama ko an gaming kapitbahayna babae na si grace bael para maglaro ng habulhabulan sa may bundok, paglalaro ng lastiko na plaging uso sa amin noon at kung minsan naman ay kasama ko siya sa panghuhuli ng isda  at paggagawa ng labahan sa ilog kasama ang ibang pang bata.

At noong limang taong gulang na ako, noong taong 2003 ay nagsimula akong umasok ng kinder. Dahil ng mgapanahong iyon ay hindi pa uso o wala pa noong prep at nursery sa aming barangay.

Hindi ako kinabahan noong unang araw ko ng pagpasok dahil nakita ko na ang mga kaklase ko ay ang mga kalaro ko sa amin  at ang Naaalala ko pa nga na noong limang taong gulang ako ay pinagpiplian kaming dalawa ni Kuya Jay Vince  kung sino ang lalaban sa gaganaping paligsahan / patimpalak sa larangan       ng Matematika. Kaya naman upang mapili ako sa Math Quiz ay lagi akong sumasama sa aking lola tuwing siya ay naglalaba sa ilog upang akoy maturuan niya.

At hindi nasayang ang pagsama ko kay inay, dahil napili ako ng aking guro na si Ma’am Arlene upang lumaban. Bagamat hindi ko nakamit  ang karangalan bilang pinakamahusay na kalahok sa nasabing paligsahan, masaya parin naman ako dahil napili ako ng aking para sumali sa ganoong paligsahan.

kindergerten

Kaya naman noong ika-26 ng Marso taong 2004 ay nakumpleto ko kaagad ang aking kindergarten course kung saan tinanggap ko ang sertipiko sa mababang paaralan ng Don Enrique Bautista.

Nang mag- aaral sa paunang baiting sa Fernando A. Quisumbing Elementary School ay pinapapili ako ng aking lola kung saan ko gustong pumasok ng grade I kay Ma’am  Mylene Seksyon A o kay Ma’am Alcantara Seksyon B, kahit na alam kong mas mataas ang seksyon A ay mas pinili ko ang seksyon B dahil noong nag-aaral pa lamang ako ng kinder ay lagi kong nakikita si Kuya Ryan, ang aking pinsan na pumapasok kay Ma’am Alcantara at gusto ko rin ay doon ako papasok.”

Dahil   nga mas pinili ko ang mapapunta sa  seksyon B [GRADE -1 PANDAN] ay hindi  na ako nakasali sa ilang mga paligsahan sa paaralan dahil kinukuha ang lalaban sa Seksyon A. Ngunit bagamat seksyon B lang ako ay sumali parin ako sa ilang mga events katulad na lamang ng camping sa Girl Scout. Samantala isa naman sa mga pangyayari noong ako ay Grade 1 na hinding hindi ko malilimutan ay noong akoy nabunggo ng jeep habang nakikipag – unahan sa pagsakay upang makalibre lamang ng pamasahe at hindi maglakad. Mabuti na lamang at nakita ako ng ilang mga guro na may dugo ako sa aking noo, kaya naagapan ang pagdurugo at hindi na ako kinailangang dalhin sa ospital

"Recognition Day"

Noong akoy pitong taong gulang na ay muli akong pinapili ni inay kung saan ko gustong  pumasok at muli kong pinili ang seksyon B dahil bukod sa nadodoon ang mga kaibigan ko, e doon din pumasok si Kuya Ryan noong siya ay grade II.Naging Guro ko si Mrs. Devega noong ako’y nasa ikalawang baiting na ng aking pag-aaral. At kung noon ay hindi ako nakakasali sa mga patimpalak ng paaralaan para sa District Meet noong grade II naman ako ay napili na ako bilang kalahok sa MTAP Quiz Bee kung saan nakasama ko roon sina Marjorie at Raven habang kami ay nagrereview bilang paghahanda sa gaganaping patimpalak. At nang mga panahong iyon ay nagging magkakaibigan kaming tatlo.

Kung noong ako ay grade I palang ay nabunggo ako ng isang jeep, noong grade II naman ako ay nahabol ako ng taga ng isa kong kaklase si Jay-are Tesalona. Hinding hindi ko malilimutan ang pangyayaing iyon kung saan ay naihulog ko ang kanyang bag habang naglalaro ako ng habul-habulan kasama ang aking mga kaklase sa loob nang classroom. At ng makita niya iyon ay kumuha siyang itak at kami ay hinabol ng taga. Mabuti nalang at may nakakita sa kanya habang kami ay hinahabol kaya naman walang nangyaring masama.

Samantala noong ako naman magkatatapos na ng pag-aaral bilang magaaral sa ikalawang baiting ay pinarangalan ako bilang pinakamahusay na mag-aaral sa aming klase.

"Recognition Day"

At kung noong Grade I at Grade II ay pinapipili ako ng gusto kong seksyong papasukan noong Grade III naman ako ay hindi na ako pinapili dahil inilipat na kaagad ako sa seksyon A upang malaman daw ang aking kakayahan na makipagsabayan sa iba pang mag-aral. Doon ay nakilala ko pa ng mabuti sina Marjorie Anguluan at Raven Navia  at ang ilan pang mga mag-aaral katulad nina Aira Carro, Queenie Carro, Zyine Balitaan, Jobelyn Manalo, Unices Manalo, Wendel Bael, Matthew delas Alas, Norman Capila at iba pang mga estudyante. Kaya naman madalang ko nang nakakausap ang dati kong mga kaibigan at mga kamag-aaral.

At sa pagtatapos ng taon, ako ay tinanghal bilang pang-anim na pinakamahusay na mag-aaral sa aming klase. Bagamat mas mababa ito kung ikukumpara sa dati kong rangko noong isang taon ay ayos lamang iyon sa akin. Bagkos ay mas pinagbuti ko pa ang aking pag-aaral at sumali ako sa iba’t ibang patimpalak sa paaralan.

Sumali muli ako sa ibat ibang paligsahan sa aming paaraan.  Noong ako ay siyam na taong gulang na at nasa ika-apat na baiting na ng pag-aaral ay mas dumami ang sinalihan kong mga paligsahan tulad na lamang ng Math quiz bee at MTAP  quiz bee, mas nagpusige kong mag-aral ng mabuti hanggang sa pagtatapos ng taon ay tinanghal ako bilag ikalawang pinakamahusay na mag-aaal at huwaran sa kalinisan.

Noong sampumg taong gulang na ako at pumapasok na bilang mg-aaral sa ikalimang baiting ay na-elect ako bilang treasurer ng aming klase, isang posisyon na noon ko lamang nahawakan. Sumali muli ako sa mga paligsahan ng aming eskwelahan ulad na lamang ng HEKASI (Heograpiya, Kasaysayan at Sibika) quiz bee at MTAP quiz bee. Sumali rinako sa ilan pang mga events na ginanap sa mga paaralan o pangkalahatang distrito at dibisyon.

Ngunit sa pagtatapos ay nahirang akong pangatlong pinakamahusay na mag-aaral.

Noong labing isang taong gulang na ako at nasa ikaanim nang baiting, ay na-elact at nanalo muli ako bilang treasurer ng aming klase at Vice President ng aming paaralan.araos ng Coco Festival ay sinalihan ko rin, kung saan naranasan ko ang matinding pagod at pawis habang nagsasayaw sa kalsada.

"araw ng pagtatapos"

At sa aking pagtatapos bilang elementary student ay tinanghal ako bilang ikatlong pinakamahusay na mag-aaral.ang araw na iyon ang masasabi kong araw na hinding hindi ko malilimutan bilan elementarystudent sa paaralan ng Fernando A. Quisumbing Elem. School.

Nang papasok na ako nang highschool ay tatlong paaralan ag aking pinagpipilian(San Pablo City Highschool, San Bartolome National Highschool at ang Col. Lauro D.Dizon Memorial National Highschool). Sa katunayan ay kumuha pa nga ako ng exam sa City High para sa science section ngunit kahit hindi ko pa alam ang resulta ay napili ko na kaagad ang Dizon High  dahil mas maami akong kakila roon at nadodoon rin ang ilan kong pinsan katulad ni Kuya Jopet at Ate Rio.

At laking pasasalamat ko ng makapasok ako sa science section nang bigyan ako ng pagkakataong makakuha ng exam para makapasasa naturang seksyon. Bagamat nakapasa ako sa Science Section ay hindi pala iyon ganoon kadali. Dahil hindi tula nila, wala akong kakilala sa seksyon na yon bukod kay Meryl, na dati kong kasama sa mardigra. Pangalwa, hindi tulad nila wala akong karanasan o  kaalaman sa paggamit ng computer. Sa katunayan pa nga, ang unang pasok ko sa computer room ang unang hawak ko sa computer upang matuto kung paano ito gamitin. Bagamat ganoon ang nangyari madali naman akong naka-adapt sa kanila at hanggang naging kaibigan ko narin ang ilan sa aking mga bagong kaklse. Natuto akong humawak at gumamit ng computer. Ang mga ito’y hindi naging sagabal upang makipagsabayan ako sa kanila upang matuto at mag-aral ng iba’t ibang leksyon o aralin.  

         Hangga’t kaya ko ay ginawa ko ang lahat ng requirement para makapasa, maka-adapt at para hindi ko maisip ang ilan sa masasayang alaala ng taong ako ay nasa elementarya. Kaya naman pinarangalan ako sa pagtatapos ng taon bilang ikapitong pinakamahusay na mag-aaral.

       At kahit ngayon nasa 2^nd year highschool at labing tatlong taong gulang na ako, lagi kong naaalala ang masasayang bahagi ng aking buhay bilang bata, mag-aaral, kapatid at anak. At ang mga alaalang iyon ay hinding hindi mabubura  kahit sa paglipas ng marami pang mga taon.
