This chapter contains the following: the background of the study, rationale, objectives, the statement of the problem, hypotheses, significance of the study, scope and delimitations, and the definition of terms. Background of the Study.
Paper, as we all know, is a vital object in our lives. Paper has reinvented the way we communicate, record history, and write down literature. Paper is portable, smaller, and thinner, and has triggered the inventions of new cleaning products, printing, and even foods.
Paper however is made of pulp from trees, but due to acute need of paper and other tree-made objects millions of trees had to be cut down. Trees, which we need to combat the greenhouse gases, provide oxygen, preserve soil, etc. The Ananas Comosus is a tropical plant that is usually consumed as a food. But apart from consumption as a food, Ananas Comosus is a versatile crop in which all parts can be used in different purposes.
Rationale of the Study. World consumption of paper has grown percent in the last 40 years. Besides what you can see around you, paper comes in many forms from tissue paper to cardboard packaging to stereo speakers to electrical plugs to home insulation to the sole inserts in your tennis shoes. In short, paper is everywhere. Objectives of the Study. Pineapple leaves from the native and Hawaiian varieties were digested using alkaline-sulfite process to develop pulp and hand sheets for paper making.
An overall assessment showed that dried pineapple leaves produced good quality pulp. Highest percentage pulp recovery I hate frogs, they are so awful. The blended hand sheets of pineapple and abaca pulp could be used as novelty paper, calling cards, greeting cards, art paper and other decorative paper Barnes, Knowing this information, disregarding abaca pulp in the formulation, this study aims to:.
Determine if paper made from Ananas Comosus can be written on and used as a paper for scrapbooks. Statement of the Problem. Specifically, this study seeks to answer the following queries:. Is paper made from Ananas Comosus potent enough to be used as a substitute paper for scrapbook making with regards to the:. Is paper made from Ananas Comosus sturdy enough to be used for writing? From the stated problems, the hypotheses made were:. Significance of the Study. This investigative project is important in order to determine if paper made from an Ananas Comosus can be written on and if it is potent enough to be used as a substitute for scrapbook making.
Also, this study will contribute greatly for the reduction of the number of trees cut down for the creation of paper. Specifically, this research would be of help to the following:. The main aim of this study is to lessen the amount of trees cut down for the production of paper by creating another way to produce paper.
Our environment will highly benefit from this study. Knowing this information will also lessen the amount of money they would have to use for their projects. Common People. People can make paper made from Ananas Comosus to create scrapbooks which they can sell and enable them to have another way to get additional income. Paper Making Industries.
Paper Making Industries would have another way of making paper, which would enable them to produce more paper without having to cut thousands of trees. Scopes and Delimitations. This study is limited only to the use of the Ananas Comosus.
No other plants were used.The Feasibility of Malunggay leaves Moringa Oleifera. Pesticide making is popular nowadays and it is also very helpful in our world in the field of agriculture. Thus many people continue to experiment pesticides to produce better quality and quantity. Pesticide can be applied to the treatment of an organism, such as a crop or ornamental plant, against damage by other plants, insects, fungi, or animals. The researcher aims to produce pesticide out of malunggay leaves and chilli fruit which is known in our country.
And is very useful to many people and also to have another alternatives of pesticide. The process in making pesticide was quite difficult and simple. First are you had to prepare all the materials needed. Second get the extract of the malunggay leaves and chilli fruit.
Nextmix the the extract of the malunggay leaves and chilli fruit. After that store the solution in days and aging process will then be continue. The data and observation gathered is clearly state that the malunggay leaves and chilli fruit as pesticide is easily be contaminated when aging and the researcher therefore conclude that the malunggay leaves and chili fruit is feasible in making pesticide.
Background of the Study:. A pesticide chemical can rarely be used as originally manufactured. The pesticide must be diluted with water, oil, air or chemically inactive solids so that it can be handled by application equipment and spreas evenly over the area to be treated. It includes cockroach killer. It grows wildly in a hot tropical climate. Both the leaves and fruits are very nutritious, which contain many vitamins like Vitamin C and other minerals.
Chili, the name, which is spelled differently in many regions chili, c hile and chilli. The term chili in most of the world refers exclusively to the smaller hot types of capsicum. It is a hot pepper. Even though chilis maybe though as vegetable, their culinary usage is, a generally spice, the part of the plant that is usually harvested is the fruit.
The researcher conducted the study to find out if the malunggay leaves and chilli fruit could be utilized as a pesticide. And determines the effect of malunggay leaves and chilli fruit to the cockroach. Statement of the Problem:. This study lies to find out the feasibility of malunggay leaves and chilli fruit as pesticide. Is there a difference on the effect of malunggay leaves and chilli fruit and the commercial pesticides in terms of:.
There is no significant difference between the malunggay leaves and chilli fruit pesticide and the commercial pesticide. There is significant difference between the malunggay leaves and chilli fruit pesticide to the commercial pesticide. Significance of the Study:. Cockroaches are one of the pests in the country that carries bacteria to people. They give people diseases as well as it can harm and suffer from these diseases and causes death.
So people must kill cockroach. On the other hand malunggay leaves and chilli fruit is also a good source of pesticide like capsaicin, rubefacient, sulphur-containing amino acids and others. Hot chillies makes effective the pesticide and it helps. Thus this study was conducted to utilize malunggay and chilli as necessary components to kill cockroach rather than just ignoring it.
Based on research this plant is good for healing and treating wounds and other skin infections. Stop Using Plagiarized Content.
People, researchers, scientists were focusing to medicinal plants. They want to prove that there are plants that are more effective against diseases especially in skin. This study refers to a plant that can be made into a bathing soap and improves its quality while using this plant guava leaves. I want people to handle easily in treating their skin disorders.

Yes, the extract of the guava leaves can be used in making soap and can be used on treating acne my acne has lessen for I applied it on my face for a week.
You can make a bathing soap with guave leaves extract as treatment for acne. This plant is very common to our environment, and aside of its avaibility; it is easy to cultivate. It contains many components for healing skin disorders. The study of guava leaves and getting their extract is often useful.
It has the ability to treat, cure, disinfect skin disorders and capable of being a herbal plant for acnes. Prepare the stove to be used. Boil it for 10 minutes Low Heat ; Separate the skin from the extract.Go for a walk outside on a nice day to collect leaves and get a closer look at the changes that are taking place around you with the change of the seasons.
Your nature walk will be more fun if you bring someone along to help you collect and observe. When you get home, press the leaves between sheets of newspaper and some heavy books for a few days until they dry out.
That way they will stay flat and keep their beautiful colors instead of curling up and looking dead. Compare them to the leaves you gathered that came from trees that do lose their leaves. How are they different? How are they similar? Compare these leaves with the needles and leaves you gathered from trees. Did you find any leaves from plants that were changing color?
Guava Leaves Investigatory Project
Some plants that are not trees have leaves that will change colors and fall off, but most of the time, the whole plant that is above the ground will die and grow back from its roots in the spring. Most animals, plants, and trees are preparing for the winter during the fall months. Squirrels are gathering and storing food and finding homes that will provide them with shelter from the cold.
Plants lose their flowers and leaves, or else start to die, even though their roots might live through the winter. Except in very warm places, trees are losing their leaves to prepare for winter. Some trees also drop their seeds in the fall. The seeds get buried in the ground sometimes they just get covered up by falling leaves where they will be protected until springtime when they can start to grow into new trees.
Grass also starts to turn brown as it gets colder. The alcohol and the heat from the hot water made the color in the leaves dissolve so you could see it in the alcohol. It is similar to what happens when you make tea.
When you put a tea bag filled with tea leaves in a cup of hot water for a few minutes, the water becomes colored and flavored by the tea leaves.
When you put the paper strips into the green-colored alcohol, the colors started to get soaked up by the paper and you should have seen a couple different shades of green. If you waited long enough, you might have been able to see other colors from the leaves appear on the paper — such as orange or yellow.
If you saw colors besides green, those the are colors that the leaves will change to in the fall! Did you see any difference in the colors from the different kinds of leaves you tested? When you put the paper into the alcohol solution, the colors had a chance to separate, and the orange and yellow are were no longer covered up by the green. The same thing happens when leaves start to change colors — the chemical that makes them green starts to go out of the leaves, leaving the chemicals that make other colors behind, turning the leaves all the pretty colors of fall!

See the Web Link to the left for the information. Some avocado leaves are toxic, so you need to be sure of the type you have.Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be. After you've created your hypothesis or proposal, you can conduct a controlled experiment using the scientific method to arrive at a conclusion.
For those of us who have forgotten the various steps of the scientific method, let me clear that up right here:. Remember, however, that a successful investigatory science project does not necessarily have to result in the intended outcome.
The purpose of these projects is to think critically, and if the solution doesn't work out, that doesn't mean your project will fail. In order to conduct a great investigatory experiment, you have to ask an interesting question and be able to conduct an experiment that can hopefully answer that question.
The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be. I've listed a few examples below of some of the best investigatory experiments out there, so hopefully you'll have no problem coming up with an idea. Basic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies?
This is a great question that makes you think about scientific alternatives to store-bought soap. Below is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen.
We all know how lucrative the oil business is, but what if the next huge innovation in oil was sitting right inside your kitchen cabinet? With the high prices of regular gasoline and diesel fuel, the possibility of creating a usable diesel fuel from household cooking oils is pretty exciting. Although creating diesel fuel out of cooking oils that will run a BMW may sound like a reach, it still makes for a great project.
And who knows, maybe in doing this you'll actually figure out what was missing from previous attempts. Being an instant billionaire doesn't sound too bad to me. If you're interested in trying it for yourself, there's a great step-by-step guide with a full ingredients list and photos over on Make. If biodiesel isn't your forte, you can try making oxyhydrogen gas or creating hydrogen gas via electrolysis or vice versa, creating electricity from hydrogen gas.
Speaking of oil, if you use it to cook, you know that a lot of it goes to waste. But what if you could clean that oil and use it over and over again?Unless you're a high-schooler building a nuclear fusion reactorthe hardest part of a science investigatory project often is coming up with a good idea. You want it to be cool yet feasible, novel but still useful. That's why Ai-ni Bautista 's science project on making liquid soap infused with guava leaf extract is so perfect — it's fun, easy, and fresh with a very practical outcome.
This do-it-yourself soap will smell of lavender and guava, of course and even has health benefits for your skin.
Guava leaves contain phytochemicals that are astringentallowing them to tone and tighten your skin. Guava leaves can also protect against ultraviolet radiationa "major environmental factor" in "skin wrinkle formation and hyperpigmentation. To make it even easier to ace your science investigatory project, we've deconstructed this chemistry experiment into step-by-step instructions.

Since the video has been made publicly available online, you can go right ahead and use it for your science fair or project — no need to ask permission! This experiment will involve working with both sodium hydroxide and extremely high temperatures, so it will require safety precautions and definitely adult supervision.
This guide will cover the important safety measures, but you can also read more about sodium hydroxide safety. If the below information seems a little intimidating to you, you can try making hard soap instead of liquid soap.
It's a little less involved, requires fewer ingredients and equipment, and is just as good as a science investigatory project. For details on that, check our full guide. Make sure that none of the equipment you use contains aluminum, tin, or zinc because lye will corrode all of those metals — and potentially produce highly flammable read: dangerous hydrogen gas.
Stainless steel would be ideal. The sodium hydroxide may also produce fumes, so as much as possible, this experiment should take place outdoors or under a fume hood. If that isn't an option, make sure the room you use is well-ventilated switch on the kitchen fan and open every window you can.
The following guide will make enough soap to fill a bottle of hand soap, so adjust your proportions accordingly if you want to make more. Bring approximately 8 oz.
Keep the water at boiling temperature, and stir occasionally.
Guava Leaves Investigatory Project
After half an hour, take your pot off the stove, strain out the guava leaves, and transfer the guava leaf extract to a container. You can use a sieve or a pair of utensils. At this stage, you're going to prepare a mixture of water, oil, and your chosen scent and food coloring you're going to add the sodium hydroxide to this later, making your soap. The ratios we've provided here are based on a recipe that Ambra, a soap-making hobbyist from Iceland, posted on her blogbut you might want to tweak it with some trial-and-error to get the soap to the consistency you prefer most.
It's true. Oil and water don't mix — they're immiscible together. Heck, most definitions of "immiscible" even use oil and water as their illustration.
That's why you usually need a chemical emulsifying agent to completely combine oil and water, but heating your oil-water mixture, which is our next step, will achieve a similar effect. Add about 8 oz. For soap-making, measure all your reagents by weightand not volume, because the density of different oils can vary significantly.
The mixture should immediately begin to form micellesbubble-like concentrations of oil, especially at the surface. Cover and bring the mixture to a boil, removing the lid to stir occasionally.
Your oil-water mixture should be bubbling from the heat, but better combined than before. Stir, then add the guava extract. Stir again, and add scented oil, and then the food coloring. We suggest adding the food coloring in small doses while stirring, as it takes a while for the coloring to disperse and arrive at a settled color.
Throughout this process, keep your mixture at a boil. Boil for 30 more minutes.
