...For my egg drop experiment, I decided to create my own design. The way I did it was I wanted try and lessen the impact on the fall. How I did that was I put a lot of pressure on the egg. My design was basically two medicine attached together with three skewers. Once I made this I wrapped my egg in plastic wrap then I put the egg in between the two medicine cups and then I taped them together really tight. After this I put a plastic cup inside the mayonnaise container. The plastic cup was just so that when I put the egg in the mayonnaise container the bottom medicine cup wouldn’t touch the bottom of it. This lessened the impact. When I dropped the egg, it made a very loud noise. This scared me a little bit because it didn’t sound good. When...

...The experience of the egg drop project was one that will help you realize that not every way that you try will work, and just because you fail once doesn't mean you can't try again. I believe my egg broke possibly because when I was testing mine I was working with a larger egg. So when it came to the drop it wasn't supported by the walls as much as it should have been. I believe also because the straws on the bottom didn't really reach the egg since it was a smaller egg than what I was practicing with. I feel if I had also dropped it a couple more times or had made it a tiny bit smaller it might have concealed the egg better , and hopefully wouldn't have cracked than.I believe also that when it came to the test it didn't land straight on...

...The Egg Drop project consisted of a few different materials that lessened the egg’s force of impact on the earth. The materials used were: two toilet paper rolls, nine and a half straws, and a half piece of printer paper. Other materials used were: very strong glue and masking tape to hold the contraption together. The egg never touched the ground, which lessened the force on it. Instead of the egg receiving the maximum force of the cement, the materials around it did. The outside materials were very important for this project to be successful because they were much stronger, and provided a lot more support than the egg alone. The main feature of the container that lessened the force when it came in contact with the earth...

...RESEARCH DESIGN A. Definition Research design refers to the complete sequence of steps to be undertaken to ensure that the appropriate data will be obtained in a way which permits an objective analysis leading to valid inferences with respect to the stated problem. It is a step in problem solving consisting of a detailed plan to be followed in obtaining the needed data. It specifies what organisms, chemicals, glasswares, and equipment will be used in the study. B. Significance 1. It serves as a guide for direction during the actual experimentation. 2. It allows a gain of maximum information relevant to the problem at minimum cost. 3. It makes the statistical test of significance valid because it takes into consideration all the assumptions that went into deriving the various statistics. C. General Features The design of an experiment depends on the type of research undertaken and the nature of the conditions under which study is done. The design of an experiment is dictated by the question it is to answer. There is no common blueprint that will serve as a guide in writing a research design. Each problem requires its own unique design. A research design contains the following sections: I. Introduction A. Background of the Study B. Statement of the Problem C. Significance of the Study D. Scope and Limitation of the Study II. Review of Related Literature III. Methodology IV. Time Table V. Proposed Budget ...

...hypotheses. This paper reviews the research conducted on orang-utans/pinworm associations and critically evaluates its successes and failures. Extraction methods Firstly is best to address how pinworms are extracted. Extraction provides identification and quantities of nematodes for use in population studies, leading to dependable approximations of age-structure and sex proportions (Ferris, 1987). Several methods exist, i) the Baermann wet funnel; ii) decanting and filtering techniques; iii) Flotation by a continuous torrent of water (Schouten and Arp 1991). Each extraction method suffers from nematode losses (trapped on sieve, funnel wall). The Baerman funnel has one of the highest extraction success (Son and Moon 2012) with as high as 80%, making this method highly practical. Nevertheless since this method relies on nematode migration it can be affected by temperature (lessening its efficiency). Though under controlled laboratory surroundings temperature extremes should not present a problem. Another way to obtain pinworm eggs is to place adhesive tape around the perianal area. The tape can be then placed onto a microscopic slide for authentication. Additionally faecal nematodes can be analysed by using an agar plate for isolation and a successive examination (hatching test) to determine the viability of eggs (Garcia 2009). Mode of infection and symptoms Of the genus Enterobius transmission occurs primarily when the infective larvae (eggs) are ingestion (Cook 1994). The Life...

...Madelyn Lashinis Term Paper Article Summary Sexual Selection: Pipefish In this research, they looked at many observations that took place with sexual selection in pipefish. They looked into how and where breeding took place, how long the cycle of sexual selection took, and how fast the pipefish grew. The researchers used different waters (Portugal and Ireland) and the different temperatures of waters. That way it gave them more information to learn and choose from. Their hypothesis stated that the southern pipefish population would sense warm water and a longer breeding time, across a milder pressure of selection, with fewer females. The researches had predicted that the fish living farther north are where the males will be necessary, that...

...COOKIES CHAPTER 3 METHODOLOGY This chapter presents a discussion of the research design that comprises the sampling design, population sample, ingredients, materials, procedure, data gathering instruments and statistical treatment of data. Research Design The single-group research design will be used in this study to determine the acceptability of Nostoc as an additive in making cookies. There will be three (3) treatments. The independent variable in the study will be the amount of Nosotc incorporated in the plain cookie. The dependent variables are the taste, appearance and aroma of the Nostoc cookie. Ingredients 100 grams butter 125 grams of plain flour 50 grams caster sugar 1/2 teaspoon salt 60 grams brown sugar 1/2 teaspoon bicarbonate of soda 1 large egg At least 200 grams of dried Nostoc 1/2 teaspoon vanilla essence/extract Material and Tools Baking tray Whisk Bowls Table spoon (preferably) Procedure 1. Turn your oven on to preheat at 180 degrees Celsius (about 350 degrees Fahrenheit, gas mark 4). Remember to take your grill pan out first. Now get some baking trays ready (if they're not non-stick then you better line them or grease them). 2. In a big bowl add the butter and both sugars, and then beat them until they are light and fluffy. A whisk would be needed. You'll know you're pretty much there when the color starts to lighten, and the sugar starts to look less granular. 3. Add egg and vanilla essence and mix them all together well. 4. In a separate...

...DK Publishing. The book describes the sponge cake as a “Versatile sponge that goes well with a number of filling. This version uses buttercream and lemon curd for a zingy tartness to balance the vanilla.”. In the past I had made buttercream but I failed and ended up tasting horribly but this was the first time I had made frosting and a lemon curd from scratch and had been successful. Although the recipe did not have instructions on how to make the lemon curd it was a simple process of lemon juice, an egg, granulated sugar, a stick of butter and lemon zest over a simmer of 6 minutes in a small pot and an extra 20-30 minutes in the fridge for the curd to cool down. As soon as that was finished I moved onto my vanilla sponge cake. I grabbed all my ingredients that consisted of eggs, granulated sugar, vanilla extract, self rising flour, butter and confectioners sugar. I sifted in my sugar and added my eggs and beat it with an electric mixer for about 5 minutes then added a few drops of vanilla extract. I sifted in the flour and completed mixing everything together. I buttered my pan and put it in the oven for 30 minutes. When it was done baking I had realized that the mix did no rise like I thought it would, later while reading “Everyday Easy Cakes & Cupcakes” by DK Publishing, it states that self rising flour and regular flour are very different from each other. To make your own self rising flour you mix 1 cup of all purpose flour, with one teaspoon of baking powder, and ¼ teaspoon...

...precedent by introducing genetic changes that pass down to future generations. The ethical issues raised by the procedure are clear but for many doctors these are overridden by the chance to prevent life-threatening disease. The best that doctors can do today is reduce the risk of children being born with mitochondrial disease. Specialist clinics already offer chorionic villus sampling (CVS) at around 11 wekks into pregnancy, which can pick up genetic abnormalities. Some women who carry mtDNA mutations opt for IVF. That way, doctors can use a technique called preimplantation genetic diagnosis to select embryos that are free of the disease. In Newcastle University, Turnbull, a professor of neurology and director of a center for mitochondrial research, is working on ways to eliminate the risk of disease by replacing the mother’s faulty mitochondrial wholesale withthose from a healthy donor.

...course of this presentation, we will see the personal health advantages of becoming a vegetarian, our ability to prevent animal cruelty, and the benefits to the environment and the world. Impact of the Topic and Speech: I hope that my speech will give you some thoughts to think and questions to ask. So if you have any, you may ask them after my talk. Transition: First, let’s examine the health benefits of becoming a vegetarian [BODY] I. Becoming a vegetarian has substantial health benefits. HEART DISEASE RISK Vegetarians have a lower chance of developing heart disease than meat-eaters, according to a study published in the journal "Public Health Nutrition." This large-scale study was undertaken by researchers of the Imperial Cancer Research Fund in Oxford, England, and studied a total of 76,172 women and men living in the United Kingdom, United States and Germany. Overall, vegetarians were found to have a 24 percent lower risk of dying from ischemic heart disease than those who ate meat OBESITY According to Mayo Clinic dietitian Katherine Zeratsky, “On average, people who follow a vegetarian diet eat fewer calories and less fat than nonvegetarians. Vegetarians also tend to have lower body weight than non-vegetarians.” As you can see, vegetarians have much less chances of...

...With knowledge of over 100 species, these diverse creatures are adept swimmers with ten appendages. (NCBI, Intro). Two of which are for feeding and respiration, another two antennae. Female Daphnia organisms have an visible reproductive organ, the egg sac. If looked upon with a microscope, eggs can sometimes be seen inside of the organ. They inhabit bodies of freshwater, excluding those with extreme climates. (NCBI, Intro). These animals are known for filter feeding, but will occasionally attach to water plants. Commonly called a water flea, this animal is largely unnoticed because of its small size. The daphnia is preyed upon by fish and other creatures of larger size. (NCBI, Intro). This crustacean can range from a size smaller than a half millimeter to six millimeters. (NCBI, Intro). This small size allows for chemicals to quickly take effect, making the Daphnia an optimal creature for experimentation. Furthermore, these animals are transparent, allowing for easy observation of the organs and insides. The...
