Project Design Plan

There are many times and reasons when a person wants a cold drink, but sometimes a cold drink is

nowhere to be found. When this happens, you are presented with the option of drinking your drink

at room temperature, or finding a solution to cool it down in a timely manner. Most people resort to

throwing their drink in the freezer for a half an hour or so in order to cool it to an acceptable level.

However, is that the best and most efficient method of cooling a drink down quickly? Is it even more

efficient than putting it in the refrigerator? I intend to test to find out.


I suspect that the refrigerator and freezer are not the most efficient ways to quickly cool a drink. Both

the refrigerator and freezer cool through convection, and I believe conduction will prove to be a more

effective cooling method. As such, I will test both the refridgerator and freezer, as well as several

variations of ice baths.I believe that an ice/water/salt bath will provide the best results, because it will

provide for the most conductive area, and will also have the lowest conductive agent temperature,

because the addition of salt will lower the freezing point of the ice/water solution, allowing the solution

to get a few degrees colder than the standard ice/water solution.

Experimental Design:

To test the above questions, I intend to test a solution (in this case, simple bottled water) in a variety

of different environments to see which environment cools it the fastest. I will test 5 different methods

of cooling the bottles of water, and I will test 4 bottles in each method at different timeframes. The

1. Bottled water in the refrigerator with normal use. I will put bottles in the refrigerator, and will

remove them at the designated testing time periods. During this time, the…...

Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Characteristics of tundra include: 1. Extremely cold climate 2. Low biotic diversity 3. Simple vegetation structure 4. Limitation of drainage 5. Short season of growth and reproduction 6. Energy and nutrients in the form of dead organic material 7. Large population oscillations Tundra is separated into two types: Arctic tundra Alpine tundra Tundra along the Colville River, Alaska. Arctic tundra From left: tundra near Churchill, Manitoba, Canada; tundra in the Arctic National Wildlife Refuge, Alaska. Arctic tundra is located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga. The arctic is known for its cold, desert-like conditions. The growing season ranges from 50 to 60 days. The average winter temperature is -34° C (-30° F), but the average summer temperature is 3-12° C (37-54° F) which enables this biome to sustain life. Rainfall may vary in different regions of the arctic. Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches). Soil is formed slowly. A layer of permanently frozen subsoil called permafrost exists, consisting mostly of gravel and finer material. When water......

...INT1 Task 3 Page 2 Project Design Plan This experiment asks the question, “What paper towel is more absorbent for the price per sheet?” Will the more costly paper towels absorb a bigger spill therefore giving the consumer reasoning on buying the higher priced paper towel? This experiment will examine the absorbency of three different brands of paper towels and then compare the results to the price of the product to find the absorbency value. First, we will purchase one roll from three different brands of paper towels from the same store at retail price. It’s important to purchase the products at full cost or note what the normal price is from the same store since different stores may have different prices. Different brands of paper towel rolls come with different amounts of sheets as well as sizes, so it will be important to have all the sample sizes the same for accurate results. The results will be drawn up after the controlled experiment is finished. The experiment will consist of taking an individual sheet from each brand of paper towel and spread it over a container and using a medicine dropper or eye dropper filled with water, squeeze drops onto the paper towel one at a time until the water starts to leak into the container below. Each drop will be counted up to the point where the water leaks into the container. This will be done three times with each......

... and moisture (Lawson, 2001). However, literature indicates that mealworms are unlike most organisms as they are the second phase of development of the beetle. The beetle is an insect with grows and develops in four stages to reach complete metamorphosis from egg, larva, pupa, and adult (Schaffer, 2003). This research carries out a scientific experiment to identify the growth rate of the yellow mealworm, Tenebrio Molitor. The goal of the experiment will be to map out the rate of development of the beetle in its second life cycle in different conditions. The research will try to solve the following research questions: 1. What is the rate of growth of mealworms? 2. To what extent does temperature affect the rate of growth of mealworms? 3. To what extent does light, affect the rate of growth of mealworms? Relevance of Testable Question The research questions identified assist in identifying the research variables that will be tested. They also define the scope and extent of the study and determine the extent of the scientific research. Therefore, from the research questions the variables are rate of growth, temperature, time, and light. Literature Review Mealworms are the second stage of development of insects whose growth and development is in four stages of development, this is egg, larva, pupa, and adult. A review of literature indicates that insects in the same species with the mealworms have their four stages active both day and night. However, for the......

...INT Task 3 Does Salt make Ice melt Faster? Project Plan Salt is known to be used on icy roads in certain areas of the country in the winter season to help clear roadways to make them safer for travel. Salt causes a reaction that lowers the freezing point of water. In this experiment we will test this method of applying salt to ice to see if for certain this is true, and how much faster the salt melts if so. In this experiment, the Independent Variable will be adding Salt to the ice and the Dependent variable will be the time it takes the ice to melt. The Plan is to use two ice cubes in separate containers, and add ice to only one of these. Each will be timed and observed for the duration it takes both to melt, and data will be collected throughout. At the end of the experiment, enough information will be gathered to confirm whether adding salt to ice in turn makes it melt faster, and how much faster this occurs versus adding nothing to ice. This will prove or disprove the benefit of using salt on roads to help make ice melt faster. Literature Review Many experiments have been done to test what makes Ice melt faster. Some of these included one or many different additives such as: Table Salt, Sugar, Pepper, Rock Salt. In these studies Salt prevailed as the one ingredient that would speed the melting time of Ice significantly versus adding nothing, or another substance such as sugar. (Nina DeSales, 2014). In one study Salt was added to ice water. This was done to......

...INT1 Task 3 Example Does More Sugar Make Lemon Sauce Runny? By N. Shane Cutler Project Design Plan Cornstarch is a common thickening agent in cooking. Plant starch is made of a mixture of amylose and amylopectin. When heated in a water-based solution, the starch molecules can unwind and then form new hydrogen bonds with other starch molecules, making a network of long molecular filaments that can hold water molecules in a gel (Holmes, 2012). The Argo Cornstarch website warns that too much sugar can interfere with thickening (Argo, 2012). Literature Review There are many different ways to thicken liquids and thickening liquids has many applications. Many experiments have been done to test different thickening methods. GVSoapCo tested 4 different substances to thicken homemade liquid hand soap: Xanthan Gum, Borax, Salt or Crothix. This experiment used the same soap recipe, substituting the different thickening agents. The experimenter then tested the thickness or runniness of the finished soap by spooning it up and drizzling it. This showed that the Crothix thickener made the thickest, smoothest soap, whereas the salt made the thinnest, runniest soap. While the spooning method was effective at showing the qualitative difference the thickening agent made, it didn’t produce quantitative measurements of the relative thickness (GVSoapCo, 2013). Foy compared low sugar pectin with traditional pectin in making grape jelly. She reported that the traditional pectin made firmer jelly......

...Integrated Natural Science (INT1) Task 1 The Changing Nature Of Science Evolution Evolution :- All living beings have developed over time from ancestors through a series of changes. That life has changed over long periods of time, with all forms of life related to one another, is a scientifically well-established fact. There are two aspects of evolution today. First, evolution is the organizing principle for all of biology. Just as we are offspring from our parents, and our grandparents before them, and so on, all living organisms today are inclined from organisms that lived in the past. Understanding how and why these ancestor-descendent lineages have changed through time helps us appreciate the diversity of life we see today. Genetics, anatomy, physiology, neurology, morphology, and behavior all of these aspects of living organisms have evolved through time. The study of the evolutionary processes that produced these traits provides the comprehensive framework for understanding them. Theory Of Evolution Evolution Theory: - Evolution is technically defined as: "a gradual process in which something changes into a different and usually more complex or better form." As it is most famously used, "evolution" is the process by which an organism becomes more sophisticated over time and in response to its environment. The Theory of Evolution is currently the most popular concept of how life reached its current state. Evolution as a biological mechanism is driven by natural...

...INT1 Task 3 Do more expensive paper towels absorb more water than less expensive products? By: Gregory M. Herrin Project design Plan When consumers are in the store to purchase paper towels, there are numerous options and brands to choose from; all claiming to be the best product with the most absorbency. How does a consumer choose the best option for the best price? The goal of this experiment will be to determine if higher priced paper towels are more absorbent than the less expensive paper towels on the market. Four relatively common brands will be tested for their water absorbency: Viva ($0.049/square foot), Bounty ($0.046/square foot), Brawny ($0.044/square foot) and Sparkle ($0.024/square foot). Ultimately, the experiment should show which of the commonly used household paper towels is more water absorbent and if price equals value for these products. Literature Review A number of experiments have been completed to demonstrate and/or test the absorbency of paper towels. Len Penzo dot Com, a personal finance blog, completed an experiment on which brand of paper towel was the best value. They tested six different brands of paper towels for absorbency and scrub strength: Sparkle, Bounty, Bounty Basic, Scott, Shoppers Value, Viva and Kirkland Signature. To measure the absorbency, the paper towels were dipped into glasses of water until saturated and then the water squeezed from the towels was measured. To measure the scrub strength, the towels were......

...INT1 Task 3 Does the salinity of water effect the amount of time it takes to boil? Project Design Plan The normal boiling point of water is 100°C (Bodner research Web, n.d.). Salt is considered to be a non-volatile soluble substance and in turn is supposed to increase the temperature at which the water boils Southwest Research institute, 2014). Chefs have thought for ages that adding salt to water would increase the boiling time. A higher boiling temperature should increase boiling times although displacing water with salt reduces the volume of water to boil. Literature Review The boiling point of a liquid is the point at which the liquid transition to a gas. Once the boiling point is reached the temperature remains constant until all of the liquid has changed state to a gas (Bodner Research Web, n.d). Salt water has a higher boiling point than plain water. It takes less energy to increase the temperature of salt water by 1°C than it does for regular water. The heat capacity of dissolved salt is almost zero so displacing regular water with salt water lowers the amount of time to heat the same capacities of water because of the displaced water volume by the salt (Southwest Research Institute, 2014). There have been many experiments on the subject of salt water and boiling times. Typically these experiments have been incorrectly done as simply adding salt to identical volumes of water has almost zero effect on the boiling times or temperature. The correct way......

...INT1 Task 1 Western Governors University We all easily recognize beer and wine and many of us consume these products in a responsible manner. What most people don’t recognize is the science that goes into the making of adult, alcoholic beverages and the history of the ‘behind the scenes’ science that goes into making these products. Scientific knowledge grows at an exponential rate, and nowhere is this more evident than in the historical milestones of chemistry and biology that have shaped our understanding of the microorganisms that cause fermentation. The most important microorganism involved in brewing is yeast and yeast has been integral to pioneering work in the fields of metabolism and eznymology (Chambers & Pretorius, 2010). What we’ve learned and now understand about yeast: For several millennia man has used yeast for baking bread and making alcoholic beverages although before the microscope these people did not understand what yeast was or why it worked. In 1857 Louis Pasteur proved that fermentation was cause by living organisms, in this case the organisms were yeast ( Through Pasteur proving that yeast was a living organism mankind began to understand the carbon dioxide emitted by the yeast caused dough to rise. Pasteur proved that chemical reactions of yeast and sugar caused the formation of alcohol ( Through genetic modification, yeast used to make wine can now be engineered......
