Developing and Selecting Solutions Graham Parker’s Structured Problem Solving Guide describes the problem solving process in four phases, one of which is Developing and Selecting Solutions (Phase 4). The other phases are not summarized here, however, it is noteworthy to mention that Phase 4 is the entering into solution development, whereas during the first three Phases of the process, specific problems of study have already been defined, a selection process is undertaken to decide which problems
Solutions to Global Warming Scientists report that global warming has been escalating since the Industrial Revolution. Governments are trying to reduce carbon-dioxide emissions. With the speed of destruction of Earth?fs ecosystem, the survival of many species, including human beings, is threatened. In order to solve this danger, we have to reduce the consumption of energy and use the alternative energy resources. If we calculate the present energy price, alternative energy must be more expensive
Solutions to Juvenile Crime Crime is a plague that has haunted American citizens for centuries. The severity of crime has ranged from running a red light to cold blooded murder. Statistics indicate that crime rates have been on the rise in the previous decades, especially juvenile crime. Statistics show that, ‘the number of youths aged 14 and younger who have been charged with homicide has jumped by 43 percent in the past twenty years’ (Kids With No Hope, No Fear, No Rules, And No Life, 2).
Osmosis is the movement of water molecules from an area of high concentration; (a weak solution), to an area of low concentration; (a strong solution), through a partially permeable membrane. My experiment will prove that the concentration inside the potato is lower than the concentration of the water molecules, outside the potato if using distilled water or very low concentrations of sucrose solution. Preliminary Method Cut two potato cylinders to the correct sizes e.g. 5cm in length
KPMG Three Little Pigs Inc. Solution Several factors including increased supply have caused declining prices for live hogs on the spot market. Also as shown below, futures prices will remain below the carrying cost for live hogs until nearly the end of the fiscal year. However, processed pork products such as bacon, loins, and ham remain above the current cost of production. Three Little Pigs Inc. is capable of processing hogs into these products internally at some locations. Unfortunately,
The Band-Aid Approach- Not the Best Solution The band-aid approach has been the most common solution to working with students at risk. The name for this approach comes from the purpose of a band-aid; to cover up a problem but not fix it. A problem with this resolution is only having half-day sessions focusing on one topic for these students. This is not helping in the end because for the other half of the day, when they are in their regular classroom settings, this type of attention and teaching
Solutions to the Air Pollution Problem in America It is steadily becoming harder to breathe these days. Every major city in the world is experiencing the ill effects of air pollution. The level of toxic air pollutants, known as toxics, has been on the rise globally, though not nationally, since the Clean Air Act of 1990, according to Office of Air Quality Planning and Standards [OAQPS], an office within the Environmental Protection Agency [EPA]. However, though more regions -- i.e., cities
Buddhism is the Solution to Our Current Environmental Problems The destruction of the environment is a major problem in the world today. The exploitation of natural resources, over population, pollution and the spread of human’s impact has negatively affected the quality of the Earth. All life is suffering from the environmental degradation. Air and water quality in cities and surrounding areas is poor. Greenhouse gas emissions are causing a global climate change that is displacing many species
1. Compare the different groups who drank 7.5ml of fluid for each kg of body weight. Which group had the highest average urine production rate? Why? o The group with the highest average urine production rate of 7.5 mL of fluid for each kg of body weight was the diet caffeine free group. Diet caffeine free uses NutraSweet instead of glucose as the sweetening agent. NutraSweet causes high filtrate osmolality, which decreases reabsorption and moves water from out of the tissue into the urine, increasing
calculated in Equation 2. Both equations were able to be used given that the measurements were in terms of molality, which is not temperature dependent. After completing calculations, the average Kf of the three trials of the p-xylene and toluene solution was computed as as 4.56(C/m) as shown in Table 1, however, the theoretical value was slightly lower than calculated, 4.3(C/m). This resulted in a 6.04% error as shown in Equation 5. Possible causes of error could have resulted from adding too much
She does not single out children or make accusations, even when she is told that one child pushed another child out of the way. The next step is determining what the conflict is about and conveying that each child will be able to help find the solution. The educator facilitates this by asking the children for details about the conflict. She asks “What happened? And then what happened? Which side were you holding?” The educator allows each child to tell their version of what happened, and
Injectable Hydrogels: Processing and Application Introduction Hydrogels are defined as networks made up of polymer chains which are hydrophilic. They are in some cases found as a solid dispersed in a liquid. where water acts as the medium dispersed. Hydrogels are natural, highly porous or artificial polymeric networks. The hydrophilic structure allows hydrogels to hold the significant amount of water within their three-dimension structural systems. The extensive employment of hydrogel products in
Solutions for Homelessness This great nation of awesome power and abundant resources is losing the battle against homelessness. The casualties can be seen on the street corners of every city in American holding an ?I will work for food? sign. Homeless shelters and rescue missions are at full capacity. There is no room at the inn for the nation?s indigent. Anyone who has studied this issue understands that homelessness is a complex problem. Communities continue to struggle with this socio-economic
Solutions to Poverty Poverty is a major problem in the United States today. Social, economical, political, and cultural factors all contribute to poverty. Education and economic development are two major issues that will help prevent poverty. The United States Census Bureau defines poverty as an "economic condition in which people lack sufficient income to obtain basic needs for food, housing, clothing, health services and education." In other words, poverty is powerlessness, a lack of representation
Finding the Water Potential of Potato Cells Aim: Our aim was to discover the water potential of potatoes cells using different concentrations of sucrose solution Science: Osmosis is 'the movement of water molecules from a region of higher water potential to a region of lower water potential through a semi-permeable membrane' www.s-cool.co.uk 'Water can move between cells (unligninified) freely as the cell walls are permeable. However its movement is controlled by a number of factors
to cut the potato I have a white tile underneath. The experiment will be a fair test as I will keep the weight of the cut potato the same throughout the water and sugar solutions. I will try to keep the potatoes surface area and volume the same. I will make sure that both pieces of potato are placed in their solutions at the same time and pulled out together. I will make the weight of the potatoes the same by using the top pan balance and keeping the weight roughly the same through out
different molar solutions of sucrose and water. Apparatus: -Cutting tile which will be used to cut the potato on. -Knife which will be used to peel the potato with and to cut to correct mass. -Burette which will be used to measure the solutions acurately. -Distilled water to make up solutions as part of the experiment sucrose to make up part of the experiment -Potatoes to cut into equal mass and observe what happens to them when left in differing concentrations of sucrose solution. -Tissue
when the most concentrated solution is used the reaction would be at its fastest. Collision Theory: In a more concentrated solution there are more particles so collisions occur more frequently. The more often they collide the faster they react. This means that the rate of reaction will increase if the concentration of the reactants is increased. As shown below: Key= Sodium Thiosulphate Hydrochloric Acid Less concentrated solution More concentrated solution Independent Variable

The definition of buoyancy is “the ability or tendency to float in water, air or some other fluid”. Buoyancy It tells you about the ability of an object to float on the water or liquid. You can determine whether an object will float or sink, not by checking the relation between the weight of the water and the weight of the object. People use buoyancy all the time, it is used to create a water object. Such as boating and scuba diving. If you think about it like this when you are on the top of the
