Guys, its past due, please help me!! Part One: Defining the Problem and Sub-Problems

1. Choose one of the real-world problems about natural resources to research. Explain which one you chose here.

2. Research this problem to learn more about it. Use the research tools given in the lesson if you need help.

3. After you have researched the problem, explain in your own words who the problem impacts and why it is important.

4. List two sub-problems that are part of the bigger problem but are more manageable and solvable.

5. Explain how these sub-problems are related to or a direct result of the overall problem.

Part Two: Criteria, Constraints, and Prioritizations

1. Choose one sub-problem that you will investigate further and explain which one you chose here.

2. List two realistic criteria for the sub-problem.

3. Explain why it is important for these criteria to be met in order to solve the problem.

4. List two constraints for the sub-problem.

5. Explain why these constraints exist. (How do they limit solutions to the problem?)

6. Prioritization of the criteria and constraints and an explanation supporting the decisions made based on research.

Ranking | Criteria or Constraint | Reason for Prioritization

Part Three: Generate Solutions

1. List two solutions that you have generated for the chosen sub-problem.

2. Describe how the sub-problem can be solved, and include the research supporting each solution.

3. Explain how prioritization was involved in designing each solution.

4. Explain how both solutions to the sub-problem play a role in solving the larger problem.

5. List of the sources (at least three) you used for research, following the MLA style guide.

according to the u.s. department of agriculture, the label of "certified organic" comes with a set of highly regulated standards for environmental stewardship and resource conservation. some of these include maintenance and improvement of soil quality, prevention of ground and surface water contamination, greenhouse gas regulation, encouragement of biodiversity and conservation of water and energy (see references 1). organic practices integrate natural methods such as mulching, plant diversity, native and adapted plants, crop rotation and the introduction of beneficial insects to control pests without synthetic pesticides.

environmental implications of pesticides

synthetic pesticides ensure high crop yields. while effective in achieving this goal, pesticides contaminate soil, air, ground and surface water, as well as the plants and animals that come into contact with these contaminated sources. freshwater and marine organisms are particularly susceptible to pesticides through agricultural runoff. pesticides also reduce soil fertility (necessitating the use of synthetic fertilizers) and can travel far from the original source, contaminating water and air hundreds of miles from the location of application (see references 2).

health implications of organics

although a subject of particular debate, many recent findings show that organic food is healthier than conventionally grown food. according to the usda, an extensive european union-funded study found that organically grown foods contain more beneficial compounds, such as the vitamins and antioxidants needed to combat many diseases (see references 5). organic milk, meat and eggs are regulated to ensure they are free of hormones administered to conventional livestock and poultry.

health implications of pesticides

pesticides affect human health in three ways: through skin contact, inhalation and ingestion. acute and long-term exposure to pesticides can cause serious health problems for farmers who apply them. the majority of other people are affected by drinking contaminated water and eating contaminated marine life (see references 3). pesticides have been linked to neurological disorders, endocrine and reproductive disorders, immune system deficiencies and cancer. according to the world health organization, acute pesticide poisoning (app) is responsible for significant annual mortality, especially in developing nations (see references 4).

other important considerations

not every small farm or business owner can afford the costly certification process required to be considered "certified organic," even if the farm is not using chemicals. "transitional" farms include those that once used chemicals and are now transitioning to organic-only production. in addition, though organic farming methods offer obvious environmental benefit, an organic apple shipped from around the world creates a different set of environmental problems. locally grown food (particularly locally grown, organic food) is key in sustainable food production.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
