Need a good experiment idea for the assignment below. I have all the beakers etc. yeast, random household products, and fruits.Trying to come up with a good simple experiment that doesn’t involve the yeast/balloon/hydrogen peroxide we already did. Thank you!

Final Applied Lab Project (1 credit Lab Component)

 Addresses course outcomes 1-4:

• recognize and explain how the scientific method is used to solve problems
• make observations and discriminate between scientific and pseudoscientific explanations
• weigh evidence and make decisions based on strengths and limitations of scientific knowledge and the scientific method
• use knowledge of biological principles, the scientific method, and appropriate technologies to ask relevant questions, develop hypotheses, design and conduct experiments, interpret results, and draw conclusions

This is the culminating lab assessment in BIOL 103. It is designed to assess your ability to apply the principles of the scientific method.

The Effect of low pH on Enzyme Activity

Design an experiment in which you will test the effect of an acidic fluid on enzymatic activity. Recall: enzymes are proteins! To complete this project, it may be useful for you to first review the Scientific Method Tutorial, information about pH and enzymes in the text book and course modules, Lab 1 (Introduction to Science) and Lab 4 (Enzymes). As you review Lab 4, you will be reminded that there are several factors that impact enzymatic activity: pH, temperature, and amount of reagent. It is OK to use the same enzyme/substrate/method as you did in lab 4 (but modify the treatment), or you can search on-line to find a different enzyme/substrate/method for measuring enzyme activity for your project (include all references).

As you design your experiment for this project, please remember that you are trying to examine how an acidic fluid will modify the outcome of an enzymatic reaction. To successfully complete this project, you will need to identify the question(s) being asked in your experiment and the hypothesis that you are testing. In your experimental design, you must clearly explain what you are doing. That means that you will need to identify the enzyme, the substrate, the acidic fluid used as treatment, the control treatment and the method of measuring enzyme activity, as well as explain your experimental protocol. You must also thoroughly explain how the acidic fluid impacted enzyme activity based on the results from your own experiment as well as knowledge of enzymes and pH from the text book, modules, lab manual and potentially additional information sources.

Hint: Keep in mind that the acid will change the environmental conditions of the experiment (for example, a low pH value could change the shape of the active site on the enzyme protein), without directly participating in the reaction.

Lab Materials

You may need all or some of the following, depending on your experimental design:

Materials from your lab kit:

• pH paper
• hydrogen peroxide solution (you can purchase this at a pharmacy if you have used up the bottle that came with the lab kit)
• plastic beakers or cups
• vinegar
• yeast (can be purchased at grocery store if more is needed)
• balloons
• plastic bottle
• marker for labeling of beakers
• Cell phone/digital camera – pictures required

You may choose to use additional materials (different acidic fluids and/or different organisms and/or different substrate if you chose an enzyme other than catalase).

Outline:

Include the following in your outline:

• Name of enzyme you will use
• Name of organism (if applicable)
• The substrate and products in the chemical reaction
• Method for measuring enzyme activity
• Treatment: acidic fluid(s), pH, length of exposure, how you will treat your samples
• The control(s) in the experiment
• Hypothesis
• How you will present your data (table and/or type of graph)
• Anything else you would like to get feedback on before you start your experiment

Write a lab report that includes the following:

1. Title page: descriptive title, your name, course name, semester

2. Introduction: general background information about enzymes and specific information about your chosen enzyme, the question(s) that you are asking and a clear hypothesis for your experiment (20 points).

3. Design an experiment. Provide a detailed description of the materials and methods used to conduct the experiment. Identify control and experimental samples, as well as independent and dependent variables. Also include the methods used for data collection and analysis (20 points).

4. Conduct the experiment and record your results. Take picture of results. What did you observe? Present your data in table and/or graph format. Remember to label everything and include the unit of measure with all numbers (20 points)

5. Use your knowledge of enzymes and pH to interpret and discuss your results. It may be necessary for you to refer to the text book and course modules, lab manual and/or use additional information resources. What effect does the acidic treatment have on enzyme activity? Did you get the expected results? Explain. (20 points)

6. State a specific and accurate conclusion. Is your hypothesis supported by the results? Looking back, how could you have improved your experiment? (10 points)

7. Include a list of references to all information sources used in APA format (5 points).

I need help getting started. I have an ongoing project and need to get the foundation laid out. In order to get started I need to come up with a Database Design. During my course I am supposed to be designing and developing a database that can be used to compile and report clinical data related to either quality measures or pharmaceutical products and utilization. The proposal is the initial step of this assignment.

For the proposal, I need to come up with…..

1. Statement of the project problem and definition of terms.
2. Identify your users (personnel/credentials): Who are they? What are their competencies?
3. Discuss the information data users need to compile for the proposed system and the types of reports the proposed system should be able to generate and why.
4. Based on your response to #3, articulate the project goals and objectives for the database design and how they affect the data model.
5. Identify the steps you will take to meet the goals and objectives.
6. Forecast any potential problems or barriers to meeting the project goals and objectives. Are there any specific assumptions that need to be made?
7. Conclude with the value of the project with emphasis on feasibility, necessity, usefulness, and the benefit of the expected results.

Any help would be appreciated!

I have an exam in marketing.The exam will be about analysis case studies. The professor will give us a case study and we have to analyze it ( identifying the problem ,finding alternatives,evaluating the alternatives, and writing recommendations) I don’t know how I should start studying and preparing. Does anyone can guide me to the correct way to study or give me an excellent source that explains how to analyze a case study step by step? 

Thank you,
