choose a science of cooking experiment and follow guidelines for experiment.will provide guidlines and all textbook resources needed. the assignment is the unit 4 lab word document if you scroll all the way down.there are examples of experiments to do

Instructions for Discussion Board Lab Report Post:

1. Introduction and hypothesis with rationale (5pts):

Write a few sentences introducing the basics of your experiment with a focus on why you are doing it, what you expect to see as you carry out the experiment, and your rationale for why you think you will obtain those results. In particular, you will need to let us know what question you are hoping to answer in doing your experiment. Your best guess of the answer to this question is known as the hypothesis of your experiment. A hypothesis is a statement of what you think will happen in an experiment. It should be specific, testable, and backed up by what you have learned. This is your educated guess of what you think the experiment or activity will produce or show. For example, your hypothesis might state what the difference will be between two types of cheese based on your readings, or how you expect your homemade yogurt to taste/feel/look like. Remember that this is scientific, so should be focused on measurable things that you can test in the experiment. Things like “I think sweet cream butter will taste better than margarine” is an opinion, and not repeatable or scientific so will receive minimal points. Something like “I think sweat cream butter will be more solid and less spreadable than margarine” or “I think sweet cream butter will melt faster than margarine” are more scientific and testable.

1. Experimental design and methods (8pts):

Design your experiment and write a paragraph or two detailing specifically what you tested or carried out and why you chose specific measurements to test your hypothesis . Remember that your experimental design should be repeatable. You will need to explain what you did to try to control the variables so that if you notice differences or changes you can determine what caused them. This should include specifics on the choices you made for tastings, details on exactly what you were evaluating/measuring, the procedure you used for collecting the data, or the specifics on the procedure for the activity you carried out (what did you do and why). You should make sure someone else could replicate your experiment exactly by including things like brand names, amounts, rating scales, and types of equipment or tools used.

1. Results (10pts):

Present your findings. Show us what you observed/measured/etc in order to test your hypothesis or answer your experimental question. All of the data you collected for your experiment should be presented here. Data tables are a very useful way to organize your data and observations. A table of rankings or measurements or observations over time is expected. Organizing your results into a graph may be useful. You may need to do some calculations to determine the average (and error) of your measurements. Images are always helpful and useful in supporting your observations.

You will need to include at least one picture of your set-up and/or results. Make sure one included picture of your set up or results has your name card in it! If you do not include any pictures you will automatically lose half the credit for the assignment.

1. Analysis and Discussion (8 pts):

Summarize your results and tell us what you think they mean. What conclusions can we draw from your experiment? Discuss in a paragraph or two how what you saw relates to what you have learned in class and explain the science behind what you observed in your results. Did your results support your hypothesis? Suggest a scientific reason why your results may or may not have supported your initial predictions. Explain why there were differences between your samples or what scientific principles were responsible for the observations you made as you completed the activity. Discuss what you could do in the future to add to your results and gain additional information.

1. Comment on two other student’s posts (4pts):

You will need to comment on at least two posts of other students for this unit. Your comments should have substance and show your understanding of the course material to receive full points. Please keep all comments respectful and constructive. Disrespectful or degrading comments will be removed and will receive no points. Please be part of the discussion by responding to posts on your own experiment.

Examples of substantive contributions may include (but are not limited to):

· You could compare the poster’s experiment to your own results and suggest reasons for similarities/differences.

· You could suggest further experiments or tests that could be done and discuss what additional insights they might provide.

· You could add thoughtful commentary or additional insights to the poster’s analysis.

**Reminder: If you do not include a picture of your set up with a name card in the frame you will automatically lose half the credit for the assignment.**

Example Experimental Ideas:

1. Slowly heat and melt different types of cheeses

· Review pages 64-66 for hypothesis ideas

2. Compare the physical properties and taste of different types of cheeses

· Review pages 55-62 for hypothesis ideas

3. Make your own simple, acid-curdled cheese.
