Hypothesis:
Explain how temperature and volume of a gas are related and use that to make a prediction about how you can use this information to calculate absolute zero.
Procedure:
Access the virtual lab and complete the two trials of the experiment simultaneously. List your controlled variables, independent variable, and dependent variable. Explain why these are the variables. Summarize the steps of the experimental procedure.
Investigate the effect of increasing concentration of hydrochloric acid on the rate of reaction in the reaction between hydrochloric acid and marble chips.
Question 1
Do you suspect nutrients such as vitamins and minerals could induce, aggregate, and/or possibly prevent the misfolding of proteins?
Question 2
Vegans must combine amino acids from different sources to form a complete protein, do all the essential amino acids need to be eaten at once or can a ‘complete protein’ be comprised of different meals throughout the day?
Wondering if the body needs to have all the essential amino acids available at once in a meal (like what eating meat would provide) or if eating enough of all the needed amino acids throughout the day (but not all at once) would work?
What is science? More specifically, what makes something science? How is science distinguished from non-science or pseudoscience?
These questions have been the source of debate for many centuries, even millennia. Two thousand years ago, natural philosophers disputed the very nature of matter. Was matter continuous, infinite, and divisible as claimed by Plato, Aristotle, and their contemporaries? Or was matter discontinuous, finite, and indivisible, so that a certain smallest, most fundamental unit could be attained, as claimed by Leucippus, Democritus, and few others. Over 2000 years ago, Leucippus coined a term for this fundamental and smallest unit of matter – atomos, yet these ideas were largely ignored for millennia.
As listed in our text, the main steps of the process are: Observation, Hypothesis, Experiments, and coming to a Conclusion whether your hypothesis has been verified or disprovem.
The idea of the scientific method requires that claims are:
Falsifiable (refutable – able to be disproved) and Repeatable.
These are often the criteria used to help distinguish science from pseudoscience. The falsifiable nature of science dictates that the claim must be able to be disproved. We also note that science is a process of discovery, and part of that process of discovery requires the recognition of patterns (repeatability).
Note that in science, evidence may strongly suggest that a claim is true, but it does not explicitly prove it.
An example of a falsifiable claim is that the moon is made out of cheese. As silly as the claim is, we could gather a sample of the moon and – if it is not cheese – we have disproved the claim. Thus, the claim is scientific because it may be disproved through collection of evidence (data). Furthermore, the moon could be sampled repeatedly and we would still arrive at the same conclusion – the moon is not made out of cheese. A non-scientific claim cannot be disproved regardless of the evidence collected. For example, if I claim that a cubic meter of cheese exists on the moon, I have made a non-falsifiable claim because the claim cannot be readily refuted. It would be nearly impossible to sample every cubic meter of the moon, and thus the claim is not scientific.
Throughout this course you will be applying the scientific method in your laboratory work, and just as important as the above concepts, will be practicing lab safety techniques. Our Lab 1: Laboratory Safety goes over the very important lab safety procedures that you will want to adhere to throughout this course. In Lab 1 you will learn about many safety rules including: wearing the appropriate clothing, preventing contamination of your samples, wearing safety gear and handling chemicals appropriately, etc…

Make sure to come up with a unique short Subject heading that describes your post and then you can return and reply to your post with your summary. Within your summary please construct a well-thought out response that addresses each of the following questions.
What makes one statement or claim science? Along these lines, how do you distinguish a scientific claim from a non-scientific claim, or pseudoscience?
Construct a claim that you consider scientific and indicate how the claim meets the criteria for science – that it is falsifiable and repeatable. Challenge your peers to either agree or disagree with the scientific nature of your claim.
After reading through Lab 1, pick a safety rule that was covered and write a few sentences explaining how you will apply that rule in your lab work.
Be sure to state any references you used along with proper citations.
OVERVIEW:
No matter where you look these days one can’t help but notice how many different diets there are mentioned in the news and different forms of media. Many of us because of gender, age, and level of physical fitness often need to consider what we are eating on a daily basis in order to either gain weight or lose weight. One helpful and important aspect of many diets is the need to consider what kind of energy the food source being consumed will provide and allow you to do the most work. We often also evaluate how each food source will provide us with the nutrients we need.
PLANNING FOR THIS PROJECT:
You will need to make note or keep a diary of all the food you ate for one meal (3 items minimum) and take a photo of that meal. Make sure the photo is clear and all food items can be made out. Note also that you want to be able to describe the amount or serving size of each food item you consumed as well.
If you’re at a restaurant, often times they will have nutritional information about each food item – take a picture of this if possible
Before starting, do look through all of the questions below to get a feel for what will be asked and the purpose of the assignment.
NOTE: Three minimum reference sources are required. Your textbook, specifically Chapter 3 – Matter and Energy, would be very useful for this assignment.
ASSIGNMENT:
Address the questions listed below fully with complete sentences, inserting tables when necessary. Make sure to put it in your own words, paraphrasing and summarizing. Only use quotes when necessary, citing all sources used. Do make sure to apply the appropriate in-text citations when necessary. Make sure to review the Instructions page for this assignment as well.
For this assignment begin by reviewing Chapter 1, 2 and 3.
1. Create an “Introduction” section. In the first paragraph of this introduction, briefly describe the purpose of this assignment. Also write a brief paragraph(s) that addresses the following questions:
2. Using your notes or your diary of all the foods you ate in one meal. Tell us if it was breakfast, lunch, or dinner. The meal needs to include at minimum 3 food items. List the food items you ate during that meal along with their amounts (or serving size). Include a picture of all the food items. You can create a table similar to the below:
3. Review the Nutritional Facts for food each item.
4. You will be creating tables and a calculation section for what goes into your tables. Make sure to label all columns and rows. All other calculations can be shown with the individual questions below.
Create a table for your food items showing the “Composition and Energy Content” listing the energy value for each food type (mass of Carbohydrate, Fat and Protein) along with the total Energy. Example shown below.
Table 3.7 shows the energy values for food obtained from burning 1g of carbohydrate, fat, or protein in kilocalories or kilojoules.
Food Carbohydrate (g) Fat (g) Protein (g) Total Energy (kcal)
5. Using Table 3.7, calculate the total kilocalories for each food type in this meal (round off the kilocalories to the tens place) and fill in your table. Then calculate the Energy in kilocalories for each food type based on amount of mass, along with the total energy for the entire meal.
See example table below (but do not show your calculation inside your table, only the result).
FOOD ITEM SNACK CRACKERS
Energy Content Mass (g) x Energy Value = Energy
Carbohydrates(g) 19 g x 4 kcal/1g = 76 kcal
Fat(g) 4 g x 9 kcal/1g = 36 kcal
Protein(g) 2 g x 4 kcal/1g = 8 kcal
Total Energy = 76 kcal + 36 kcal + 8 kcal = 120 kcal
6. Based on the total energy for the entire meal, use Table 3.9 to determine
7. Using Table 3.10, determine the number of hours of sleep needed to burn off the kilocalories of this meal. (Show calculations.)
8. Using Table 3.10, determine the number of hours of swimming needed to burn off the kilocalories of this meal. (Show calculations.)
9. CONCLUSION:
Chemistry can feel like learning a new language. Not only are you dealing with chemical formulas, but also often problem solving with unit conversions, dealing with significant figures in calculations, etc…
If we treat it like a new language, then perhaps we can allow for a more successful approach in learning it. Just like not all classes are equal, not all students have the same approach to solving problems. Let’s use this discussion forum as a way to learn about what works for some people and what does not work. And it can also be a place to revisit for handy resources.
