Chapter 1.4, Problem 1CT
What if everyone in the government used the scientific method to analyze and solve society’s problems, and politics were never involved in the solutions? How would this be different from the present situation, and would it be better or worse?

The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing. It is important to consider what the experts say, but to also evaluate their statements. We will start with the scientific method.
I want you to outline the scientific method from what you have been taught in previous classes. You can list steps, parts, process, short descriptions, whatever. If not taught in previous classes, then you will make your best guess about it.
For you what are some of the weirdest scientific experiments ever done? And what are some of the weirdest scientific experiments ever done?
why do we solve problems in a scientific way?

- If all scientists use the scientific method to try to arrive at a better understanding of the world, why do so many debates arise among scientists?arrow_forwardThe Chemistry in Focus segment titled Dr. Ruth—cotton Hero discusses the enormous contribution of Dr. Ruth Rogan Benerito to the survival of the cotton fabric industry in the United States. In the discussion, it was mentioned that Dr. Benerito became a chemist when women were not expected to be interested in, or good at, scientific subjects. Has this attitude changed? Among your own friends, approximately how many of your female friends are studying a science? How many plan to pursue a career in science? Discuss.arrow_forwardGive two examples of chemistry in your every day lifearrow_forward
- We commonly encounter chemical reactions in daily life such as fire and biological metabolism. Cite at least two (2) examples of real-life situations that involve the Law of conservation of mass and explain how these affects you.arrow_forwardHow is scientific writing different from the style of writing that you learned in ENG 111? (Select all that are correct.) Group of answer choices a. Scientific writing is concise, written in 3rd person, and uses past tense. b. Science writing uses lots of colorful language to describe visual reactions to the experiment. c. Science writing uses lots of personal pronouns (e.g., I, me, we, you, your, our) to show ownership of the results and personal attention to directions. d.Science writing assumes the reader already knows how to do the experiment that is the subject of your paper. e.Science writing may include references that are from peer reviewed sources.arrow_forwardWhy should nonscience majors study science?arrow_forward
- Some scientists think there are living things smaller than bacteria (New York Times, January 18, 2000, p. D1). Called nanobes, they are roughly cylindrical and range from 20 to 150 nm long and about 10 nm in diameter. One approach to determining whether nanobes are living is to estimate how many atoms and molecules could make up a nanobe. If the number is too small, then there would not be enough DNA, protein, and other biological molecules to carry out life processes. To test this method, estimate an upper limit for the number of atoms that could be in a nanobe. (Use a small atom, such as hydrogen.) Also estimate how many protein molecules could fit inside a nanobe. Do your estimates rule out the possibility that a nanobe could be living? Explain why or why not.arrow_forwardThis section presents several ways our day-to-day lives have been enriched by chemistry. List three materials or processes involving chemistry that you feel have contributed to such an enrichment, and explain your choices.arrow_forwardAs stated in the text, there is no one scientific method. However, making observations, formulating hypotheses, and performing experiments are generally components of “doing science.” Read the following passage, and list any observations, hypotheses, and experiments. Support your answer. Joyce and Frank arc eating raisins and drinking ginger ale. Frank accidentally drops a raisin into his ginger ale. They both notice that (lie raisin falls to the bottom of the glass. Soon, the raisin rises Lo the surface of the ginger ale, then sinks. Within a couple of minutes, it rises and sinks again. Joyce asks. “I won der why that happened?” Frank says. I don’t know, hut let’s see if it works in water.” Joyce fills a glass with water and drops the raisin into the glass. After a few minutes, Frank says, “No, it doesn’t go up and down in the water.” Joyce closely observes the raisins in the two glasses and states, “Look, there are hubbies on the raisins in the ginger ale but not on the raisins in the water.” Frank says, ‘it must be the bubbles that make the raisin rise.” Joyce asks, “OK, hut then why do they sink again?”arrow_forward
- Discuss some ways in which chemistry has changed technology. Give one or more examples of how chemistry has affected another science.arrow_forwardIn Section 1.3 the statement is made that it is worthwhile for scientists, auto mechanics, doctors, politicians, and poets to take a scientific approach to their professions. Discuss how each of these people could use a scientific approach in his or her profession.arrow_forwardHexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids. Describe what you expect to see.arrow_forward
