Question 1: Which types of evidence do scientists use to claim a practice is a pseudoscience? Explain your answer in 1–2 sentences.
Question 2: Elk in Yellowstone National Park were overgrazing the willow plant populations. Wolves were reintroduced and the willow plant population recovered. In three to five sentences, state two facts, make an observation, and make an inference.
Question 3:In 3–5 sentences, explain how scientists use creativity to construct and answer scientific questions.
Question 4:In 3–5 sentences, describe the similarities and differences between scientific laws and scientific theories.
Question 5:Scientists often collaborate in teams to draw scientific conclusions. In 1–2 sentences, explain why scientific collaboration is important to research.
Answer 1: Scientists use evidence such as lack of empirical support, reliance on anecdotal evidence, failure to meet the criteria of falsifiability, and absence of peer-reviewed research to claim a practice is a pseudoscience. These evidence help to demonstrate that the practice lacks the scientific rigor and credibility expected in genuine scientific inquiry.
Answer 2: Fact 1: Elk in Yellowstone National Park were overgrazing the willow plant populations. Fact 2: Wolves were reintroduced. Observation: After the reintroduction of wolves, the willow plant population recovered. Inference: The reintroduction of wolves likely resulted in the recovery of the willow plant population, suggesting a predator-prey relationship where the presence of wolves may have controlled the elk population, leading to improved vegetation.
Answer 3: Scientists use creativity in multiple ways to construct and answer scientific questions. They create innovative experiments, develop new methodologies, propose novel hypotheses, and think critically to generate alternative explanations. Creativity allows scientists to explore new frontiers, generate new knowledge, and push the boundaries of scientific understanding.
Answer 4: Scientific laws and scientific theories are both scientific principles used to explain phenomena. Similarities include being based on empirical evidence, being supported by data and observations, and being subject to scrutiny and testing. However, scientific laws describe a specific phenomenon or relationship and are often expressed in mathematical terms, while scientific theories provide broader explanations and frameworks that incorporate multiple related phenomena and can be revised or refined based on new evidence.
Answer 5: Scientific collaboration is important to research because it allows for the pooling of diverse expertise, resources, and perspectives. Collaboration enables scientists to tackle complex problems that may require multiple disciplines, to share and exchange knowledge and ideas, to conduct larger-scale studies, and to conduct more rigorous and reliable research. It also helps to enhance the objectivity, reliability, and validity of the scientific conclusions by subjecting them to scrutiny and peer review.
