CER EXAM LATEST QUESTIONS WITH CORRECT ANSWERS

CER EXAM LATEST QUESTIONS WITH CORRECT ANSWERS How do scientists collect evidence? - Answer-Through observations, experiments, measurements, and collecting samples. Why must evidence be objective? (Not Opinion or Feelings) - Answer-To ensure it accurately reflects the true outcomes of experiments without bias. Story-based evidence is good enough to prove scientific claims. - Answer-False. Scientific claims require more rigorous, systematically collected evidence. Not just a story you heard. What is the difference between qualitative and quantitative evidence? - Answer-Qualitative evidence describes qualities or characteristics, while quantitative evidence involves numbers and measurements. How should evidence be presented to support a claim? - Answer-Clearly and logically, often in the form of charts, graphs, or written data analysis. What is reasoning in the context of CER? - Answer-Reasoning is the explanation of how the evidence supports the claim. Why is reasoning necessary in a scientific argument? - Answer-It connects the evidence to the claim, showing explicitly how one supports the other. Give an example of reasoning in a science experiment about plant growth. - Answer-If plants grow taller in sunlight than in the dark, then sunlight must contribute to growth because it provides energy necessary for photosynthesis. Can reasoning include theoretical explanations? - Answer-Yes, reasoning often involves theoretical explanations that relate the evidence to scientific principles. How should reasoning be structured in a scientific explanation? - Answer-Clearly and logically, explaining the relationship between evidence and the claim step-by-step. Reasoning should consider alternative explanations for the evidence. - Answer-True. Good reasoning evaluates and rules out other possible interpretations of the evidence. What role do scientific principles play in reasoning? - Answer-They provide the underlying theories that explain why the evidence supports the claim. How can reasoning help in predicting outcomes? - Answer-By applying the same logical connections, reasoning can predict what might happen under similar conditions. Why is it important for reasoning to be detailed? - Answer-Detailed reasoning helps others understand the thought process and validate the conclusions. What is a "claim" in science? - Answer-A claim is a statement or conclusion that answers a question or problem. What should a good scientific claim be based on? - Answer-A good scientific claim should be based on observable and measurable evidence. How can a claim in a science experiment be proven? - Answer-By gathering and presenting evidence that supports the claim. A claim is the same as an opinion. - Answer-False. A claim in science is supported by factual evidence. Give an example of a claim about plant growth. - Answer-Sunlight speeds up the growth of most plants. Why is it important to make clear claims in science? - Answer-Clear claims guide the direction of research and help others understand your conclusions.
