NDQ_014070 | Scientific research may involve creativity as well as reason. | null | a. true, b. false | a | T_4644 | text | null | Science is more about gaining knowledge than it is about simply having knowledge. Science is a way of learning about the natural world that is based on evidence and logic. In other words, science is a process, not just a body of facts. Through the process of science, our knowledge of the world advances. | 0.703819 |
NDQ_014070 | Scientific research may involve creativity as well as reason. | null | a. true, b. false | a | T_1905 | text | null | Most scientific theories were developed by scientists doing basic scientific research. Like other sciences, life science may be either basic or applied science. | 0.700527 |
NDQ_014070 | Scientific research may involve creativity as well as reason. | null | a. true, b. false | a | T_4830 | text | null | Investigations are at the heart of science. They are how scientists add to scientific knowledge and gain a better understanding of the world. Scientific investigations produce evidence that helps answer questions. Even if the evidence cannot provide answers, it may still be useful. It may lead to new questions for investigation. As more knowledge is discovered, science advances. | 0.681954 |
NDQ_014070 | Scientific research may involve creativity as well as reason. | null | a. true, b. false | a | T_1499 | text | null | If we were doing a scientific investigation we need to gather the information to test the hypotheses ourselves. We would do this by making observations or running experiments. | 0.67061 |
NDQ_014070 | Scientific research may involve creativity as well as reason. | null | a. true, b. false | a | T_3382 | text | null | Modern science is a way of understanding the physical world, based on observable evidence, reasoning, and repeated testing. That means scientists explain the world based on their own observations. If they develop new ideas about the way the world works, they set up a way to test these new ideas. | 0.660714 |
NDQ_014070 | Scientific research may involve creativity as well as reason. | null | a. true, b. false | a | T_3758 | text | null | Research in physical science can be exciting, but it also has potential dangers. Whether in the lab or in the field, knowing how to stay safe is important. | 0.649935 |
