Question

During a laboratory activity, a student combined two solutions. In the laboratory report, the student wrote, "A yellow color appeared." The statement represents the student's recorded:

(1) conclusion
(2) observation
(3) hypothesis
(4) inference

Answer 1

The phrase 'A yellow color appeared' is an observation made by the student during a laboratory activity as it describes what was seen without providing an explanation or conclusion.

Step-by-step explanation:

The statement "A yellow color appeared" represents the student's recorded observation. This is because an observation refers to the data or facts scientists collect as they conduct experiments. Observations can be qualitative, such as noting the appearance of a color, or quantitative, such as measuring a substance's temperature. After making observations, a scientist may form a hypothesis, which is a tentative explanation that can be tested through further experimentation. A hypothesis is not an observation, but rather a statement that predicts a possible outcome based on initial observations. If the testing supports the hypothesis, it may lead to a conclusion or even contribute to the development of a scientific law.
