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

Answer 1

The statement "A yellow color appeared" made by a student in a laboratory report is an observation, which is a direct recording of an event experienced in an experiment. Observations differ from hypotheses, conclusions, and inferences, as they are immediate and factual without involving conjecture or analysis.

option 2 is the correct

Step-by-step explanation:

In the context of a scientific experiment, when a student notes, "A yellow color appeared," this statement is best categorized as an observation.

An observation is a factual reporting of an event or a phenomenon that is directly experienced through the senses or with the aid of scientific equipment. In contrast, a hypothesis is a tentative explanation made on the basis of limited evidence as a starting point for further investigation.

A conclusion is drawn after testing a hypothesis through experiments and analyzing the results, whereas an inference is a logical interpretation or explanation based on the observation.

Take for example the observations mentioned: 'A green solution and colorless solution are mixed. The resulting mixture is a solution with a pale green color.' and 'Two colorless solutions are mixed. The resulting mixture has a yellow precipitate.' These are both examples of qualitative observations, which do not rely on numerical measurements but rather describe the characteristics or changes that occurred during the experiment.
