Discussion. The discussion section should explain to the reader the significance of the results and give a detailed account of what happened in the experiment. Evaluate what happened, based on the hypothesis and purpose of the experiment. If the results contained errors, analyze the reasons for the errors.

It is accepted by the scientific community as a law when it has been tested in sufficiently various ways by sufficiently many people and has not been disproved.   Or, … more simply, it's not AN observation that becomes a law, it's MANY observations.   When an experiment can be done by anyone, anywhere, at any time, and the same result is achieved this suggests that that is the only result attainable from the experiment.

Parts of a Lab Report. Note: Most 100-level chemistry labs require only worksheets to be filled out at the completion of each lab. Therefore, this information would be most useful for 200-level students as lab reports are often required for those courses.

Observation is important in the scientific method in that it allows you to formulate what is going on in different situations, see a connection.

Observations Versus Interpretations in Science. An observation is any report from your 5 senses. It does not involve an explanation. An observation can also involve measurements. Such an observation is a quantitative one, as opposed to a qualitative one (no measurements). On the other hand, an interpretation is an attempt to figure out what has been observed. Here are some examples designed to help you distinguish between them. INTERPRETATION.

The discussion should contain: 1  Summarize the important findings of your observations. 2  For each result, describe the patterns, principles, relationships your results show. Explain how your results relate to expectations and to references cited. 3  Explain any agreements, contradictions, or exceptions.

Now that you have completed an experiment and have collected all of the necessary information in your lab notebook and any supplementary data from analytical instrucments, you need to write up your results in a lab report.

When doing labs, it is important not to confuse observations with interpretations. If you are asked to observe, you should not identify gases. Hydrogen gas was produced when zinc was added to acid is not an observation. What you see is the liquid getting cloudy with bubbles rising from the area surrounding the metal.

A brief summary of what was done, how, the results and your conclusions of the experiment. (Similar to the Abstract.). References. A listing of published works you cited in the text of your paper listed by author or however the citation style you are using requires the citation to be listed.

It does not always hold the same pattern if it occurs again. However an observation becomes a … scientific law when it has been accepted universally and is absolute and cannot be argued upon. A scientific law can be explained through history and research done on different phenomena.
