section ii deduction & explanation questions

1. explain why scientists in different countries need to use the same measurement standards
2. why would science be vague without measurement? give two examples
3. suppose one scientist uses feet and another uses meters for the same experiment. what problem might arise?

Explanation:

1. Scientists in different countries need to use the same measurement standards to ensure consistency and comparability of data across borders. This allows for seamless collaboration, replication of experiments, and the building - up of a unified body of scientific knowledge. For example, in climate - change research, if different countries use different standards for measuring temperature or carbon emissions, it would be impossible to accurately assess the global situation.
2. Science would be vague without measurement because measurements provide precision and objectivity. For example, in chemistry, without measuring the amounts of reactants, it would be impossible to predict the outcome of a chemical reaction accurately. In astronomy, without measuring the distance and mass of celestial bodies, our understanding of the universe would be very limited.
3. If one scientist uses feet and another uses meters for the same experiment, problems such as miscommunication, errors in data analysis, and difficulty in replicating the experiment may arise. For example, if one scientist reports a length as 10 feet and another expects it in meters, there will be a conversion error if not properly accounted for, leading to incorrect conclusions in the experiment.

Answer:

1. To ensure consistency, comparability, and seamless collaboration in scientific research across countries.
2. Because measurements provide precision and objectivity. Examples: Chemistry - reactant amounts; Astronomy - celestial body distances and masses.
3. Miscommunication, data - analysis errors, and replication difficulties may occur.
