Finding melting/boiling points of substances is an example, its logical, find it out yourself.
When collecting data
Scientists use the metric or SI units of measurement.
You presuppose that scientists think in the same restricted way as the rest of the population.
All scientists use the metric unit of measurements because it is the most accurate.
Scientist cannot safety do anything with measurements. They have to measure everything out.
Scientists use the System Internationale - the international system of units. This is a metric system. Most countries have switched to the metric system for everyday ie in shops and in the kitchen.
Scientists look for observable patterns and they measure whatever is objectively quantifiable.
to find accurate information
Science, including counting, relies on exact measurements and observations.
Because
Simply to make a series of 'standard' measurements that are recognised in any country.
What measurements are you performing? Make sure you aren't bitten if it's large, and make sure you don't kill the animal (unless you need it to be dead)
They use the Metric system.
Scientists who work temporarily in Antarctica measure whatever their specialty might be, in search of answers to questions that affect the health of planet earth. These elements include animal body counts, weights and measures of marine creatures, density and make-up of ice; atmospheric measurements, including wind speed, temperatures and humidity, and astronomical measurements, including distances to celestial objects. Sonic mapping of the continent's geography may also produce measurements -- and more. The standard for measurements is the metric standard.
They use scientific notation for very large or very small measurements
1) It is an international standard, so all scientists use the same measurements. For comparison, for example, different countries have different definitions of a pound. 2) Calculations are easier, because of the decimal prefixes.
If they are sensible, they will use those units defined and agreed by the International Standards Organization (ISO), as these will be universally understood and normally are required to be used in scientific publications.
