Summary ? Lesson Question Measurement How are things measured using the metric system? Answer (Sample answer) Scientists measure using the metric system. In the metric system, measurements of length, volume, mass, and temperature can be shown using different prefixes, which represent multiples of ten. In this way, the metric system is an advantage when trying to compare two measurements. Slide 2 Review: Key Concepts Science uses the metric system for measurements.
