Performing Biological Investigations How is the metric system important in science?

Scientific Measurement Most scientists use the ___________________ when collecting data and performing experiments. The metric system is a _____________of measurement whose units are based on certain physical standards and are scaled on multiples of _____________. Various _________________ allow you to convert from one unit of measurement to another in the metric system. Ex. Meters can be measured in ____________ (m) ____________ (dm) ____________ (cm) ____________ (mm) ____________ (km)

Base Units in the Metric System Measurement Definition Metric Base Unit Symbol Device Used to measure Length Distance between two points. Meter m Meter stick Volume Amount of space an object takes up. (length X width X height) Liter L Graduated cylinder Mass Amount of matter an object is made of.
