1 . The International system of units (SI units)Understanding:
1.U2: The International System of units (SI units) are a standard of measurements used in science around the world. Objectives:
|
Mass vs Volume vs Length
Mass: the amount of matter in an object Mass Units: pounds (lbs), grams, kilograms Volume: the amount of space an object takes up Volume Units: milliliters (ml), gallon, pint, liters (L), cm cubed Length: the measurement between 2 points Length Units: miles, kilometers, inches, feet |
SI UNITS
Since accurate measurement is a vital tool for doing science, a consistent set of units for measurement is necessary. Physicists throughout the world use the International System of Units (also called the SI system). The SI system is basically the metric system, which is convenient because units of different size are related by powers of 10. The system has physical standards for length, mass, and time. These are called fundamental units because they have an actual physical standard.
