1. Measurements!

2. Background on SI Units
Scientists use the metric system which is the international system (SI) of measurement.
France was the 1st country to adopt the metric system in 1795.

3. Standardization
SI units were designed to provide a worldwide standard of physical measurement for science, industry, and commerce.
SI was adopted worldwide in 1960.

4. MASS 1. Definition: * Mass is the amount of matter in an object.
2. Base Unit:
* gram (g)
* larger masses = kilogram (kg)
* smaller masses = milligram (mg)

5. MASS
Triple
Beam
Balance or
Digital Scale
3. Instrument:

6. REMINDER about MASS
Weight is a measurement of force, and will change depending on gravity.
The weight of an object can change but the mass remains the same.

7. VOLUME
1. Definition:
* Volume is the amount of space an object takes up
2. Base Unit:
* liquid volume = liter (L)
* solid volume = cubic meter (m3)

8. LIQUID VOLUME Beaker Erlinmeyer Flask Graduated Cylinder Volumetric
3. Instrument:
* Liquid Volume - beaker, graduated cylinder, or a flask

9. SOLID VOLUME 3cm x 2cm x 4cm = 24cm3 L x W x H = V 3. Instrument:
* Solid volume - metric ruler using the formula:
L x W x H = V
3cm x 2cm x 4cm = 24cm3

10. LENGTH 1. Definition: * Length is a measure of distance 2. Base Unit:
* meter (m)
* longer lengths = kilometers (km)
* shorter lengths = centimeters (cm)
3. Instrument:
* metric ruler
* for very large distances: light year

11. TEMPERATURE 1. Definition:
* Temperature is the measurement of the amount of heat in an object
2. Base Unit:
* Celsius (⁰C)
* very hot or very cold temperatures = degrees Kelvin (K)
3. Instrument:
* thermometer
