1. Buenos Dias!

2. Today, you will take notes using a foldable:
Fold your paper “hot dog” style and leave about ¾ inch for a title strip.
Fold it in half the other way and half again so that you have 4 sections.
FOLDABLE TITLE

3. TITLE: Measurements Cut 3 times so you have 4 flaps.
Label each flap: mass, volume, length, & temperature
Measurements
mass
volume
length
temperature

4. Measurements
mass
volume
length
temperature
Foldable Con’t:
Under the top part of the flap you will draw, label, and color the instrument used to make the measurement
Under the bottom part of the flap you will copy definition and information about the base unit (copy BLACK text only).

5. …BUT FIRST: 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.

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

7. Now, have your foldable ready to record your notes!

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

9. MASS
3. Instrument:
* Mass is measured using a
Triple
Beam
Balance

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

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

12. LIQUID VOLUME Beaker Erlinmeyer Flask Graduated Cylinder Volumetric
3. Instrument:
* Liquid Volume is measured using a beaker, graduated cylinder, or a flask

13. SOLID VOLUME 3cm x 2cm x 4cm = 24cm3 L x W x H = V 3. Instrument:
* Solid volume is calculated measuring the sides with a metric ruler and then using the formula:
L x W x H = V
3cm x 2cm x 4cm = 24cm3

14. LENGTH 1. Definition: * Length is a measure of distance 2. Base Unit:
* for length = meter (m); longer lengths = kilometers (km); shorter lengths = centimeters (cm)
3. Instrument:
* Length is measured using a metric ruler; for very large distances, we use the light year

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