Buenos Dias!


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


TITLE: Measurements

  • Cut 3 times so you have 4 flaps.

  • Label each flap: mass, volume, length, & temperature

mass

volume

length

temperature

Measurements


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).

Measurements


…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.


Standardization

  • SI units were designed to provide a worldwide standard of physical measurement for science, industry, and commerce.

  • SI was adopted worldwide in 1960.


Now, have your foldable ready to record your notes!


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)


MASS

3. Instrument:

* Mass is measured using a

Triple

Beam

Balance


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.


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)


LIQUID VOLUME

3. Instrument:

* LiquidVolume is measured using a beaker, graduated cylinder, or a flask

Beaker

Erlinmeyer

Flask

Graduated

Cylinder

Volumetric

Flask


SOLID VOLUME

3. Instrument:

* Solid volumeis 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


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


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


SI based on units of 10
