The Metric System
Length is a measurement of distance.
Length is measured using the tools:ruler meter stick tape measure
Length is measured in the basic unit: meter
Volume is the amount of space taken up, or occupied, by an object.
The volume of a liquid can be measured easily by reading the meniscus.
The meniscus is the curve at a liquids surface.
Liquid volume is measured using the tools: beakers, Erlenmeyer flasks, graduated cylinders, and pipettes
Liquid volume is measured in the basic unit: liter(L)
The volume of a solid can be calculated by measuring the length, width and height of a solid object.
The equation to calculate the solid volume is length X width X heightV=LxWxH
Solid volume can be measured using the tools: a ruler, a meter stick, or a tape measure
Solid volume is measured in the units cubic centimeters (cm3)
To convert liquid to solid volume 1mL=1cm3
Mass is a measure of the amount of matter in an object
Mass is always constant for an object, no matter where it is located in the universe.
Mass can be measured using the tool: balance.
Mass is measured in the units: grams(g)
Weight is a measure of the gravitational force on an object.
Weight varies depending on where the object is in relation to the Earth.
Weight can be measured using the tool: spring scale
Weight is measured usingthe units: Newtons (N)
Temperature is a measurement of heat in a substance.
Temperature can be measured using the tool: thermometer
Temperature is measured using the units Celcius (C)

The Metric System The scientific system of measurement
Types of quantitative observations
How do we measure things in science?
Metric Unit Review. Can you name the base Units? Mass – Grams Volume – Liters or cm³ Temperature – Celsius Length – Meter Time – seconds.
Reason 1: helps scientists share and compare their data/ results
Types of quantitative observations. International System of Units 1. Known as SI units (System International) – Official name of the metric system. –
Measurements and the Metric System
Measurement and Matter Unit 1. Meter The metric unit used to measure length.
You will have 4 minutes to answer the questions on the next slide.

Metric Review. International System of Units (SI) Base of 10 1 meter = 100 centimeters=1000 millimeters Standard Units: -Mass = gram (g) -Length = meter.
The Tools of Physical Science. Objectives Today we will learn –About graduated cylinders –About triple beam balances –About the three temperature scales.
Standard measure of a quantity Examples › Length = Meter (m) › Volume = Liter (L) › Mass = Grams (g) › Temperature = Celcius (°C)
Measurement The International System of Units (SI) is the standard system used around the world.
