Objectives
• Today we will learn – About graduated cylinders– About triple beam balances– About the three temperature scales– The definition of mass, volume and
temperature.
The Graduated Cylinder
Volume: A measure of the amount of 3 dimensional space an object occupies.
Base Metric Unit = Liters
An object dropped into a cylinder will displace an amount of water equal to its volume!
Other ways to find volumeOther ways to find volume
Volume of a cube = L x W x HVolume of a cube = L x W x H
3 cm
3 cm
3 cm
So, 3cm x 3cm x 3cm = 27cm3 or 27 ml !!!!So, 3 cm x 3 cm x 3 cm = 27 cm3
The Thermometer
Temperature: A measure of the energy in an object.
• How hot or cold something is!
Units = Degrees Celsius
Other ToolsSpring Scale
Measures Force of Gravity
Units = Newtons
Stopwatch
Measures time
Units = Seconds
