Matter
It is everything that has mass and volume
Mass: Is the amount of matter in an object.
Volume: Is the space occupied by a matter
Measuring Tools:
Measuring of Length
1(1)Measuring Tools:
a) graduated ruler.
b) ,, tape.
(2) Measuring Units:
• Length measuring units are: meter - centimeter.
• 1 meter = 100 centimeter.
• Mass measuring units are Gram - Kilogram.
• 1 kilogram = 1000 gram.
Exercise:
3- volume:
Measuring tools
-measuring units:
• Liquid volumes measuring unit is:
Liter or milliliter
Liter = 1000 milliliter or = 1000cm3
• Solid volumes measuring unit is
The Cubic meter (m3) or the cubic
Centimeter (cm3).
Estimating volumes of solid objects:
Solid objects may be regular or irregular in shape:
Calculating the volume of a regular shaped solid object:
Like your science book, regular box
Volume of cuboid = height × Width × Length
· Estimating Volumes of irregular shaped solid objects
Like piece of stone
• Liquid volumes measuring unit is:
liter or milliliter
Liter = 1000 milliliter or = 1000cm3
• Solid volumes measuring unit is
the Cubic meter (m3) or the cubic
centimeter (cm3).
