Science Year 2 lesson 6

Slide 1 - Tekstslide

Learning Goals
I can…
  • Explain the concept of density
  • Calculate the density of a substance using the density formula.
  • Use density to determine the mass or volume of a substance
  • Use density to identify an unknown substance

Slide 2 - Tekstslide

Key Words
  • Mass
  • Volume
  • Density

Slide 3 - Tekstslide

Density
Density = a measure how much matter is packed into a given area. It is a property of a substance.
The closer the molecules are, the greater the density.
Density tells us how many grams of matter there are per a unit of volume.


Slide 4 - Tekstslide

Density calculations



Common units:
  • grams per cubic centimeter (g/cm3) 
  • grams per milliliter (g/mL)
