SCIENCE : Unit 2. Rocks and Minerals.
         
Lesson content:

1.Minerals: Definition, Characteristics and  names of minerals.
 
"All about minerals"

2.Properties.
We have studied 4 main properties:
  • Colour
  • Lustre: shiny, metallic or dull.
  • Visibility of crystals
  • Hardness: hard or soft.
But we include some more properties for children that always need more challenging information.This gives me the chance to talk about many more minerals and uses.They are :
  • Size:large,small, medium size or big.
  • Permeability : permeable or impermeable.
  • Weight : heavy or light.
  • Transparency : transparent or opaque.
  • Shape: geometric, irregular round and oval.
  • Texture: rough,smooth or sharp.
  • Conductivity: we can heat it or cool it.  

 
3.Uses.
Minerals are around us and we use them form many things. In this part of the unit I have tried to used real objects to help the students to identify minerals and uses and to remember the vocabulary.
An easy example could be : "we use graphite to make the leads in pencils"




Here you have a game to  help you to remember the different uses of minerals. 
Have a good time and learn!
