Lesson content:

"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!
