Materials

This week we have started our science topic on materials and their properties.  Have a look around your house.  What materials can you spot?  Why are they used?   Try to use the key vocabulary we learned in class:

transparent
translucent
opaque
hard
soft
strong
breakable
flexible
waterproof
absorbent

For example the walls are made out of brick because it is strong, so it does not fall down in the wind.  Brick is also opaque which is great because it means you have privacy to change and shower.  In addition, brick is waterproof, so when it rains the water does not come in and make us wet.
