Hello Class 5!
In Science you have been learning all about materials.
In class last week you explored some different materials and used some scientific vocabulary to describe them:
Hard: resistant to scratching or pressure.
Tough: resists cracking: opposite to brittle.
Strong: resistant to tearing.
Rigid: hard and fixed; not flexible.
Elastic: returns to original shape when force removed.
Plastic: retains new shape when force removed.
Flexible: easily bends; opposite of rigid and stiff.
Electrical conductor: material that allow electricity to flow through it.
Thermal conductor: material that allows heat to pass through it.
If you were designing a new pair of trainers, which materials would you use for the different parts and why?
I you would like to draw your design and label the different parts and materials then you can send it in through the homework uploader!
Think about the purpose of a trainer and ensure you clearly explain the reasons for each of your choices of materials!
