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!
Good luck!
I would make my trainers hard so they can be able to go travelling and in rough conditions.Flexible because it can make it more comfy.Strong so it can’t break easily.And breathable fabric so it can make your feet more cooler.
Great ideas Albert! Can you think of some materials which fit your criteria?
I would make my trainers waterproof so that your feet don’t get wet, flexible so that you can move in them, cushioned so that they are comfy and breathable so that your feet don’t sweat.
Great ideas Vincent! Which materials would you use to ensure your trainers are all of these things?
I will send you a picture
I would put rubber on the bottom so it bounces and it stays in shape and put leather on the top so it’s more resistant from things on the front.
Good ideas Rafael!
I think would make them water
proof and strong but still comfy.
I would also make them breathable
sothat your feet can breathe.
Great ideas girls! Which materials would help your trainers to be all of these things?
I would make mine a thermal conductor so that it warms up your feet. I would make it hard so you could use it for hiking , climbing and any other sport.
I think the materials suitable for these trainers are, Nylon (thermal conducting) and rubber (for grip ) .
Ooo that is a good idea! Especially in the winter if you are using your trainers to walk/run outside!
I would make mine water proof ,flexible and comfy so I can go on long walks and it would be all right.
Great ideas Raimundo!
Which materials could you use to make the different parts of your trainers?
I would make it water proof incase if it hardly rains, try to make it comfortable by maybe putting an insole padding or a cushion tape so that the sneaker is not to big or oversized, rubber at the bottom so that you wouldn’t slip and can make an extra grip to where you are standing. Also, I would make my shoes flexible so that it’s not to stiff on the feet.
Great ideas Clare! Which materials could you use to achieve this?
I would make my trainers flexible so that it is easy to walk and run in them.
Good idea Clara! Which materials are flexible?
will send pic
Great, thank you!
