Q

Atoms join one another to form molecules.

17
Q

Some things are made from just one type of element…but most are made from several mixed together.

18
Q

Coins are often made from nickel.

19
Q

The way they are mixed together affects how they look and feel - whether they’re strong or flexible, light or heavy.

20
Q

Carbon is a very important element.

21
Q

There’s carbon all over the world, in every living thing - from daisies to oak trees, beetles to blue whales.

22
Q

You probably have graphite in your schoolbag - it’s used to make the lead in your pencils.

23
Q

Scientists discovered that they could take one layer away from graph to create a brand-new material, which they called graphene.

24
Q

Graphene is so thin that it’s see-through, but it’s more flexible than rubber and stronger than steel.

25
In fact, it's the strongest material known to human beings.
Nano
26
IF you made a tightrope out of graphene, an elephant could walk along it without breaking it.
Nano
27
We're already using graphene to make: stronger lighter airplanes that need less fuel to stay in the sky - which makes less air pollution in the air...

windowpanes that was themselves using only sunlight...

and medicines that doctors can steer through your body so that they end up in exactly the right place.

There's plenty more in store.

These super-sieves could make seawater safe to drink - which could help millions of people in need of clean water
Nano
33
The glasses would send the person pictures of the world around them
Nano
34
But it takes years of testing to find out if new materials are safe to use- to be certain they won't hurt us or our planet.
Nano
35
Scientists all over the world are helping to speed that process along by sharing advice and new ideas.
Nano
36
There are so many secrets left for scientist to unlock
Nano

And who knows: the person with the key might just be...YOU!
