Rules
At the start of this game you will be one nanometre tall. This is one billionth of a metre. The aim of the game is to
grow back to your normal size.
START
Place your pawns on the W5 symbol. Roll the dice. The player with the highest number begins the game.
When you land on a square where a ladder starts, you must go up the ladder to the square where it
ends. This means you’ll grow in size a lot quicker than when you have to follow the board.
When you land on a square with the head of a snake, you must go down the snake to the square
with the tail. This means you’ll shrink again.
SIZE
Some squares give you information about your size. Please use the size chart to help you put your size into
perspective.
TASKS
When you land on a Task square, the whole team has to carry out the task. When finished, ask a facilitator or
teacher to check your answers. If all answers are correct everyone can move to the next square (if the next
square has a snake’s head on it you can move passed this square).
END
To win the game you have to land exactly on the last square. For example, if you have only 3 squares to go and
you roll a 5, you’ll have to go to the end square and then move back two places again.

Task 1- True Or False
Decide if the facts about nanotechnology are true or false.
1) The average human hair grows about one nanometer per second.
True
False
2) A nanometre is one billionth of a centimetre.
True
False
3) Using nanotechnology we can make non-stain and non-wrinkle clothing.
True
False
4) Medical scientist in the next twenty years will be able to send small robots through our veins to
fight disease or perform surgery.
True
False
5) Using nanotechnology scientists will be able to create self-replicating robots which will
consume all living matter on the earth (also known as ‘Grey Goo’).
True
False
6) Geckos can walk upside-down because of tiny hairs only 200 nanometres wide on their feet
that glue them to the ceiling.
True
False

Task 2 – Match The Meaning
Match the word on the left to the definition on the right.
Nucleus
Nano
A particle with a positive charge, found in the nucleus of an atom
Out-of-control self-replicating robots consume all life on Earth
A particle with no electric charge, found in the nucleus of an atom
Electron
Grey Goo
Buckybal
l
Atoms
Proton
The Greek word for ‘dwarf’, also means one billionth
A very strong molecule, made up of 60 carbon atoms that form
the shape of a football
A particle with a negative charge, found in the space surrounding
the nucleus of an atom
All elements are made of these. Consist of a nucleus with protons
and neutrons, surrounded by electrons
Neutron
The centre of a cell where genetic information is usually stored

Task 3 – Atomic Structure
Proton – small particle with a positive charge found in the nucleus of the
atom
Neutron – a particle with no charge found in the nucleus of the atom.
Electron – very small negatively charged particle found in the space surrounding
the nucleus
We can find the atomic structure by using the atomic number and mass number. These give us the
information needed to see how the atom is built up.
Atomic Number = the number of protons in the nucleus of an atoms = the number of electrons
Mass Number = the number of protons + the number of neutrons

Atomic Number
Number of Protons = Atomic Number = 6
Number of Neutrons = Mass number – number of protons = 6
Number of Electrons = Number of Protons = 6

Task 4 – Scanning Electron Microscope images
Below are five images and five labels. Cut the images and labels out and match them
up. Then stick them on the spare page in order of size from the smallest to the largest.
