
you have a pair of scales
you have 12 coins
11 weigh the same
the other is heavier
How do you find the heavy coin if you are
allowed 3 weighings? ..
Programming
a computer can only do what it is told to do
 a program is a set of instructions telling a
machine what to do.
 programming involves learning how to write
instructions that do specific tasks

The Brain Project:
Neuroscience + Computer Science
We can use computers to see
what happens in a person’s brain
when they think, and to model how
the brain solves problems
Light traveling into the eye
Brain activity: what it
looks like when you think
A neuron:
your brain is made up of millions of these
Biology + Computer Science
We can use computer science
to find patterns in DNA, model
biological systems, determine the
structure of molecules, and much
much more…

So What is Computer Science?
We hope we have shown you that computer
science can be many things …. and computer
scientists can be many different types of people
……. including YOU!!
Puzzle 2.
You come to a fork in the road and meet a twin
and ask the way to go.
One twin always tells the truth
One twin always tells lies.
How do you decide which way to go?
Puzzle 3.

Three children sit one behind the other in a row. The third
child can see the first two, the second child can only see the
first and the first child can't see either of the other two.

A teacher has a box of five hats, two red ones and three
black ones. The teacher places a different hat on each of
the three children.

She instructs each one to call out the color of their hat once
they are sure of it. All of the children are perfectly logical.

Within a few minutes the first child correctly states the
color of her hat.

What color is it?
Puzzle 4.
There is a certain type of rope that when lit at one end, will take
an hour to burn.
The burning however is not uniform and so it might, for example,
take ten minutes for the first half to burn and fifty minutes for
the second half to burn.
You have two such ropes, but they are not identical
Your number of matches is not a concern.
How can you measure exactly 45 minutes?
Answer puzzle 1.


split into 3 lots of 4
take the first 4 coins and weigh against second lot
with one weighing you know if the heavy coin is in the 1st or
2nd group because the balance will go down … or if they
stay balanced it's in the 3rd group
now take your group of 4 coins and split into 2's
now you can separate the pair and see which is the heavy
coin.
To make this a more difficult problem try finding
the coin of different weight without knowing if it's
heavier or lighter .... think about it...
Answer puzzle 2.
You say to the twin "If I asked your twin
which road to take what would she say? "
....and then you take the other road...
Answer Puzzle 3

Black.
If the third child does not reply first then she must be
confused by the hats of the other two.
If the hats of the first two were red, then the third would
know she had a black.
The second child, hearing the silence of the third realizes
that he and the first child can't both have red hats.
If the first child has a red hat then the second child knows,
since he cannot also have a red hat, that his hat is black.
The first child, noticing the silence of the other two,
realizes that she cannot have a red hat.
Therefore, her hat must be black.
Answer Puzzle 4.
You set the two ends of one rope and one end of the second
rope on fire.
Once the first rope has burned out a half hour has passed.
By lighting the other end of the second rope at that time,
it will take fifteen additional minutes for the second rope to
completely burn out.
