· 3 fold brochure
·
Only need only write on
the inner three flaps
and
the 1 outer title flap
·
The flaps or columns
read down the page not across
·
A good idea is to type
it then paste onto the brochure or use a brochure maker if you have one on MS
Word or Wordperfect or some other word processor or publisher
My example: (This would get about
a 2 – it is just a fast example – it took me five minutes to write)
I have created a machine
called a lawnomatic
One of the chores I hate (not
really) is mowing the lawn
This machine mows the lawn
for me
All I have to do is press a
button, which starts the motor, the head light on the front of the machine
tells which grass is the tallest and it only cuts those pieces of grass. When
done it throws out the clippings itself, drives itself to the garage and turns
off.
There are many simple
machines in my lawnomatic - the button is a lever, the blades are wedges, the
wheels are wheel and axle and the motor has pulleys, gears, levers and other
simple machines. It has many benefits – it saves me time because I don’t have
to cut the grass anymore, I can now put my energy into playing with my gameboy,
my life is much better because I have gotten to level four and all my friends
think that is great. It is a compound machine because it has many simple
machines. It is a machine because it allows me to do a job with less effort
(input) and the output (the job) gets done faster and makes my life easier.
Another example:
My machine is called a wedge-o-wonder.
Wedges are wonderful simple
machines. They have so many purposes like door stops, scissors, knifes, nails,
and other things. My wedge-o-wonder is wonderful because all I do is set a dial
which has the details of what wedge I want, put the raw material down a chute
and out the other end comes my perfectly formed wedge or wedges. (Etc, et,c
etc, I wrote etc because I think you get the main idea)
