Narrator: Welcome to the 4DFrame competition,
Enlightening Imagination, 2020, the Wind Power Challenge.
This year's mission will be to create a machine
or a construction that can be good for our environment
in the future.
The model should have one or more moving parts
that can move in any direction
while interacting with each other
with the help of wind power.

The jury will assess how the model works
using a wind source, such as an electric fan
or a hair dryer.
Each team will receive a kit with 4DFrame material.
You have an hour and a half to complete your task.

Build your model, give your model a name,
write down the technical and scientific principles
that you've used.
You can also suggest creative alternative uses
for your invention.
Keep in mind that your model has to function properly.
You should also sketch your model on the enclosed form.
On the form provided, you will also need to describe
the characteristics of your 4DFrame prototype
and the technical and scientific principles
that you've made use of.
Points will be awarded for
the quality of your construction and your sketch,
your creativity, your ability to work as a team,
as well as the mathematical and scientific principles
that you've used.
The other materials you may use are,
pencil, ruler and scissors.
You are allowed to cut into the material

When your model is complete all residual materials
should be put back in the plastic bag.
A tip, use several different mechanical principles,
such as cog wheels, levers, and gears.
Remember that you're also judged on your general tidiness.
Good luck.
