Problem Statement:
Write an alphabet on a A4 size paper by pen or
pencil. (Except alphabet " I ")
COMPETANCIES TO CHECK:
·
Energy conversion in most economical way.
·
Aesthetic consideration.
·
Innovative or creative things used in model.
·
Cost consideration.
·
Accuracy and precision of model.
RULES AND
REGULATIONS:
- Minimum no
of energy conversion in model should be six.
- Minimum no
of steps for energy conversion should be ten.
- Dimension of
model should not be greater than length 8 ft*width 6 ft.
- No manual
interventions are allowed otherwise team will lose marks.
- Upper time
limit to do the task will be 5 minute.
- Use of
explosive things is prohibited.
- Same steps
and same energy conversion should not be repeated. If repeated it
will not be considered.
- At the time
of event, you will be provided with 230V electric supply only.
- Each entry
will be allowed two trials, so devices should be designed to allow
for quick resetting.
- Participant
has to submit their model write up, flow chart at the time of event.
- Please bring your fee receipt at the time of
event.
- Skipping of
step is allowed if some step is not working.
JUDGING CRITERIA:
Judges will
take decision based on following empirical relationship and jury’s
decision will be final one.
NOTE: In case of tie, team completing the task
in minimum time will get the benefit.
A4
size paper will be supplied by at the time of event.
FORMULA:
P=300A+40B-20C-20D+50E
Where,
A= final task (First attempt=1, Second attempt=0.75, Third
attempt=0.5 )
B=Types of energy conversion.
C=No. of intervention.
D= No. of steps skipped.
E=
No. of creative/innovative things
Energy classification:
- Different
forms of energies are: Kinetic energy, Potential energy, Wind
energy, Heat energy, Sound energy, Chemical energy, Light energy
etc.
- Vibrational
and rotational energy comes under Kinetic energy.
TIPS
1.
Plan your machine
on paper first. Use your imagination!
2.
Start with one to
two steps first – don’t get carried away! Begin with the last
step – what you’re required to do, and work backwards.
3.
From the garage,
junk drawer, or your desk, gather the essentials; string, balls of
different sizes, tape, empty cardboard tubes, more cut up cardboard
from pizza boxes, any junk. Sit down and roll the ball around.
Play with the stuff! See what it can knock over or make happen.
4.
For some fun, use
a mousetrap. Don’t use rat traps – you can break the bones in your
hand!
5.
Don’t use fire
- too dangerous
6.
Brainstorm – don’t
worry if an idea seems crazy – just write it down for now. The
idea is to look at things in a new way. Can the ball knock
down something else, or land on something, or pull something? Use
your brain!
7.
As someone once
said “gravity is your friend”. Use it!
8.
More things to
gather: wire, empty threads spools or pulleys, old toys, small
wheels.
9.
If there is time
later, make your machine sturdy from wood, nails, etc.,
10.
Remember
what your science teacher taught you about simple machine: levers,
inclined planes, wheels….
11.
Thought for
the day: - it’s better to have a few steps that work well, then 8
steps that don’t work at all!
