see your physics book
no idea dudes....
To make a working model in geography, you first need to decide on the topic or concept you want to represent. Then, gather materials such as maps, clay, paper, or other items to build your model. Use these materials to create a physical representation of the geographical concept you are studying, such as a mountain range, river system, or ecosystem. Be sure to label and explain the components of your model to show how they interact in the geographical setting.
I think you should make a "HYDROELECTRICITY". but the process is that the electricity will be produced by domestic waste water and you can also include "The purification of water'. you can purify the domestic waste water after producing electricity through hydroelectricity.
A simple model involves using thermocol. Drawing water cycle on its surface.
A mechanical working model of the solar system is called an orrery. Many observatories have them, as do thousands of individuals.
windmill
There are many ways in which you could build a simple working model of an ear for a science fair. You could build this out of paper mache for example.
COLING BELL give the lsit of working models in the wikipidea
make a toothpick windmill that's the easiest way...and if it has to move then put a remote fan next to it
go to windmill park with a giant crain and then pick the windmill and drop it to your school.
How do you build a working model of science and technology for games and sports?
You would not be able to obtain the fissile material necessary to build a working model of a nuclear power plant. You could build a model, for sure, but it would not be a working model.
you can build it out of anything if you are smart
Its simple and easy to understand, best of all it really works and there is some amount of physics that goes behind a windmill, you will scratch on the electronics parts.A good unique and sense full model of physics can only be made while the maker will be careful and knows how to make a clean projected and the project mainly depends on the presentation, and if you are looking for something on physics, why don't you try a working model of a windmill?? (dc motor, wires etc). And if you want procedure then i can give that too.....! So, best of luck i hope your project will be the best.....!
you cant
A working model of a windmill is easy to construct from popsicle sticks. Simply place four popsicle sticks across each other at angles. Then put a nail through the middle of the sticks to attach them all together making the hole a little bigger than needed. Attach to a base.
Make a small prototype of a "Helical" windmill which is very simple and innovative if you can get a fabricator to work for you. And yes...a helical windmill is one which rotates(and in the same direction) irrespective of the wind direction.
