how to make any working model in physics?
A) go for hydro power plant
this is very easy
on a thermacol make two houses or hut one road and most importantantly one dam
buy one small motor this is easily available in markets
it will cost you Rs 50
it will hawe a shaft
attach turbine to it made of silver foil which we use for food packaging
take two bulbs use it as light of the huts
make two street lights near roads
while showing its working use battery or cells to light them
you can explain it as when turbine rotates it produces electricity which we ase for domestic or industrial purpuse
i know it will be hard for you to make it without seeing
but i will try to find out a photo graph of my model
other is solar energy in this olso u have to make huts roads and all
as solar cells r very costly u can make them using a mirror
It's Very easy to make and cheap.
You will need only :-
about 90 Straws
A couple of meters of Cello tape.
One can demonstrate a lot about waves from this model. Wavelength, frequency, amplitude, how speed of propagation increases as you increase tension etc. And as you are in 11th class, I think there is a chapter about waves and resonance also in Physics.
You can Find loads
Q) Working type?
Ans:when ur busy in any other work u can use this alarm ?? in bathroom while you fill ur bucket and this is so easy and simple to make it
Use your creativity rather than using YouTube or any other apps for your support.
I suggest you to do the working models based on resonance or pendulums (again, it's only a suggestion from my side).
Ask help of you seniors or simply your parents (they have the best ideas...).
Always have that feeling that what you are making is the best among all.
Hope it helped you to get some ideas..
