go for hydro power plant
i made this model when i was in ninth
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
dynamo
stupid thing is eating my head....................................
Science uses evidence and well tested models to predict future events such as the weather. Predictions by science matter more than individual opinions because science is objective and has an extremely good track record.
what the tts wt im searchin for!!!!!! I believe only one working model cannot be constructed in physics - that of the universe itself
For an electron cloud model, the analogy would be the propeller blades on a plane.
no k
the same is searching i too
how to make a science models for 9th class
working models like electrical ones
battery charging shoes
Yes.
topics to make working models related to biology
plants and animals
The three types of models used in science are : Physical models Mathematical models Conceptual models
There are a number of different types of working models that you could use for a science exhibition. You could demonstrate the flow of water in the water cycle for example by setting up a fountain system.
working models for energy conservation are:- * * * * *
Models are useful in science, because it is easier for some to understand then words.
