science experimentsWhat can be the interesting science experiments that can be performed in a science exhibition by a high school student? could you please explain the procedure too.
The procedure you need to follow is the scientific method. Ask a question or state a problem you want answered. Then, do research about what is known on the topic. Formulate a hypothesis--a possible answer to your question. Design and perform a controlled experiment. Do data analysis and come up with conclusions. Share out your findings. What about something to do with obesity in young people? That is a very important issue these days.

You can make many things in your science exhibition -
I have made millions of them -
If this is your first experiment, build a wind mill that can generate electricity -
The steps are -
Get a propeller and make a stand to fix in propeller.
After fixing the propeller in the stand -
Attach a motor to the propeller -
You don't have to bring a battery -
Now, attach the two terminals of a LED bulb to the two terminals of the motor.
Your device is almost ready -
Bring a small table fan -
It is done -
Take your device in the exhibition hall,
Place your wind mill face to face to the table fan, now you "on" the fan.
Mission Accomplished -
Your propeller will rotate and the LED bulb will glow -
This is wind energy converted in to rotational energy and rotational energy is converted into electrical energy!!
