I want one good science experiment to perform in science exhibition please recommend me good one
Answers
some science experiments which can help you are
INVISIBLE FORCE
The objective: The purpose of this project is to test if magnetic levitation would reduce friction and understand how magnetic forces can be applied to train technology.
Methods/Materials
A magnetic track laid with ceramic magnets and bordered by magnetic side rails, along with a conventional track, were placed on a board. For the maglev train, three neodymium magnets were glued to each side panel while the base had 16 neodymium magnets to provide it with enough repelling magnetic force to levitate on the track. A standard train was the control. The track was then tilted at three different heights and the trains were timed based on the seconds it took to reach the other end.
SUNLESS SUNFLOWER
The objective: The objective was to test how the intensity of artificial light affected the growth of sunflower plants. My hypothesis was that the plants closest to the light will grow the tallest, then wilt, because of phototropism; the plants farthest away, will not have enough light to carry out normal cellular processes and barely grow; the plants in the middle group will grow the second tallest, but be the healthiest
Methods/Materials
Sixteen sunflower seeds and terra cotta pots, potting soil, fertilizer, four agro-lights, a plant light intensity meter, thermo-hygrometer, moisture meter, soil pH meter and timer were used. The soil was checked to ensure it had a pH of 6 to 7.5 for optimum growth. The moisture level of the soil was measured regularly and kept between 5 and 6. The thermostat and the thermo-hygrometer were set to 65°F. The control plant, was placed outside at sunrise. Simultaneously, the timer turned on the agro-lights for the 15 experimental plants, kept in three groups (five plants each) at a distance of 20, 60, and 100 cms from the artificial lights. The control plant was placed under artificial light at sundown so that all 16 plants got the same Critical Light Exposure Period of 14 hours. The plants were measured every week during the 5-week study period.
I hope this answer helps you
P.S: if you like my answer mark it as the brainliest
I will give you ideas . This is my state won science project ..
Topic :-" Reusing waste water from nuclear power plants ".
Abstract:-
Just make a demo of nuclear power plants. our main concept is to avoid the waste water into useful things
Because nowadays the water which is radiated are settling down into the ground or passing to any near lakes or rivers.
It affects the whole environment and surroundings. In order to avoid that we are doing this project.
First of all the water is fully radioactive. We have to convert it for our purposes.
It is here converted by a method called " liquid fluorine nuclear reactor ".
Hope you get for an idea!!
Between all the best for the competition!!!!
