Here is a list of science experiments with water which you can use to rock your next science fair competition.

1. Diffusion: It is the process through which two gases and water mix.
It is instigated by the arbitrary motion of the molecules. The molecules present in the water starts moving around everywhere and triumph the molecule of the food colourant. Progressively the molecule of the food colourant moves through the water body and if you leave the food colourant in the water for a long time it dispersed in the water.
How to do the experiment.
Try to Drop a coloured drop into the centre of the water after stirring the water.
When mixing the water, you have seen the molecules of the water are moving randomly but, in motion, and the food colourant starts to be dispersed into the spiral motion.

What is the shape of the water appearing when you stirred the water?
The shape of the water appears to be in a concave shape. This is a vortex and whirlpool. The moment of the water is fast & steady, in a particular motion from the middle centre of the water body and lowers the pressure at the edge of the water according to Bernoulli’s principle thus, the pressure from the atmosphere depresses in the centre of the water than at the edge.

2. Water is able to uphold a domed (convex) surface due to the surface tension.
The surface tension of the water spill on the penny is lower than the weight of the water due to a force. If you are vigilant, you can again overfill a glass and that ultimately called the level of the water rise higher than the glass’s water capacity level.

3. Planting trees decreases erosion since soil can bind to the roots, the soil that sticks together more and more because of the water and will resist the soil erosion in a better and fast way. You can use water as soil erosion resistant.

4. Sound is conveyed by pressure waves.
Whales in the water are more able to interconnect over hundreds and thousands of miles. Water is very good at conveying pressure wave than air as it has the propensity to return back to its innovative location so the alteration in pressure is upheld better in water than air. It is proving that sound travels faster in water than in air. In water, it travels in a speed of 1500metres per second and the air it travels 350 metres per second.

5. Vinegar and water are miscible
it means they can dissolve in each other. Though, they will both have the ability to disappear at room temperature. If you leave the vinegar in a container then you can smell it from the distance that means the diverse fluid will ultimately evaporate. It is possible that the water and vinegar cannot evaporate at the same rate so the assortment will become more or less “vinegary” as the mixture fades away.

6. The molecules of the water are more attracted to the sugar cubes and molecules present on the paper than to any other water molecule. The water will portable to a stature such that the mass of water equals the force clasping it up due to the capillary action.
It might also be useful to some science experimentations with water using an Archimedes screw, that is a technique of moving water from a subordinate to an advanced level. https://www.fgsi.co.in/international-science-fairs

When a child enters to higher studies, his curiosity increases and he starts inventing the thing, he starts innovation and curiosity is the mother of innovation and if you are one of them those who are just born to be a scientist or invent things then your this journey to become a great scientist starts from right here. We have prepared a list of Science Experiments with Water which you can apply in your School Science Experiments or there are several Science Fair for Students by FGSI and many other famous event organisers held to enhance the creativity and extraordinary skill of students, you can also enrol for them.
