Hello friends Hive, the education of our children is fundamental for us as parents and that is why we always have to look for the best teaching tools that help us transmit knowledge in a practical and fun way. The experiments at home are a very valuable tool that we have to take advantage of, they offer us infinite possibilities that we must use to teach.

Today we will be doing a fun experiment that children will love because it involves water and what child does not like to play with water? They will learn about the water pressure and how it varies depending on the depth.

So let's go with the experiment let's see what is needed!

But first let's review the theory a little so that our little ones know what we are talking about.

Principle of Hydrostatic:

The fundamental principle of hydrostatics states that the pressure exerted by the water depends on the depth. The deeper, the more pressure.

Materials:

• A plastic pot with its lid.

• A nail to open the holes.

• A container where the water will fall and not wet everything.

• Artificial coloring (optional)

Procedures:

1st Part of the experiment:

• To make our experiment we make two small holes at different heights in a plastic bottle. Then we filled the bottle with colored water. It is observed that the water comes out through the two holes, perpendicular to the surface of the bottle and with greater speed through the hole that is closer to the base of the bottle. The water outlet velocity decreases as the water level in the bottle decreases.

Second part of the Experiment:

• Now fill the bottle with water and put the cap. We can see that air enters through the upper hole and water comes out through the lower hole. The water comes out with constant speed while the water level inside the bottle is above the upper hole. Then, when the upper hole exceeds the water level, the speed of the water jet output decreases when the water level in the bottle decreases.

What happened?

The fundamental principle of hydrostatics states that the pressure exerted by the water depends on the depth. The deeper, the more pressure.

In the first part of the experiment the water comes out more quickly through the hole that is closer to the base at greater depth. The pressure on the hole and the speed of the water outlet decreases as the level of water inside the bottle decreases.

In the second part of the experiment, the air that enters the upper hole exerts pressure that compensates for the pressure drop of the water when losing height. The pressure on the lower hole is kept constant and the water comes out with constant velocity. Then, when the level of the water in the bottle is below the upper hole, the air enters freely through the upper hole and the rate of water exit decreases as the water inside the bottle falls.

Children love to do experiments. With them, while they have fun, they learn and ask questions about the world around them. Among its many benefits, scientific exploration, feeding, the child's natural curiosity, encouragement, stimulation, reasoning and logic, improving the ability to solve problems, improving self-esteem and preparing for understanding , understanding, understanding. Future It is not necessary to enjoy science to have a laboratory, be surprised by the amount of experiments that can be done with some materials made at home. So there's nothing else, get in touch with work and have fun with your children or students. I hope this article has been of interest and help, and I hope in my next post.
