Hello friends @steemiteducation, 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.

In my last publication we made an experiment where the pressure of the water was evidenced, in the following we will do a series of experiments where we will continue studying this same concept and the one of the atmospheric pressure, they all include water for what our children will love.

So to have fun and learn at the same time!

As is usual, review the theoretical part so that the children know what it is about and what we are studying.

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. Source

Atmospheric pressure

Atmospheric pressure is the weight of the column of air over any point or place on the earth and is therefore the weight per unit area.

Atmospheric pressure = Weight of the air column / Surface unit

The higher the height, the lower the atmospheric pressure and the lower the height and the closer it gets to sea level, the greater the pressure. Source

Yes now! Let's go with the fun! Let's see what we need for our experiment.

Materials:

• A plastic pot with its lid.

• A nail or a puncturing object to open a hole in the pot

• Water

• A tray to avoid water spills

Procedures:

• We make a small hole in the plastic bottle, about half its height.

• Cover it provisionally (for example with your finger) and fill the bottle completely with water, then cover it.

• When removing the finger from the hole it is observed that no water comes out. But, when removing the cap from the bottle, we observe that a jet of water comes out of the hole.

What has happened?

By keeping the bottle with the plug on, the internal pressure on the hole (the pressure exerted by the air contained in the bottle plus the pressure exerted by the water column above the hole) is equal to the external pressure (the atmospheric pressure) This is why water does not come out of the hole.

If we remove the plug, allowing air (and atmospheric pressure) to enter through the top of the bottle, the previous balance is broken. The internal pressure on the hole (the atmospheric pressure inside the bottle plus the pressure exerted by the water column on the hole) is higher than the external pressure (the atmospheric pressure). This pressure difference drives the water out of the bottle.

As you can see the Home Experiments can be very useful when using them as a teaching and learning tool, we as parents have the responsibility to offer our children the best possible education, for which we should look for the most appropriate strategies, our little ones They are full of curiosity and they love seeing new things and that is a point in our favor, the Experiments Cases gives us a universe of our knowledge. The opportunity to learn while having fun, just do not think about it anymore and put it into practice.
