Discover science: 6 experiments with water for children
As children spontaneously investigate the properties of the physical world, they add new knowledge and understand better how science works in a practical way To motivate children to discover science, it is important to emphasize that children understand the properties of the world around them and this can only be achieved by conducting experiments like these 6 experiments with water for children.
Only through the understanding of the physical properties of air, water, soil, weather and other natural phenomena through science, will they be able in the future to solve the problems they will encounter when facing the real world .
Young children do not learn when we present something that does not interest them; they simply put it aside. Children are interested, above all, in the materials and objects that attract and attract their attention. They often carry things in their pockets that have no value: a candy, a lollipop stick, a marble, a piece of glass, a bent screw ... You have to know how to make this natural curiosity profitable by providing them with a place where they can place your treasures. For this reason, when elaborated materials are used, which "can not be touched" for an experiment, the child finds out very little, because he does not know them.
New scientific knowledge with which to experiment
By touching, manipulating, experimenting, feeling, etc., children are able to acquire all this information, broadening and deepening their understanding of the world around them. To make children scientists it is necessary to feed their curiosity. In this case, when doing experiments with water, children will obtain these benefits:
- They will expand their concepts about weight and mass when they float objects in a container of water.
- They will understand better the pressure of the air and the movement when they introduce an object inside a bowl full of water and this one overflows.
- You will get an idea of the process of the three states of water (liquid, solid and gaseous) when they try to heat it and to cool it at different temperatures.
6 experiments with water for children
1. Steam of water.This experiment has to be very watched by older people. You have to fill a pot of water halfway, putting it to boil. If you have a glass lid, we can see when it starts to boil, how water drops form. We will raise it so that the children can see the steam.
You have to explain to them that water turns into steam when it boils and into water again when it cools (those are the droplets on the lid).
2. Freezing.Fill some glasses with water and others with alcohol, putting labels on each one to know what they are. We will leave them in the freezer, attentive to remove them when the water begins to freeze. Once the water is already ice, the alcohol is not yet.
We can explain to them that for some liquids to freeze it takes much more cold than for the water to freeze; for example the antifreeze of cars.
3. Water does not fall.It is a very fun game: we fill a glass with water, and we will tell the children that we will put it face down without spilling the water. Fill three quarters of the glass and place a cardboard on it. When the glass is turned upside down, the air will keep the cardboard in place and the water will not fall.
When the glass is turned upside down, part of it is emptied. The air tries to fill that void: the pressure of the air on the paper keeps it in place.
4. Floating or sinking.We can perform several experiments with different objects, testing which float and which do not. Some, like different types of wood, float more or less: on the surface of the water, at half depth ... Other materials, such as plastics ... what happens?
We can ask them questions about why they think this is the case, telling them about the materials with which they are made.
5. It gets wet.It is now a question of children investigating the effect that water produces on different substances, when they fall on them or wet them. We can have several jars and in each one, we will put different things: a paper handkerchief, beans, sugar, oil, a nail, marble ... and fill them with water. Let the children observe what has happened.
In the case of sugar, salt, etc. we can talk to them about the concept of dissolution.
6. FrostWe are going to gather two glasses of crushed ice with another one of thick salt in a can, spinning the mixture quickly. At half an hour, on the outside of the can there will be dew. If you wait a little longer, the dew will have turned into frost.
As the can cools, the moisture in the air condenses on the cold surface. As the can gets colder, the water on the surface freezes, forming frost.
