Home water experiences for children and adults

In summer, home experiences with water for children are very useful. All babies like to play and tinker in water in hot weather. Conducting such "research" allows them to become familiar with the most important properties of water. Therefore, we present them before moving on to interesting, informative, fun, visual experiences.

Water properties

Water is the basis of life. It is the “base” for the good work of the human body. There are three known states of water: liquid, gaseous and solid. Consider the following properties of water.

  1. Transparency.Take two glasses. Pour water into one, milk into the other. Give the crumbs on the bead and offer to drop it in turn in both glasses. The bead can easily be seen in a glass of water, because the water is crystal and clear.
  2. ColorlessnessTo confirm in glasses, pour water and paint it with various colors. Leave the water in one glass as colorless and transparent, that is, as it was.
  1. FlowabilityTake small plates of various sizes. Pour some water on the bottom of a small plate, and then on the bottom of a large plate. Put obstacles in the way of the stream and watch how water copes with them.
  2. Without taste and smell.Water has no taste. Make the following experience: pour water, tea, milk, juice into each of the four glasses. Close your baby's eyes, invite him to try them and describe his feelings: the juice is sour, the tea is sweet, and the water has no taste. But, of course, tasteless water has thousands of flavors and it is the most divine nectar. Water does not smell. Yes this is true. Again in glasses pour juice, lemonade, tea. Then tie the eyes of the baby and ask to find the water by smell. Baby will find it quickly and easily.
  3. The adoption of any form in which it is poured.Water does not have its own form. To make sure, pour the water into different forms: basins, jugs, small vases. It takes the form in which it was poured.Home water experiences for children and adults 2
  4. Dissolving substances.What dissolves in water? Try to dissolve different objects in cups of water: sugar, honey, salt, sand, rice, coffee, beads. It immediately becomes clear that water is not able to dissolve everything.
  5. Freezing.What is ice? This is water in solid form. And how is it formed? There are two ways. In the first case, the water is cooled to 0 ° C, so the cubes are made in the freezer. In the second case, the water vapor freezes and frost appears in the refrigerator.
  6. Evaporation.Under sunshine, water from lakes, seas, rivers, plants, the human body evaporates. Particles of vapor rise into the air, cool, turn into water droplets. They form clouds together.
  7. Expansion and contraction of water.When the water bottle freezes, it may burst as the water expands. If you lower the flask with water into cold water, it will cool and shrink.

There are objects that drown in water, and some remain on the surface and float. Dip various things into the water - pebbles, paper pieces, cones, metal, wood objects, and watch which ones drown and which ones do not.

Home water experiments

Experience 1. With ordinary paint

Take ordinary paint and drip into the water one drop at a time. Watch how it gradually mixes up. The color in the water becomes less bright. The more paint, the color becomes brighter.Home experiences with water and paint for children and adults

Experience 2. In search of treasure

Schoolchildren will be interested to make this experience. To do this, you need buttons, pebbles, tinsel, shells. Pour water into a glass and pour out the "treasure". Next, put it in the freezer. Wait for freezing water. As soon as it freezes, you begin to take out the ice piece with a spoon or forceps, and then dip it in warm water. When it starts to melt, you get “treasures”.Home experiences with water and paint for children: the search for treasure

Experience 3. Absorption of water

Pour water into the container and bring a sponge to it and watch what happens. Water, jumping up, is absorbed into the pores. Then bring different things to the water and watch what you are able to absorb and which do not have absorbing properties.

Experience 4. With ice cubes

Children 5-6 years will be interested in this experience. Freeze the ice, making them special cubes. Take thin cocktail tubules, cut them in length by 5 cm and insert into the ice form. Then put in the freezer. After freezing, you get strong cubes with a straw. True, like the ships? Attaching a sail to a match, launch ships through puddles or in a bath with water.Home experiences with water and paint for children: ships

Experience 5. "Floating" egg

Take a raw egg. Put it in a glass of water. You will see that it sinks to the bottom.Then remove the egg and dissolve 2-3 tablespoons of salt there. Dip it down again now in a glass with salty water. You will see an egg floating on a watery surface.

Hence the conclusion that the density of water increases with salt and therefore it is more difficult to drown in salt water. For example, in the Dead Sea the water is too salty, therefore, a person can lie on the sea surface and not drown.experiments with water for children: an egg

Experience 6. "Boiling" cold water

Wet and squeeze the handkerchief. Then cover them with a full glass of cold water and a rubber band and fasten a handkerchief on the glass. In the middle of the handkerchief, press your finger so that it enters the water 2-3 cm. Then turn the glass upside down over the sink. Hold the glass with one hand and with the other lightly strike the bottom. And what happens? Water begins to "boil" or seethe in a glass.

Explanation: a wet handkerchief does not let water through. Upon impact on the glass, a vacuum is formed in it and through the handkerchief air enters the water absorbed by the vacuum. These air bubbles form an opinion about the "boiling" of water.experiments with water for children: boiling

Experience 7. Disappearing water

Take two identical glasses and pour them with water to the same level. Mark it with a marker.Cover one cup with a lid and leave the other open. Put them in a warm place. The next day you will see that the water level in the open glass has become lower, and in the closed one it has not changed.

What happened? Under the influence of heat, the water in the open glass evaporated and turned into the smallest particles of steam that scattered in the air. From here a conclusion: sometime all wet dries up.

Experience 8. With ice

In a glass filled to the brim with water, lower a piece of ice. The ice will begin to melt, and water will not overflow the edge. It follows that the water into which the ice has transformed is heavier and takes up less space than ice. Conclusion: ice is lighter than water.

Experience 9. Rainbow

Show your kids a rainbow in the room. At a small angle, place a mirror in the water. Then catch a sunbeam with a mirror and point it at the wall. Rotate it until you see a spectrum of light on the wall. The role of the prism, which decomposes light into its components, is fulfilled by water. Kids will love this experience because they will see a rainbow.
