Experiments physical reasons
It is quite difficult for a kid to understand the intricacies of physical wisdom, but some things will even be in his hands. For example, you can visually demonstrate to him some properties of water and air.
Why is there more in the water?
In a three-liter jar, plant any small insect, such as a mosquito. Tighten the neck of the jar with a food film, but do not stretch it, but on the contrary - lightly press it to make a small groove. Tie the tape with a rope and pour water into it. You will get a magnifying glass, through which you can perfectly see the smallest details of an insect.
Where does the rain come from?
Pour into a three-liter jar of a glass of boiling water. Place a few ice cubes on a baking sheet, and put it on the jar. The air inside the jar, rising upwards, will begin to cool. The water vapor contained in it forms a "cloud". When it cools, it will turn into water again - droplets will fall down, and you will get a real rain. It is the same in nature.
Can the air become more or less?
Put an empty, open plastic bottle in the refrigerator. When it cools, remove it and put a balloon on the neck. And now put this bottle in a bowl of hot water. Look, what happens to the ball? Why did he start to inflate, and even himself? The answer is simple: this air became hot, and he, expanding, comes out of the bottle!
Tiny Science
Do you think that if a child is barely two years old, is it too early for him to study science? By no means. Some experiments, which at first glance seem very simple, will help your child develop attentiveness and logic, spur his curiosity, and teach him to draw conclusions. In addition, they will prepare the baby for more difficult studies and teach him assiduity. Here, for example, several experiments with water, which are quite suitable for toddlers two or three years.
What kind of water?
Pour the water into one cup, put the ball in the other. Pay attention to the baby that the water took the form of a cup, and the ball remained round. Then pour the water into a deep bowl, put the same ball in the other. What form does water now have? And the ball? Help the crumb to draw the right conclusions and let him experiment himself, pouring water into various containers.
What is the taste of the water?
Discuss with the baby what taste his favorite dishes have, find out what he prefers: sweet or salty, and why. Now take a large bottle of water. Pour water into several cups. Suggest the kid to try: let him make sure that the water has no taste. Now pour salt into one glass, in the other - sugar, in the third drop of lemon juice. Let the kid make sure that now the water has acquired a taste. Why? How did it happen? With the help of leading questions, encourage the child to make a conclusion that the substance dissolved in water "shared" with her own taste.
What in the water will drown, and what will emerge?
This game is good to play both in summer at the cottage, and during bathing. For it you will need different items: pebbles, twigs, rubber toys, nuts. Let the baby observe what objects are drowned, and which ones will surface, and will think, why it happened exactly so. Such a simple game will teach your child to classify objects and explore them for different properties, which means that the kid will learn how to extract the necessary knowledge himself.
- Experiments biological reasons
What do plants need to grow normally? And why are they green? Perhaps, it is these questions, one of the first, that will be asked to you by a little "why". Let's try to answer them!
Ice treats
In winter, your baby probably looked with interest at the snow and ice. Perhaps a couple of icicles migrated from the street cornice home, and you and the child watched them melt. In the summer, the "ability" of water to turn into ice upon cooling can be used to make "edible" toys or ice cream of unusual shape in the form of a favorite of your crumbs from a cartoon character or a cute forest animal. From plasticine, mold a cake 2-3 cm thick. Its area should match the size of the figures that you plan to use. Take plastic figures - soldiers or beasts, press them into plasticine - you will get a great shape. The inner surface of the mold is densely covered with foil and carefully pour in the holes with a thick juice with pulp (instead of juice you can use a mixture for making ice cream or plain water). If you want to make ice cream on a stick, fasten a stick or toothpick in the form. Carefully place the form in the freezer. In the morning you will receive edible figurines from fruit ice.
- Experiments chemical kakachki
Chemistry is a complex science, but even with a reasonable approach it can become a fertile ground for satisfying your child's curiosity.
Where is the starch contained?
This is one of the most visible and safe chemical experiments. First, show the baby that white starch, when interacting with iodine, immediately turns blue-violet. And then offer the child a slice of white bread, raw potatoes and a little boiled egg white. Let your baby with a simple, but the real reagent will determine in which piece the starch is contained, and in which it does not.
