The experiments at home, which we will talk about now, are very simple, but extremely entertaining. If your child is just getting to know the nature of various phenomena and processes, such experiences will look like magic for him. But it’s not a secret for anyone that it’s best to present complex information to children in a playful way — this will help to consolidate the material and leave vivid memories that will be useful in further education.
Explosion in still water
Discussing possible experiments at home, first of all, we will talk about how to make such a mini-explosion. You will need a large vessel filled with ordinary tap water (for example, it can be a three-liter bottle). It is advisable that the liquid settle in a quiet place for 1-3 days. After this, carefully, without touching the vessel itself, drip a few drops of ink into the very middle of the water from a height. They will sprawl beautifully in the water, as if in slow motion.
A balloon that inflates itself
This is another interesting experience that can be carried out by conducting chemical experiments at home. Pour a teaspoon of ordinary baking soda into the ball itself. Next, you need to take an empty plastic bottle and pour 4 tablespoons of vinegar into it. The ball must be pulled over its neck. As a result, soda is poured into vinegar, a reaction will occur with the release of carbon dioxide, and the ball will inflate.
Volcano
Using the same soda and vinegar, you can make a real volcano in your house! You can even use a plastic cup as a base. 2 tablespoons of soda are poured into the "vent", filled with a quarter glass of heated water and a little dark food color is added. Then it remains only to add a quarter glass of vinegar and watch the “eruption”.
"Color" magic
Home experiments that you can demonstrate to your child also include unusual changes in various substances of their color. A vivid example of this is the reaction that occurs when iodine and starch are combined. Mixing brown iodine and snow-white starch, you get a liquid ... a bright blue hue!
Fireworks
What other experiments can be done at home? Chemistry provides a huge field for activity in this regard. For example, you can make bright fireworks right in the room (but better in the yard). A little potassium permanganate must be crushed into a fine powder, and then take a similar amount of charcoal and also grind it. Thoroughly mixing the coal with manganese, add iron powder there. This mixture is poured into a metal cap (a regular thimble is also suitable) and kept in a burner flame. As soon as the composition is heated, a whole rain of beautiful sparks will begin to crumble around.
Soda rocket
And finally, let’s say again about chemical experiments at home, where the simplest and most affordable reagents are involved - vinegar and sodium bicarbonate. In this case, you need to take a plastic film cassette, fill it with baking soda, and then quickly pour 2 teaspoons of vinegar. At the next stage, you close the homemade rocket with a lid, put it on the ground upside down, move away and watch how it takes off.
