Six Simple Science Experiences To Show Every Child

Six Simple Science Experiences To Show Every Child

All children dream of becoming schoolchildren, but the truth is that over the years, for various reasons, interest in learning weakens for many. When it comes to writing school and student papers, comes to the rescue. However, parents can do to ensure that their children learn with great desire and interest. One of the most effective ways is to show kids interesting science experiments that can even be done at home.

1. Refractory ball

Refractory ball

It takes two balls, a candle and water. We inflate the first balloon and bring it to the candle, thereby demonstrating how it bursts due to the high temperature. After that, pour water into the second ball and bring it to the candle. The water ball does not burst. The explanation is very simple - water absorbs almost all the incoming heat from the fire.


2. Porcupine


You will need water, a plastic bag, and some pencils. Pour water into half of the package and isolate the air access. After that, we pierce the bag with pencils in places where it is filled with water and we see that the liquid does not flow out. This is due to the fact that, due to the pressure, the polyethylene molecules are compressed more densely, in this case - with the surface of the pencil. If you pierce the bag first, and then pour water, it will flow out.


3. "Cauliflower"

We take four glasses of water, food coloring and four white flowers, or four cabbage leaves. We mix the dyes with water, and then insert the leaves into the glasses. Very soon we will see how the plants will color in the color of dyes due to the capillary effect.



4. Floating and non-floating eggs

 We need two eggs, two glasses of water and salt. Pour plain water into one glass, and warm water into the second, then pour salt into it and stir. We wait until the water cools down, after which we put one egg in each glass. In a glass of clean water, the egg will fall to the bottom due to the fact that its density is higher than the density of water. The egg should float in a glass of brine, as the density of the water and salt is higher. If the egg floats in a glass of clean water, then it is rotten and should be thrown away.

5. Lighting a match

We take and light a match, after which we bring it to the wall at a distance of 5 cm and begin to illuminate it with a flashlight. What do we see? Only a shadow from a hand and a match, but not from fire. It is quite obvious that fire allows light to pass through, rather than obstructing its passage. Simple, but curious nonetheless.

6. Crystals

Growing crystals will require water, sugar, clear vessels, food coloring, a saucepan, sticks, and heavy paper. To begin with, cook sugar syrup in a quarter of a glass. After that, pour a couple of tablespoons of sugar onto the paper. Dip the stick in syrup, and then collect the sugars from the paper. Distribute the collected sugar evenly over the stick.

After all this, we leave the sticks with sugar to dry overnight. In the morning, dissolve 5 glasses of sugar in hot water in 2 glasses of water. We wait 15 minutes for the resulting syrup to cool down (just not to the end!). Pour the syrup into jars and mix it with dyes. We lower the blank sticks into the resulting substance so that they do not touch the walls and bottom of the vessel.

After some time, when the sugar in the syrup has cooled, its ability to dissolve will weaken, and it will settle as a sediment on the walls of the cans and on a stick. The resulting treats can be safely eaten if food coloring has been used.
