Winter - the best time to not just ride on the toboggan slides or play in the snow. It is also a great time for entertaining experience!
Do not believe me? But even two-three year old can learn the basics of physics, if you'll show him... an unusual experience! So, if you are willing to become a magician and professor (simultaneously) memorable.
magic bubbles
You will need: liquid soap bubbles and cocktail stick.
How it works: Choose a frosty day (this is important!) And use the wand slowly blow bubbles, leaving on a stick. After a while they zastynut. If the baby is small, it is enough to see such a miracle. A more adult child can explain that the water molecules are in constant motion. But as soon as the temperature drops below zero, they adhere to each other and form ice crystals.
Icicles Snow Queen
You will need: 2 pieces of ice coat (or other warm clothing), foil, plastic bag, paper, cloth.
Gloves, fur coat - the kid knows that all these garments warm it without giving freeze. And now you ask him, if we take two pieces of ice, one wrapped in a fur coat, and the other on a plate - which will melt faster? And even if you tell them on a plate ice melting faster, the baby still can not believe it. Therefore, an experiment.
Take two identical pieces of ice, wrapped in packages (this is done in order to not hurt the coat in the time of the experiment), one hiding in the coat, the other left on the table. When the ice melts a bit on the plate, expand the fur to see that piece of ice melts slowly in the clothes.
Children with this need to tell you that the coat acts as a cup thermos, keeping the temperature of hands, because the human body generates heat.
crystal nuggets
You will need: air bubbles, water, and salt.
Take a rubber ball and fill it with water from the tap. Put in the freezer for 6 hours to completely freezing. Remove the ball and get a nice crystal nugget. We pour a little salt on it. Under the influence of salt ice begins to melt. This experience clearly shows why winter roads and sidewalks salted.
Home geyser
You will need: water, paint, molds for ice, oil.
Take water and mix it with a paint (better to take gouache). Then, the colored water poured into cups and put in the freezer.
Ready-colored pieces of ice drop into a jar with oil. As soon as the ice will melt, colored water droplets will sink to the bottom. The experience itself is a very beautiful work. And this is another proof, the fact that water molecules are not mixed with oil molecules. Even if you try to pour in half a bottle of oil and a half of water, shake well, then oil will break into small molecules, but not mixed with water. Furthermore, food coloring is mixed only with water. He does not stain oil.
ice fishing
You will need: molds (can be in the form of fish or any other), water, and a thread bowl with water.
First, make "ice fish". Fill water (can take tinted) in molds and put in the freezer. Wait until warm. Take the container with water.
We get ice figures, tied with a thread (she immediately primerznet to it), and the rest is poured into a bowl of water. So, then, until the ice began to melt, icicles will freeze to each other, too.
It turns out this is due to the fact that the ice is very cold. Its surface temperature is below 0 degrees. And the water in the wet string from contact also with ice freezes "sticking" to a piece of ice. But this should be done quickly, while the dry ice. Once it slightly podtaet, it is covered with a thin film of water whose temperature is no longer sufficient. Merry you walks and new knowledge!
