Friends, good afternoon! Agree, how sometimes it is interesting to surprise our crumbs! They have such a funny reaction to. She shows that they are ready to learn, ready to assimilate new material. The whole world opens at this moment before them and for them! And we, parents, act as real wizards with a hat, from which we “pull out” something amazingly interesting, new and very important!

What will we get out of the "magic" hat today? We have 25 there experimental experiments For children and adults. They will be prepared for babies different ages to get them interested and involved in the process. Some can be carried out without any preparation, with the help of handy tools that each of us has at home. For others, you and I will buy some materials so that everything goes smoothly for us. Well? I wish all of us good luck and forward!

Today will be real holiday! And in our program:

So let's decorate the holiday by preparing an experiment for a birthday, New Year, March 8, etc.

Ice bubbles

What do you think would happen if simple bubbles that crumble in 4 years so loves to inflate, run after them and burst them, inflate them in the cold. Or rather, right into the snowdrift.

I give you a hint:

• they will burst immediately!
• take off and fly away!
• freeze!

Whatever you choose, I say right away, it will surprise you! Can you imagine what will happen to the little one?

But in slow motion - it's just a fairy tale!

I complicate the question. Is it possible to repeat the experience in the summer in order to get a similar option?

Choose answers:

• Yes. But you need ice from the fridge.

You know, even though I so want to tell you everything, but that’s exactly what I won’t do! Let there be at least one surprise for you!

Paper vs water

We are waiting for the real experiment. Is it really possible for paper to win over water? This is a challenge for everyone who plays Rock-Paper-Scissors!

What we need:

• Paper;
• Water in a glass.

Cover the glass. It would be nice if its edges were a little wet, then the paper will stick. Gently turn the glass upside down... No water leaks!

Inflate balloons without breathing?

We have already carried out chemical children's experiences. Remember, there the very first for very small crumbs was a room with vinegar and soda. So, let's continue! And we use the energy, or rather, the air that is released during the reaction for peaceful purposes.

Ingredients:

• Soda;
• The bottle is plastic;
• Vinegar;
• Ball.

Pour soda into a bottle and pour 1/3 of vinegar. Shake lightly and quickly pull the ball over the neck. When it inflates, bandage and remove from the bottle.

Such an experience a small one will be able to show even in kindergarten.

Rain from a cloud

We need:

• Bank with water;
• Shaving foam;
• Food coloring (any color, you can use several colors).

We make a cloud of foam. Big and beautiful cloud! Leave it to the best cloud maker, your child 5 years. He will definitely make her real!

photo author

It remains only to distribute the dye over the cloud, and ... drop-drip! Rain is coming!

Rainbow

Maybe, physics children are still unknown. But after they make the Rainbow, they will definitely love this science!

• Deep transparent container with water;
• Mirror;
• Flashlight;
• paper.

Place a mirror at the bottom of the container. At a slight angle, shine a flashlight on the mirror. It remains to catch the Rainbow on paper.

Even easier is to use a disc and a flashlight.

crystals

There is a similar, only already finished game. But our experience interesting the fact that we ourselves, from the very beginning, will grow crystals from salt in water. To do this, take a thread or wire. And we will hold it for several days in such salty water, where the salt can no longer dissolve, but accumulates in a layer on the wire.

Can be grown from sugar

lava jar

If you add oil to a jar of water, it will all collect on top. It can be tinted with food coloring. But in order for the bright oil to sink to the bottom, you need to pour salt on top of it. Then the oil will settle. But not for long. The salt will gradually dissolve and “release” beautiful droplets of oil. Colored oil rises gradually, as if a mysterious volcano seething inside the jar.

Eruption

For toddlers 7 years it will be very interesting to blow up, demolish, destroy something. In a word, the real element is for them. and therefore we create a real, exploding volcano!

We sculpt from plasticine or make a “mountain” from cardboard. We put a jar inside it. Yes, so that her neck fits the "crater". We fill the jar with soda, dye, warm water and ... vinegar. And everything will begin to “explode, the lava will rush up and flood everything around!

A hole in the bag is not a problem.

This is what convinces book of scientific experiments for children and adults Dmitry Mokhov "Simple Science". And we can verify this statement ourselves! First, let's fill the bag with water. and then we pierce it. But what they pierced (a pencil, a toothpick or a pin) will not be removed. Are we running out of water? Checking!

Water that does not spill

Only such water still needs to be made.

We take water, paint and starch (as much as water) and mix. The end result is plain water. Just don't spill it!

"Slippery" egg

In order for the egg to really crawl into the neck of the bottle, it is worth setting fire to a piece of paper and throwing it into the bottle. And cover the hole with an egg. When the fire is out, the egg will slip inside.

snow in summer

This trick is especially interesting to repeat in the warm season. Remove the contents of the diapers and soak with water. All! Snow is ready! Now such snow is easy to find in the store in children's toys. Ask the seller artificial snow. And don't ruin diapers.

moving snakes

To make a moving figure, we need:

• Sand;
• Alcohol;
• Sugar;
• Soda;
• Fire.

Pour alcohol on a hill of sand and let it soak. Then pour sugar and soda on top, and set fire! Oh what a funny this experiment! Kids and adults will love what the snake comes to life!

Of course, this is for older children. Yes, and it looks pretty scary!

battery train

The copper wire, which we twist into an even spiral, will become our tunnel. How? Connect its edges, forming a round tunnel. But before that, we “launch” the battery inside, we only attach neodymium magnets to its edges. And consider yourself invented perpetual motion machine! The steam locomotive drove off.

Candle swing

To light both ends of the candle, you need to clean the bottom of it to the wick from wax. Heat the needle over the fire and pierce the candle in the middle with it. Put the candle on 2 glasses so that it rests on the needle. Burn the edges and wiggle slightly. Then the candle itself will swing.

Elephant Tooth Paste

The elephant needs everything big and much. Let's do it! We dissolve potassium permanganate in water. Adding liquid soap. The final ingredient, hydrogen peroxide, turns our mixture into giant elephant paste!

Let's drink a candle

For a greater effect, we color the water in bright color. We put a candle in the middle of the saucer. We set it on fire and cover it with a transparent container. Pour water into a saucer. At first, the water will be around the container, but then everything will soak inside, to the candle.
Oxygen is burned, the pressure inside the glass decreases and

Real chameleon

What will help our chameleon change color? Cunning! Give your toddler 6 years decorate in different colors plastic plate. And you yourself cut out the figure of a chameleon on another plate, similar in shape and size. It remains not to firmly connect both plates in the middle so that the upper one, with a cut out figure, can rotate. Then the color of the animal will always change.

Light up the rainbow

Arrange the Skittles on a plate in a circle. Pour water into the bowl. just wait a bit and get a rainbow!

smoke rings

Cut off the bottom plastic bottle. And pull the cut edge balloon ik to get a membrane like in the photo. ignite incense stick and put it in a bottle. Close the lid. When there is solid smoke in the jar, unscrew the lid and tap on the membrane. Smoke will come out in rings.

colorful liquid

To make everything look more spectacular, paint the liquid in different colors. Make 2-3 blanks of colored water. pour water of the same color into the bottom of the jar. Then carefully, along the wall with different sides pour vegetable oil. Pour water mixed with alcohol over it.

Egg without shell

Put a raw egg in vinegar for at least a day, some say for a week. And the focus is ready! An egg without a hard shell.
The egg shell is rich in calcium. Vinegar reacts actively with calcium and gradually dissolves it. As a result, the egg is covered with a film, but completely without a shell. It feels like an elastic ball to the touch.
Also, the egg will be larger than its original size, as it will absorb some of the vinegar.

Dancing little men

It's time to mess around! Mix 2 parts cornstarch with 1 part water. Put a bowl of starchy liquid on top of your speakers and turn up the bass!

Decorating the ice

We decorate ice figures of various shapes with the help, mixed with water and salt, food grade paint. Salt corrodes the ice and seeps deep, forming interesting passages. Great idea color therapy.

Launching paper rockets

We free tea bags from tea by cutting off the top. We set fire! Warm air lifts the package!

There are so many experiences that you will definitely find something to do with children, just choose! And don't forget to come back for a new article that you'll find out about if you subscribe! Invite your friends to visit us! And that's all for today! Bye!

Helpful Hints

Children are always trying to find out something new every day and they always have a lot of questions.

They can explain some phenomena, or you can show how this or that thing, this or that phenomenon works.

In these experiments, children not only learn something new, but also learn create differentcrafts with which they can play further.

1. Experiments for children: lemon volcano

You will need:

2 lemons (for 1 volcano)

Baking soda

Food coloring or watercolors

Dishwashing liquid

Wooden stick or spoon (optional)

1. cut off lower part lemon so that it can be placed on a flat surface.

2. On the reverse side, cut a piece of lemon as shown in the image.

* You can cut half a lemon and make an open volcano.

3. Take the second lemon, cut it in half and squeeze the juice out of it into a cup. This will be the backup lemon juice.

4. Place the first lemon (with the part cut out) on the tray and spoon "remember" the lemon inside to squeeze out some of the juice. It is important that the juice is inside the lemon.

5. Add food coloring or watercolor to the inside of the lemon, but do not stir.

6. Pour dishwashing liquid inside the lemon.

7. Add a full spoonful to the lemon baking soda. The reaction will start. With a stick or spoon, you can stir everything inside the lemon - the volcano will begin to foam.

8. To make the reaction last longer, you can gradually add more soda, dyes, soap and reserve lemon juice.

2. Home experiments for children: electric eels from chewing worms

You will need:

2 glasses

small capacity

4-6 chewable worms

3 tablespoons of baking soda

1/2 spoon of vinegar

1 cup water

Scissors, kitchen or clerical knife.

1. With scissors or a knife, cut lengthwise (just lengthwise - this will not be easy, but be patient) of each worm into 4 (or more) parts.

* The smaller the piece, the better.

* If scissors don't want to cut properly, try washing them with soap and water.

2. Mix water and baking soda in a glass.

3. Add pieces of worms to the solution of water and soda and stir.

4. Leave the worms in the solution for 10-15 minutes.

5. Using a fork, transfer the worm pieces to a small plate.

6. Pour half a spoon of vinegar into an empty glass and start putting worms in it one by one.

* The experiment can be repeated if the worms are washed plain water. After a few attempts, your worms will begin to dissolve, and then you will have to cut a new batch.

3. Experiments and experiments: a rainbow on paper or how light is reflected on a flat surface

You will need:

bowl of water

Clear nail polish

Small pieces of black paper.

1. Add 1-2 drops to a bowl of water clear varnish for nails. See how the varnish disperses through the water.

2. Quickly (after 10 seconds) dip a piece of black paper into the bowl. Take it out and let it dry on a paper towel.

3. After the paper has dried (it happens quickly) start turning the paper and look at the rainbow that is displayed on it.

* To better see the rainbow on paper, look at it under the sun's rays.

4. Experiments at home: a rain cloud in a jar

When small drops of water accumulate in a cloud, they become heavier and heavier. As a result, they will reach such a weight that they can no longer remain in the air and will begin to fall to the ground - this is how rain appears.

This phenomenon can be shown to children with simple materials.

You will need:

Shaving foam

Food coloring.

1. Fill the jar with water.

2. Apply shaving foam on top - it will be a cloud.

3. Let the child begin to drip food coloring onto the "cloud" until it starts to "rain" - drops of food coloring begin to fall to the bottom of the jar.

During the experiment, explain this phenomenon to kid.

You will need:

warm water

Sunflower oil

4 food coloring

1. Fill the jar 3/4 full with warm water.

2. Take a bowl and mix 3-4 tablespoons of oil and a few drops of food coloring in it. IN this example 1 drop of each of 4 dyes was used - red, yellow, blue and green.

3. Stir the dyes and oil with a fork.

4. Carefully pour the mixture into a jar of warm water.

5. Watch what happens - the food coloring will begin to slowly sink through the oil into the water, after which each drop will begin to disperse and mix with other drops.

* Food coloring dissolves in water, but not in oil, because. oil density less water(which is why it "floats" on water). A drop of dye is heavier than oil, so it will begin to sink until it reaches the water, where it begins to disperse and look like a small firework.

6. Interesting experiences: ina bowl in which colors merge

You will need:

- a printout of the wheel (or you can cut out your own wheel and draw all the colors of the rainbow on it)

Elastic band or thick thread

Glue stick

Scissors

A skewer or screwdriver (to make holes in the paper wheel).

1. Choose and print the two templates you want to use.

2. Take a piece of cardboard and use a glue stick to glue one template to the cardboard.

3. Cut out the glued circle from the cardboard.

4. TO reverse side glue the second template on the cardboard circle.

5. Use a skewer or screwdriver to make two holes in the circle.

6. Pass the thread through the holes and tie the ends into a knot.

Now you can spin your spinning top and watch how the colors merge on the circles.

7. Experiments for children at home: jellyfish in a jar

You will need:

Small transparent plastic bag

Transparent plastic bottle

Food coloring

Scissors.

1. Lay the plastic bag on a flat surface and smooth it out.

2. Cut off the bottom and handles of the bag.

3. Cut the bag lengthwise on the right and left so that you have two sheets of polyethylene. You will need one sheet.

4. Find the center of the plastic sheet and fold it like a ball to make a jellyfish head. Tie the thread around the "neck" of the jellyfish, but not too tight - you need to leave a small hole through which to pour water into the head of the jellyfish.

5. There is a head, now let's move on to the tentacles. Make cuts in the sheet - from the bottom to the head. You need about 8-10 tentacles.

6. Cut each tentacle into 3-4 smaller pieces.

7. Pour some water into the jellyfish's head, leaving room for air so the jellyfish can "float" in the bottle.

8. Fill the bottle with water and put your jellyfish in it.

9. Drop a couple of drops of blue or green food coloring.

* Close the lid tightly so that water does not spill out.

* Have the children turn the bottle over and watch the jellyfish swim in it.

8. Chemical experiments: magic crystals in a glass

You will need:

Glass cup or bowl

plastic bowl

1 cup Epsom salt (magnesium sulfate) - used in bath salts

1 cup hot water

Food coloring.

1. Pour Epsom salt into a bowl and add hot water. You can add a couple of drops of food coloring to the bowl.

2. Stir the contents of the bowl for 1-2 minutes. Most of the salt granules should dissolve.

3. Pour the solution into a glass or glass and place it in the freezer for 10-15 minutes. Don't worry, the solution isn't hot enough to crack the glass.

4. After freezing, move the solution to the main compartment of the refrigerator, preferably on the top shelf and leave overnight.

The growth of crystals will be noticeable only after a few hours, but it is better to wait out the night.

This is what the crystals look like the next day. Remember that crystals are very fragile. If you touch them, they are most likely to break or crumble immediately.

for discovering this beauty. Thanks for the inspiration and goosebumps.
Join us at Facebook And In contact with

There are very simple experiences that children remember for a lifetime. The guys may not fully understand why this is all happening, but when time will pass and they will find themselves in a lesson in physics or chemistry, a very clear example will surely pop up in their memory.

website collected 7 interesting experiments that children will remember. Everything you need for these experiments is at your fingertips.

refractory ball

It will take: 2 balls, candle, matches, water.

Experience: Inflate a balloon and hold it over a lighted candle to show the children that the balloon will burst from fire. Then pour plain tap water into the second ball, tie it up and bring it to the candle again. It turns out that with water the ball can easily withstand the flame of a candle.

Explanation: The water in the balloon absorbs the heat generated by the candle. Therefore, the ball itself will not burn and, therefore, will not burst.

Pencils

You will need: plastic bag, simple pencils, water.

Experience: Pour water halfway into a plastic bag. We pierce the bag through with a pencil in the place where it is filled with water.

Explanation: If you pierce a plastic bag and then pour water into it, it will pour out through the holes. But if the bag is first filled halfway with water and then pierced sharp object so that the object remains stuck in the bag, then almost no water will flow out through these holes. This is due to the fact that when polyethylene breaks, its molecules are attracted closer friend to friend. In our case, the polyethylene is pulled around the pencils.

Non-popping ball

You will need: balloon, wooden skewer and some dishwashing liquid.

Experience: Lubricate the top and bottom with the product and pierce the ball, starting from the bottom.

Explanation: The secret of this trick is simple. In order to save the ball, you need to pierce it at the points of least tension, and they are located at the bottom and at the top of the ball.

Cauliflower

It will take: 4 glasses of water, food colorings, cabbage leaves or white flowers.

Experience: Add food coloring of any color to each glass and put one leaf or flower into the water. Leave them overnight. In the morning you will see that they have turned into different colors.

Explanation: Plants absorb water and thus nourish their flowers and leaves. This is due to the capillary effect, in which the water itself tends to fill the thin tubes inside the plants. This is how flowers, grass, and large trees feed. By sucking in tinted water, they change their color.

floating egg

It will take: 2 eggs, 2 glasses of water, salt.

Experience: Gently place the egg in a glass with a simple clean water. As expected, it will sink to the bottom (if not, the egg may be rotten and should not be returned to the refrigerator). Pour into the second glass warm water and stir in it 4-5 tablespoons of salt. For the purity of the experiment, you can wait until the water cools down. Then dip the second egg into the water. It will float near the surface.

Explanation: It's all about density. Average density eggs are much larger than plain water, so the egg sinks down. And the density of the saline solution is higher, and therefore the egg rises.

crystal lollipops

It will take: 2 cups water, 5 cups sugar, wooden sticks for mini skewers, thick paper, transparent glasses, saucepan, food coloring.

Experience: In a quarter cup of water, boil sugar syrup with a couple of tablespoons of sugar. Sprinkle some sugar on paper. Then you need to dip the stick in syrup and collect the sugar with it. Next, distribute them evenly on a stick.

Leave the sticks to dry overnight. In the morning, dissolve 5 cups of sugar in 2 cups of water on fire. You can leave the syrup to cool for 15 minutes, but it should not cool down much, otherwise the crystals will not grow. Then pour it into jars and add different food colors. Lower the prepared sticks into a jar of syrup so that they do not touch the walls and bottom of the jar, a clothespin will help with this.

Explanation: As the water cools, the solubility of sugar decreases, and it begins to precipitate and settle on the walls of the vessel and on your stick with a seed of sugar grains.

lit match

Need: Matches, flashlight.

Experience: Light a match and hold it at a distance of 10-15 centimeters from the wall. Shine a flashlight on the match and you will see that only your hand and the match itself are reflected on the wall. It would seem obvious, but I never thought about it.

Explanation: Fire does not cast shadows, as it does not prevent light from passing through it.
