"Young fireman" (experiments with children on fire safety). Ten fun experiments with fire Launching paper rockets

And get to know with them world and wonders of physical phenomena? Then we invite you to our "experimental laboratory", in which we will tell you how to create simple, but very interesting experiments for children.


Egg experiments

Egg with salt

The egg will sink to the bottom if you put it in a glass of plain water, but what happens if you add salt? The result is very interesting and can visually show interesting density facts.

You will need:

  • Salt
  • Tumbler.

Instruction:

1. Fill half the glass with water.

2. Add a lot of salt to the glass (about 6 tablespoons).

3. We interfere.

4. We carefully lower the egg into the water and observe what is happening.

Explanation

Salt water has a higher density than regular tap water. It is the salt that brings the egg to the surface. And if you add fresh salt water to the existing salt water, then the egg will gradually sink to the bottom.

Egg in a bottle


Did you know that a boiled whole egg can be easily bottled?

You will need:

  • A bottle with a neck diameter smaller than the diameter of the egg
  • Hard boiled egg
  • Matches
  • some paper
  • Vegetable oil.

Instruction:

1. Lubricate the neck of the bottle with vegetable oil.

2. Now set fire to the paper (you can just have a few matches) and immediately throw it into the bottle.

3. Put an egg on the neck.

When the fire goes out, the egg will be inside the bottle.

Explanation

The fire provokes the heating of the air in the bottle, which comes out. After the fire goes out, the air in the bottle will begin to cool and contract. Therefore, a low pressure is formed in the bottle, and the external pressure pushes the egg into the bottle.

The balloon experiment


This experiment shows how rubber and orange peel interact with each other.

You will need:

  • Balloon
  • Orange.

Instruction:

1. Blow up the balloon.

2. Peel the orange, but don't throw away the orange peel.

3. Squeeze the orange peel over the balloon, after which it will burst.

Explanation.

Orange peel contains limonene. It is able to dissolve rubber, which is what happens to the ball.

candle experiment


An interesting experiment showing burning a candle in the distance.

You will need:

  • regular candle
  • Matches or lighter.

Instruction:

1. Light a candle.

2. Extinguish it after a few seconds.

3. Now bring the burning flame to the smoke coming from the candle. The candle will start burning again.

Explanation

The smoke rising from an extinguished candle contains paraffin, which quickly ignites. The burning vapors of paraffin reach the wick, and the candle begins to burn again.

Vinegar Soda


A balloon that inflates itself is a very interesting sight.

You will need:

  • Bottle
  • A glass of vinegar
  • 4 teaspoons of soda
  • Balloon.

Instruction:

1. Pour a glass of vinegar into the bottle.

2. Pour the soda into the bowl.

3. We put the ball on the neck of the bottle.

4. Slowly put the ball vertically, while pouring soda into a bottle of vinegar.

5. Watching the balloon inflate.

Explanation

When baking soda is added to vinegar, a process called soda quenching takes place. During this process, carbon dioxide is released, which inflates our balloon.

invisible ink


Play with your child as a secret agent and create your invisible ink.

You will need:

  • half a lemon
  • The spoon
  • A bowl
  • Cotton swab
  • White paper
  • Lamp.

Instruction:

1. Squeeze some lemon juice into a bowl and add the same amount of water.

2. Dip a cotton swab into the mixture and write something on the white paper.

3. Wait for the juice to dry and become completely invisible.

4. When you're ready to read the secret message or show it to someone else, heat the paper by holding it close to a light bulb or fire.

Explanation

Lemon juice is organic matter, which oxidizes and turns brown when heated. Diluted lemon juice in water makes it hard to see on paper, and no one will know there's lemon juice in it until it's warmed up.

Other substances which work in the same way:

  • Orange juice
  • Milk
  • onion juice
  • Vinegar
  • Wine.

How to make lava


You will need:

  • Sunflower oil
  • Juice or food coloring
  • Transparent vessel (can be a glass)
  • Any effervescent tablets.

Instruction:

1. First, pour the juice into a glass so that it fills about 70% of the volume of the container.

2. Fill the rest of the glass with sunflower oil.

3. Now we are waiting for the juice to separate from the sunflower oil.

4. We throw a pill into a glass and observe an effect similar to lava. When the tablet dissolves, you can throw another one.

Explanation

The oil separates from the water because it has a lower density. Dissolving in the juice, the tablet releases carbon dioxide, which captures parts of the juice and lifts it up. The gas is completely out of the glass when it reaches the top, and the juice particles fall back down.

The tablet hisses due to the fact that it contains citric acid and soda (sodium bicarbonate). Both of these ingredients react with water to form sodium citrate and carbon dioxide gas.

Ice experiment


At first glance, you might think that the ice cube, being on top, will eventually melt, due to which it should cause the water to spill, but is it really so?

You will need:

  • Cup
  • Ice cubes.

Instruction:

1. Fill the glass with warm water up to the rim.

2. Lower the ice cubes carefully.

3. Watch the water level carefully.

As the ice melts, the water level does not change at all.

Explanation

When water freezes, turning into ice, it expands, increasing its volume (which is why even heating pipes can burst in winter). Water from melted ice takes up less space than the ice itself. So when the ice cube melts, the water level stays about the same.

How to make a parachute


find out about air resistance making a small parachute.

You will need:

  • Plastic bag or other lightweight material
  • Scissors
  • A small load (perhaps some figurine).

Instruction:

1. Cut out a large square from a plastic bag.

2. Now we cut the edges so that we get an octagon (eight identical sides).

3. Now we tie 8 pieces of thread to each corner.

4. Don't forget to make a small hole in the middle of the parachute.

5. Tie the other ends of the threads to a small load.

6. Use a chair or find high point to launch the parachute and check how it flies. Remember that the parachute should fly as slowly as possible.

Explanation

When the parachute is released, the load pulls it down, but with the help of the lines, the parachute occupies a large area that resists the air, due to which the load slowly lowers. The larger the surface area of ​​the parachute, the more this surface resists falling, and the slower the parachute will descend.

A small hole in the middle of the parachute allows air to flow slowly through it, rather than flopping the parachute to one side.

How to make a tornado


Find out, how to make a tornado in a bottle with this fun science experiment for kids. The items used in the experiment are easy to find in everyday life. Made homemade mini tornado much safer than the tornado that is shown on television in the steppes of America.

All children, without exception, love mysterious, mysterious and unusual phenomena. Most of the guys really like to spend interesting experiences, some of which are not seeking help from parents or other adults.

Experiments that can be done with children

Not all experiences are suitable for children. Some of them can be a danger to the life and health of babies, especially preschool age. However, under the control and supervision of parents or other adults, a child can conduct any entertaining experiment - the main thing is to carefully monitor compliance with the necessary safety requirements.

All scientific experiments are extremely useful for children. They allow young inventors to visually get acquainted with the properties of various substances and objects, chemical compounds and much more, understand the causes of certain phenomena and gain valuable practical experience that can be applied in later life. In addition, some of these experiments can be shown as tricks, thanks to which the child will be able to gain authority among his friends and buddies.

Water experiments for children

All people in everyday life very often use water and do not think at all that it has truly magical and amazing properties. Meanwhile, with this liquid you can spend incredibly with children. For example, boys and girls at home can do the following experiments:


Experiments with fire for children

You should be especially careful with fire, but it is with it that you can put incredibly interesting experiments for children. Try one of the following experiments with your offspring:



Salt experiments for children

Entertaining experiments for children can also be carried out with bulk substances, for example, with salt. Children will definitely enjoy such experiments as:



Experiments with soda for children

No less spectacular experiments for children can be carried out with baking soda, For example, "Volcano". Place a small plastic bottle on the table and mold a clay or sand volcano around it. Pour 2 tablespoons of baking soda into a container, add about 50-70 ml of warm water, a few drops of red food coloring, and at the very end - a quarter cup of vinegar. A real volcanic eruption will happen before your eyes, and the child will be delighted.


Other experiments for children with baking soda can be built on the property of this substance to crystallize. To obtain crystals, You can use the same method as in the case of salt. To do this, it is necessary to prepare a dense soda solution in which the bulk substance no longer dissolves, and then place a metal wire or other object there and leave it for several days in a warm place. The result will not be long in coming.


Balloon experiments for kids

Often experiments and experiments for children are associated with various properties of balloons, such as:



Experiments with eggs for children

Some interesting experiments with children can be done using chicken eggs, For example:



Experiments with lemon for children

Anything can be used to conduct experiments. Interesting experiments with lemon deserve special attention, for example:



Experiments with paints for children

All kids love to draw, but it will be even more interesting for them to spend entertaining experiences with paints. Try one of the following experiments:



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 experimental experiments there 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 a real holiday! And in our program:


So let's decorate the holiday by preparing an experiment for 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;
  • Lamp;
  • 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 warm time of the year. 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 cheerful 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 a 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 greater effect, we paint the water in a 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 stretch the edge of the cut balloon to get a membrane, as in the photo. Light the incense stick and place it in the 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 pour vegetable oil along the wall from different sides. 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 of food paint mixed with water and salt. Salt corrodes the ice and seeps deep, forming interesting passages. Great idea for 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! Till!

Good evening to everyone who visited my page!

In November, in my group, a project of activities with older children on life safety was held on the topic "Security. Alone at home". One of the tasks of the project was devoted to the basics fire safety, the skills of conscious, safe behavior, the creation of conditions for the assimilation and consolidation of children's knowledge about the rules of fire safety.

In the course of our activity, we carried out a number of experiments with fire.

Experiment one:

When we lit the candles, we saw that the light was bright, beautiful, and attracted attention. They found out whether it was possible to touch him, and explained why it was impossible. They concluded that fire is a bright, attractive element, but at the same time very dangerous.


Experiment two:

They remembered how to put out a fire when it becomes dangerous - with water, sand, earth, snow.

I proposed to test the correctness of children's statements with the help of experience. In our laboratory, containers store material that can be used to extinguish a fire. (except snow of course).



Conducted experience: offered to spill some water on a burning candle.


See what happened and why. They concluded that the fire went out because he was afraid of water.


Experiment Three, fourth, fifth:

Similar experiments were carried out with other materials: sand











Experiment six:

She offered to cover the burning candle tightly with a container.


Offered to see what happens fire. After a while, they saw that the fire had gone out.



They concluded that when the access of air to the container stopped, the fire went out. This means that windows cannot be opened in case of fire.

Thank you for your attention!

"Fire is a good servant, but a bad master"

Developed by an educator without a qualification category secondary special education of a municipal state preschool educational institution Kindergarten No. 23 "Bell" of the village of Ladovskaya Balka, Krasnogvardeisky district, Stavropol Territory

Zakharevich Anastasia Olegovna

2013

Goals : with the help of experiments to acquaint children with some properties of fire; develop the ability to observe, draw conclusions; to cultivate a sense of responsibility, caution; develop the ability to purposefully observe, investigate, give a correct assessment of objects and phenomena in the process of elementary experimental activity.

Equipment: metal tray, candles,a strip of paper, a piece of cotton wool, a wooden stick, a piece of cloth, a coin, tweezers, a glass of water, an empty glass, jars of sand, earth, powder.

Stroke:

(The teacher has a bandaged finger).

Educator: Hello guys, want to know what happened to my finger. Now I will tell you. Wandering around the Internet, I saw how one laboratory assistant ... do you know who a laboratory assistant is? This is a person who works in a laboratory and conducts experiments and experiments ... and so, I saw how one laboratory assistant conducts experiments with fire. I decided to repeat them, but I completely forgot about safety and inadvertently burned my finger. After that, I didn't experiment. Can you help me with these experiments? Are you afraid of getting hurt? Well, in order to avoid injuries, let's repeat the rules for handling fire, the cartoon will help us with this ...

Educator: What is this cartoon about?

Children: About the rules of conduct during a fire, if you are at home alone.

Educator: What fire safety rules are shown in the cartoon?

Children: (children's answers).

Educator: Well done boys! We remembered the basic fire safety rules and now we can conduct our experiments.

Experience number 1.

(The teacher on a metal tray lights candles)

Educator: When we lit the candles, what did we see?

Children: Light.

Teacher: What is he?

Children: He is bright and handsome.

Educator: Do you think it's possible to touch it?

Children: No.

Educator: Explain why?

Children: You can get burned. If you accidentally drop a candle on the carpet or on the floor, a fire may occur.

Educator: Who wants to “touch” the light? (If there are no volunteers, the teacher takes the child’s hand in his palm and performs actions together. Children comment on the actions performed and make sure from their own experience that the fire is hot and cannot be touched).

Educator: Yes, indeed, fire is a bright, attractive element, but at the same time very dangerous.

Physical minute:

"Campfire Flame"

to the music "bonfire sounds"

The fire has just been born, it is still weak and not confident; the children squat down, head on their knees, arms along the body.

The fire is gaining strength, growing. Slowly we rise, hands move from side to side, rise above the head.

His tongues sway from side to side, starting his fiery dance Arbitrary movements of his hands.

Tongues of flame rise higher, then fall lower, then begin to spread along the ground.

Did you enjoy being lights?

Experience number 2.

Educator: Now we will see how quickly objects from different materials light up.

The teacher brings a strip of paper to the candle flame - it quickly lights up. Then he brings cotton wool to the flame - it flares up instantly, a piece of cloth - it burns. The tree lights up more slowly than paper and cotton wool, but also burns out completely. The teacher brings a coin to the fire - it does not burn, but it gets very hot (when lowered into a glass of water, it hisses).

The teacher leads the children to make their own conclusions:

Children: Experience shows that cotton wool, paper, fabric ignite most quickly. The tree is on fire too. Metal objects do not burn, but are dangerous when heated strongly (you can get badly burned).

Experience number 3.

Educator: If the fire becomes dangerous, how can a person deal with it?

Children: It needs to be extinguished.

Educator: What is fire afraid of?

Children: Water, snow, sand, earth.

caregiver : And let's check the correctness of your statements. I have prepared the material that is used to extinguish the fire. Do you recognize them?

Children: Yes.

Educator: Let's conduct an experiment: pour some water on a burning candle. (The child follows the instructions of the teacher) What is happening and why?

Children: The fire went out because he is afraid of water.

Similar experiments are carried out with other materials: sand, earth, washing powder.

Experience No. 4

Educator: And now we will carry out the last experiment and draw the appropriate conclusions. We will tightly cover the burning slash with a glass flask. What happens to fire?

Children: It's off.

Educator: Why did our light go out after a while? I'll give you a hint: fire cannot exist without air. Therefore, when the access of air to the flask ceased, the fire went out.
