Every child loves bright colors and explosions - so why do not parents benefit from it?
1. Painted flowers
Show the children the work of the conducting system of plants with the help of flowers. To do this, prepare several solutions with different food colors and bright white flowers (carnations, gerberas or chrysanthemums). Put the flowers in the cans with the dye solution and observe the changes in the color of the petals. Already within 30-40 minutes on them will appear a border, and after 12-14 hours the flower will be painted completely.
Bonus: you will have beautiful, but very strange flowers in the room.
2. Elastic Egg
Demonstrate to children a chemical reaction using the example of a conventional raw egg. To do this, put the egg in a jar and pour it with vinegar. Acetic acid will react with calcium carbonate, the main component of the shell, so it will begin to dissolve. After a day, you need to change the vinegar in the jar, and after 48 hours, when the whole shell "melt", the egg should be thoroughly washed. The membrane is compacted under the influence of acetic acid, resulting in such an elastic and unusual egg. You can even press it with your finger.
3. Make a lava effect with an alka-seltzer
Fill the transparent vase (or usual plastic bottle) with oil for 2/3 of the volume. Add water so that 1-2 cm of air space remain on top, and add 5 drops of food coloring. Throw in the vase ¼ of the Alka-Seltzer tablet. The bubbles that secrete the tablet during the chemical reaction between soda and citric acid mix oil and water, forming a "lava".
4. Blow the balloon with candy
Sweets-pops contain a small amount of compressed carbon dioxide. And if you pour the whole package into a balloon and put it on the neck of a bottle of soda, then under the influence of carbon dioxide the balloon will inflate on its own.
5. Melting ice
Children will certainly appreciate this colorful and simple experiment. In advance, make ice in different containers and give the children salt of coarse grinding. Let them try to sprinkle ice with salt and see the process of melting with their own eyes. And now dilute in water some food colorings or usual water-color, give to children pipettes or syringes and paint the melting ice. The paint will emphasize the tunnels and crevices that form on the surface under the influence of salt.
6. Grow a big marmalade bear
Marmalade is a porous material, therefore under influence of water your bear can grow in 2 times. Here's a picture you can see the next morning, just putting a marmalade bear in a glass of water from the evening.
7. Work with watercolor textures
Do on paper a few strokes of watercolor and start experimenting with media. Drink alcohol, sprinkle salt, run blotting paper or wax pencil, rub it with sandpaper and carefully study the resulting textures.
8. Brilliant explosion
Pour 2-3 tablespoons of soda into a transparent vase, add 5-6 drops of food coloring or watercolor and fill 1-2 teaspoons of spangles. Quickly pour in ½ cup of vinegar and watch while enjoying the colorful spectacle of bubbling glitter.
9. Throw raisins in soda
In ordinary water raisins will drown, but in soda it will float, smoothly sinking downwards and rising upwards.
Bonus: you can make a splash in an adult party, repeating this trick with a glass of champagne.
10. Rain clouds from shaving cream
Fill a transparent jar with ¾ volume with water and squeeze out the shaving cream so that it completely covers the surface of the water. And now, drop the "cloud" with water and dye and watch the colored rain.
11. Frozen soap bubbles
In cold weather, go out with the children to the street and grab the soap bubble liquid. Such beauty is difficult to describe in words!
12. Bean sprout
Use transparent boxes from under the old CD to observe how the plants germinate. It is better to use beans for this purpose.
