Water with magical flowers, magical water flower principle

The duct transports water and other substances upward, and the sieve tube transports nutrients to various tissues and organs.

**The result is:

The first flower destroys the duct and cannot be transported, remaining white.

The second flower changes color.

Addendum: Are you engaged in scientific research? It's all like this, first make a hypothesis based on the experiment, and then the experiment confirms whether the hypothesis is correct or not!!

This kind of biological experiment can be solved according to theoretical knowledge, and the experiment is for you to do, okay!! The purpose of this test is to allow you to analyze and solve the problem based on what you have learned, and then prove that you can't do anything amazing in this test, because you have already made a terrible classic!!

1.Prepare three cups of water and add different pigments each.

2.Prepare two white flowers, carefully cut the stem of one flower under the flower head, and trim the stem and root of the other flower.

3.Put the two stems of the flower with the cut flower stem into two cups of water of different colors, and put the other flower in the third cup.

4.Put the flowers in a warm room. After an hour, they begin to change color, and the water that absorbs the color moves up the stem to the petals.

5.Filmed the research process and recorded the observed phenomena.

My recording ducts carry water and other substances upwards, and sieves transport nutrients to various tissues and organs.

Question addendum: Give me a good experiment, don't give me **. Guess.

Give me a good experiment, don't give me **. Guess.

Why such a tone?

After 1 hour, the color begins to change.

1. The magic principle of flowers in water: "capillary phenomenon", because paper is composed of many plant fibers, and the gaps between the fibers are extremely small, forming countless tiny capillaries. After the paper and water come into contact, the water will quickly infiltrate into the gaps of the paper, changing the tension and shape of the paper, so the phenomenon of flower rulers blooming in water is formed.

2. The capillary is inserted into the infiltrated liquid, the liquid level in the tube rises, higher than the outside of the tube, the capillary is inserted into the non-infiltrated liquid, and the liquid in the tube descends and is lower than the phenomenon outside the tube, which is called capillary phenomenon.

This phenomenon is called the "capillary phenomenon", and the scientific principle is that paper is composed of many plant fibers, and the gaps between the fibers are extremely small, forming countless tiny capillaries. After the paper and water come into contact, the water will quickly infiltrate into the gaps of the paper, changing the tension and shape of the paper, so the phenomenon of flowers blooming in the water is formed.

Experimental method: 1. Choose your favorite colored pen to draw a few flowers with 5-7 petals of the same size on the paper, and then decorate some patterns or paint beautiful colors on the petals, and cut them out with scissors.

2. Fold the petals of the paper flower in order one petal to the middle, and be sure to fold them in order! Finally, fold into a bud shape, and do not press the crease too hard.

3. Use a small basin to connect an appropriate amount of warm water.

4. Gently place the folded buds on the water surface, and do not throw them directly into the water.

5. Observe the flowers in the water, and after a while, you can see the vertical foundation to the petals blooming one by one.

The most magical flowers are mimosa, dancing grass, mountain lotus leaves, longevity flower chameleon, bicolor jasmine, leaf flowers, etc., mountain lotus leaves are very magical flowers, its petals are usually pure white, but after the rain will become transparent, like borneol, sometimes you can see the meridians and lines on the petals, so it is human.

The nature is magnificent and magnificent, and there are no wonders, in addition to creating a beautiful landscape of ingenuity, it has also successfully given birth to a variety of animals and plants, some of which look more magical and make people sigh and praise.

The most amazing flowers are mimosa, dancing grass, mountain lotus leaf, longevity flower chameleon, bicolor jasmine, leaf flowers, etc.

Clause.

1. Mountain lotus leaves

In summer, we will see a magical flower, its petals are usually pure white, but after the rain will become transparent, like borneol, sometimes you can see the meridians and lines on the petals, so it is called "skeleton flower", it also has a more widely known name, is mountain lotus leaf.

Clause.

2. Mimosa

Mimosa, also known as induction grass, contains some special components in the body, which can react strongly to light, heat and other factors, that is, once touched by external forces, their leaves will immediately close tightly.

Clause.

3. Dancing grass

Dancing grass is also called windless automatic grass, the small leaves on its side, with the change of temperature, light, sound waves, natural rhythm, rotation and jumping, showing a graceful dance, usually the temperature is greater than or equal to 22, and the sun is abundant enough, or the volume in the current environment reaches 35-40 decibels, it can dance.

Clause.

Fourth, the longevity flower chameleon

The longevity flower chameleon is a very popular variety, because this variety of longevity flowers have many flower colors, a pot of chameleon has pink, yellow, white, etc., which is also determined by sunlight, temperature and the length of flowering time.

Clause.

5. Flowers on leaves

In people's cognition, the leaves of flowers are leaves, flowers are flowers, flowers open branches or leaf axils, or pull out alone, but the flowers on the leaves are more magical, its flowers are on the leaves, flowers on the leaves, fruits on the leaves, very magical.

Magical color-changing flowers.

We generally think that water flows to the lower part of the ridge, but water can also flow to the high part of the rock infiltration! Do an experiment to change the color of the flowers, and you will see how the plants get the water they need to grow.

Here are the steps of my experiment:

1.Add a different coloring to each glass of water.

2.Carefully cut the stem of a flower under the flower head. Trim the stems and roots of each flower.

3.Place the split flower stems into two different cups. Place the sprig with the complete stem in the third cup.

4.Put the flowers in a warm room. After an hour, they begin to change color, they absorb the colored water and move up the flower stem to the petals of the jujube nada.

5.The celery is removed from the roots and placed in red-colored water, which rises along the stem to the leaves, and the celery leaves turn red. If you cut a section of celery, you can see the veins of the celery rising with water.

After this experiment, I learned that flowers can also change color.

Flowers that can be raised in water at home Plants that can be hydroponic at home are; Pothos, spider plant, narcissus, hyacinth, rich bamboo, water lily, lotus. Precautions for raising flowers in water: 1. Suitable ambient temperature:

The growth temperature of hydroponic plants is 5 -30 , and they can grow normally in this range. 2. Appropriate light: The light of hydroponic plants is mainly scattered light, and it does not necessarily have to be exposed to the sun.

In summer, direct sunlight should be avoided as much as possible. 3. Change the water and clean the roots of the flowers: Change the water for hydroponic plants about 7 days in summer and change the water about 10-15 days in winter, and add a few drops of hydroponic flowers or special nutrient solution for burning flowers (the concentration of the nutrient solution is prepared according to the requirements of the manual).

Vessels used to grow hydroponic plants are prone to moss, which affects the ornamentation of the root system and consumes oxygen in the water. When changing the water, you should first wash off the mucus of the flower roots with clean water, and cut off the old roots and rotten roots. And wash the utensils and roots with moss.

Each time the water is changed, the interface of the water should be submerged in 1 2-2 3 of the root system, and the rest of the root shed is left to be exposed to the air. 4. Moisturizing and spraying foliar fertilizer: In order to prevent the occurrence of leaf drying, during daily clothing deficiency care, foliar moisturizing should be sprayed with water, and it is best to spray foliar fertilizer once a week, which can not only provide nutrients for the leaves, increase the luster of the leaves, but also achieve the purpose of resisting low temperature in winter.

1. The magic principle of flowers in water: "high capillary or stuffy phenomenon", because paper is composed of many plant fibers, the gap between the fibers is extremely small, and countless small capillaries are formed. After the paper and water come into contact, the water will quickly infiltrate into the bending gap of the paper, and the tension and shape of the paper will be changed, so the phenomenon of flowers blooming in the water is formed.

2. The capillary is inserted into the infiltrated liquid, and the liquid level in the tube rises and is higher than the outside of the tube, and the capillary is inserted into the non-infiltrated liquid, and the liquid in the tube drops and is lower than the outside of the tube, which is called capillary phenomenon.
