Contribution to science

Belgian explorer of nature Jan Van Helmont

Having carried out the first physiological experiment, we connected the plants with food.

English chemist Joseph Presley

Having proven the truth: having placed the mouse under the cursed cowpak, and within five years the creature died. When the meat was introduced under the hood, Misha lost her life. In the future, it is important that the green plants of the building create protracted reactions to the dichotomy processes.

Dutch doctor Jan Ingenhaus

During the experiment, it was revealed that the plant species see sourness only in the presence of monsoon light, and that their green parts are responsible for the visible sourness.

Swiss opinion Jean Seneb'ie

It has been experimentally proven that organic speech in plants is dissolved by carbon dioxide, which is decomposed in the green organoids of plants under the influx of sunny light.

French physiologist Roslin Jacques Boussingault

In the course of laboratory work, it was discovered that water is also combined with plants during the synthesis of organic substances.

German botanist Julius Sachs

Having proven that the ratio between carbon dioxide, which is being burnt, and sourness, which appears to be 1:1. demonstrating the transformation of grains into starch during photosynthesis

Piznavalnye Zavodnya:

· Root mass of a small tree 5 kg. One kg of root mass is equivalent to 1 g of sauerkraut. What kind of kisnu does the root of a tree sustain in a month and a week? (: for 30 days - 150 g; for 365 days - 1825 g)

· What kind of growth trims in the vine more than a saw on the surface of the leaf: elm or poplar? Why? (The elm has a short leaf, it has 6 times more irritation than the smooth surface of the poplar leaf)

· What is the relationship between the collection of leafy vegetables (crisps, spinach, lettuce, etc.) and the time of preparation? Why? (In the evening, at this hour the maximum of organic substances accumulated during the process of photosynthesis during the day, and at night these substances flow to other organs.)

· The lady at the dacha was picking green cabbage leaves to feed the rabbits. Did she do it right? Why? (No, incorrect. Organic compounds created in the green leaf during photosynthesis flow out from the white leaf of the plant and accumulate there)

· For the spoils, a person can buy 430 g of kisnu. One hectare of forest produces as much sour in a year as is needed to feed two hundred people. How can a masa see a hectare of forest in a year? (Video: 3580 g)

· During the process of photosynthesis, the fruits that grow in greenhouses are processed by 1 kg of carbon dioxide when 7 kg of fruits are processed. How many kg of carbon dioxide will be required to produce 300 kg of ogirki? How can you increase the amount of carbon dioxide in the greenhouse? (Video: 42.85 kg; added to the soil with pus, peat enriches the surface with carbon dioxide, which is visible from the soil when organic matter is laid out by microorganisms)

· K.A. Timiryazev wrote: “In essence, so as not to destroy the rural ruler, it is the chlorophyll that first vibrates, and after that chlorophyll, grain, fiber, wood, etc. are removed.” What agrotechnical practices prevent the accumulation of chlorophyll and increased photosynthesis in leaf pulp? (Example: adding organic fertilizers to the soil, adjusting the rules for planting sprouts, garnishing lightening, adjusting the rules for watering sprouts)

I. Organizational moment.

1) What process is the quotation talking about? “.When the sun fell to the Earth, it didn’t fall on barren soil, but it fell on a green sprout, or, to put it more simply, on a chlorophyll grain. Varying about him, he faded away, ceasing to be light, and no longer knew. You’ve lost too much money on internal work...” (K.A. Timiryazev)

2) Working with cards individually (addendum 1).

III. Vivchenya new ones

Carbon dioxide + water + solar energy =

Organic speech (tsukor and starch) + kisen

Well, the life of the Earth lies beneath the sun. And the accumulated energy is the greenery of the plants. Photosynthesis is a unique process - even on earth there is always the creation of organic substances from inorganic ones, simply from carbon dioxide. Organic speeches then vikorist with other creatures and people. In this way, the energy of the sun, stored in green plants in peels, fats and proteins, will ensure the life of every living thing on Earth - from bacteria to humans.

A prominent Russian scholar, Kliment Arkadiyovich Timiryazev, studied this process and named the role of green shoots on Earth as cosmic.

At the hour of our work, we understand why the role of roses is called cosmic.

1. The cosmic role of roses.

Last lesson we talked about the most important process on Earth - photosynthesis. Let's repeat the formula for the process one more time. Sign up for additional formulas.

Well, the life of the Earth lies beneath the sun. And the accumulated energy is the greenery of the plants. Photosynthesis is a unique process - every day on earth there is the creation of organic substances from inorganic ones, simply from carbon dioxide. Organic speeches then vikorize between creatures and people. In this way, the energy of the sun, stored in green plants in peels, fats and proteins, will ensure the life of every living thing on Earth - from bacteria to humans.

A prominent Russian scholar, Kliment Arkadiyovich Timiryazev, studied this process and named the role of green shoots on Earth as cosmic.

At the end of our work, it becomes clear why the role of roses is called cosmic.

Work in groups with cards.

After working in groups using cards per school, one student from the group writes down the most important learnings. Learn to write down sewing patterns.

The icons appear approximately like this:

Roslins create organic speech from the food of other organisms.

The energy of the sun is accumulated in plants and transferred to other organisms.

Carbon dioxide, which is seen by animals, and when rotting and mountainous growths support its stable storage in the atmosphere.

Roslins create jelly for food and the ozone layer, which protects living organisms.

When the weeds and vegetables are laid out, a soil rich in mineral substances is created, which can allow the weeds to sprout again.

Questioning the teacher. What exhibits interconnections between living and nonliving nature?

Now let’s put together a diagram of the interaction of living and inanimate nature.

Visnovok: What is the cosmic role of roses?

Learn to recap: “Green plants and chlorophyll play an extremely important – cosmic – role in the life of our planet. And how to respectfully take care of the growths.

2. People pour in.

There is little information from scientists about the role of humans and their influence on the steel of the gas warehouse of the atmosphere.

1) Contamination of the atmosphere with gases and an increase in carbon dioxide, the “greenhouse effect”.

2) Ozone “holes” become sour in the atmosphere.

3) Virus the forests and burn them by releasing oxygen and carbon dioxide.

4). Change the soil, especially in places where the leaves are collected from aspen.

IV. Consolidation of the researched material.

a) organic speeches; b) inorganic speeches; c) nothing is hidden.

Green plants, absorbing the energy of the sun, transform them into:
a) on the energy of chemical bonds; b) thermal energy; c) don’t recreate it.

The role of green shoots is called cosmic, because:
a) the stench from space takes over the energy of the dormouse light; b) fragments of our planet are in space; c) do not acquire energy from space.

Appearing from the rising of the earth's growths:
a) kisen; b) carbon dioxide; c) nitrogen

The energy of the sun, which came from space, is stored in plants in the form of:
