System of summer assignments in biology

(from work experience).

The city of Essentuki is located in the specially protected ecological resort region of the Caucasian Mineral Waters. This imposes certain restrictions on collecting wild plants and visiting certain areas where plants and animals live. But during the summer holidays, schoolchildren travel to different areas of the Stavropol Territory, regions of Russia and abroad, and it becomes possible to create the necessary educational and visual aids, especially since our school does not have a teaching and experimental site. Currently, we have the opportunity to purchase many manuals in ready-made form, but, firstly, they are quite expensive, and secondly, they do not always meet all the necessary requirements. This is how the system for preparing summer assignments developed. Submission and defense of completed work takes place in the first lessons at the beginning of the school year, which gives students the opportunity to get good grades as soon as they start studying. Some summer assignments are completed in the form of projects by students who attend the school’s summer environmental camp. It should be noted that not all students take their summer assignments seriously; some even forget about them. But most of the children, as a rule, are conscientious about completing the summer assignment, and for many years we have been using these works in the classroom as demonstration material and aids for laboratory and practical work. An exhibition is usually organized of the best works, which arouses great interest among all students and stimulates further work.

When organizing summer assignments, we set certain goals and objectives:

· acquaintance with the flora and fauna of the native land;

· development of skills in collecting and herbarizing plants;

· development of skills in the production of various educational and visual aids necessary for replenishing the school biology classroom;

· practical application of knowledge acquired during the academic year;

· conducting observations of the life of plants and animals, confirming the facts and patterns studied in lessons.

With the successful completion of these tasks, interest in the educational subject arises and develops, which contributes to the conscious and lasting assimilation of the fundamentals of biology.

Summer assignments can be completed individually or in a group setting. They are adjusted according to the degree of difficulty, taking into account the student’s individuality, his abilities and capabilities, and voluntariness. The teacher needs to help the student choose the right topic for the assignment, give appropriate instructions, and show the best work completed in previous years. Summer assignments can be classified according to the age of the children, by topic, and by the location of the students in the summer. Some tasks are distributed throughout the school year, since the observed processes occur in the autumn, winter or spring. Assignments are accepted, depending on the content, in the form of properly designed herbariums, collections, photographs, electronic presentations, etc. The rules for being in nature, collecting material, the need to study protected species, excluding their accidental destruction, as well as the impossibility of causing harm must be stipulated or pain to any living object.

It is difficult to list in one article all the possible summer assignments that are assigned to students. But in September it turns out that the guys even found what was not assigned. These are photographs of insects while collecting nectar, fossil shells in a coastal section of a river, a photograph of a dry river that a child can step over in summer, or an aerial view of his native land from the height of a cable car, seafood brought from the Black Sea coast, crafts made from natural materials with your own hands.

We gladly and gratefully accept all the material that the guys collect, we help identify and systematize it.

Of course, organizing and checking summer assignments requires a lot of work, time, and patience from the teacher, especially since it occurs at such a busy time as the end and beginning of the year. But the result, the benefits of which are undoubted, is worth the time and effort.

Among our graduates there are those who decided on their choice of profession thanks to completing summer assignments.

Summer assignments in biology for students who have completed 5th grade.

The purpose of this work: accumulate information necessary for subsequent study

sections of the school biology course in 6th grade.

Task: give students a program of independent work for the summer in nature.

To document their observations and carry out work, students start a “Summer Observation Diary” - this can be any notebook, notepad, convenient for the children. It is necessary to sign it, indicating the student’s last name, first name, and the date the diary was created. A sheet of printed assignments is pasted into this notebook. Students record their observations in any order convenient for them, but indicate the assignment number. It is possible (and desirable) to accompany your observations with photographs, drawings, schematic sketches, etc.

Task 1. Study of the structural features of algae.

While at sea, pay attention to multicellular algae. Observe the body shape of the algae in the water, and then remove the algae from the water. Pay attention to the shape, has it remained the same or has it changed? Record your observations in a summer observation journal.

Task 2. Stump.

Look at the stump of a recently cut down tree and sketch it. Label the bark and wood in the drawing. Count and write down the number of rings on the wood, indicate on which side (south or north) the rings are wider.

Task 3. Herbarium of simple and complex leaves.

Collect leaves from various plants. Dry them by carefully placing them between newspaper sheets under a press. Then glue or sew them to the cardboard, label simple and complex leaves.

Task 4. Plant root systems.

Consider the root systems of various plants. Identify taproot and fibrous root systems. Find the main root - more developed than the others, and the lateral ones extending from it. Draw, label the drawings, sign the names of the roots.

Task 5. Collection of dry fruits.

Collect a collection of dried fruits from various plants (for example, oak, hazel, sunflower, maple, corn, dandelion, shepherd's purse, radish, etc.). Label the names of the fruits and the type of plant.

Task 6. Study of methods of distribution of fruits and seeds.

Consider the fruits of string, burdock, poplar, maple, dandelion and others. Determine the methods of seed dispersal in these plants, what adaptations the fruits of these plants have for this method of dispersal. Write down your observations in a diary.

Task 7*. Photoherbarium of fungi. When you encounter mushrooms of various types, photograph them or sketch them in your observation diary. Write down the names of the mushrooms, write down in what area they were found, whether they are edible or poisonous.

Task 8*. Collection of inflorescences.

Collect inflorescences of various plants (herbaceous, shrub or woody). Dry them between sheets of newspaper, placing a weight on top (under a press). Draw up the herbarium on thick A4 sheets of paper or cardboard, make signatures - names of plants, date of collection of the herbarium (i.e. time of flowering of the plant).

Task 9*. Making a visual aid: “Tap and fibrous root systems.”

Dig up the root system of a dandelion (or any other flowering plant), or any cereal plant. Rinse it from soil, dry it, attach it to thick paper or A4 cardboard (can be sewn in several places with thick thread). Label the type of root system.

Task 10*. Create a photo herbarium of trees and shrubs in urban landscaping, school grounds, cottages, forest plantations or parks.

Task 11*. Birch, oak, linden. On a sheet of thick paper measuring 20 X 30 cm, draw the outlines of trees on the left side, attach a twig with leaves on the right side, and under the drawing - a piece of bark, as well as a fruit and a flower.

* - students complete tasks with an asterisk to the best of their ability; students can be offered to complete one of these tasks at their choice.

Biology belongs to the natural sciences. The main methods of learning the laws of life are observation and experiment. Mastering these methods has not only scientific, educational, but also developmental and educational significance.

K.A. Timiryazev wrote: “... people who have learned... observations and experiments acquire the ability to pose questions themselves and receive factual answers to them, finding themselves at a higher mental and moral level in comparison with those who have not undergone such schooling.”

In teaching biology, various forms of experimental and research work have been developed for students. This is a demonstration experiment, laboratory and practical work of a desk nature, excursions, phenological observations, field practices, expeditions and summer assignments. Each form plays its role in the educational process, differing in the degree of individualization and complexity of organization, the scale of the work performed and the breadth of student involvement in active activities.

At our gymnasium, we offer summer creative assignments to students. Since 1995, as part of the long-term creative general gymnasium project “Summer Gymnasium”, they have been part of the system of extracurricular project and excursion-research activities of students and teachers of the gymnasium in biology, geography, ecology, history, physics, chemistry, computer science, mathematics, foreign languages, together with teachers and students of higher educational institutions in the cities of Shuya and Ivanovo.

Summer assignments are carried out during the most favorable period of the year, when all vital processes are intense and noticeable changes occur in wildlife. In summer, people's closeness to nature and the activity of communication with it are greatest.

The system of summer creative assignments we have developed for students in grades 5–10 includes preparatory, working and reporting stages. The topics of work cover the entire course of school biology.

Tasks of different levels are offered. Children can choose a task in accordance with their interests and capabilities. When completing the task, students receive methodological assistance:

– instruction cards have been compiled for different types of tasks;
– a selection of bioecological research methods has been accumulated,
– individual and group consultations are organized during the academic year and during the holidays.

The research activities of high school students in the summer are mainly related to environmental monitoring of the environment in their areas of residence. Thus, they become participants in the collective research project “We and Our City.”

Similar work in the microdistrict of our gymnasium is aimed at drawing up an environmental passport of the unique territory of the center of Shuya in order to assign it the status of a natural monument in the future. This is a multi-year environmental project, including field research, chemical analysis, and biological indication. The work is supervised by teachers of biology, geography, chemistry, the scientific supervisors of the project are teachers of the natural geography faculty of Shuya State Pedagogical University (SHPU).

Natural science excursions are conducted in three main areas: medical, agricultural and environmental.

Summer assignments for 10th grade natural science students are closely intertwined with their activities during creative practice at the Yasen summer specialized camp. For graduates of the physics and mathematics class, it is interesting to develop topics on bionics, the technical implementation of the perfect principles of the structure and functioning of living systems:

– biomechanical models,
– live weather stations,
– biocommunication, dowsing and navigation,
– beauty and expediency in architecture, etc.

We consider the success of our students to be the most important result of our work. They become prize-winners and winners of city and regional Olympiads in biology and ecology; prize-winners of city competitions of student research works in the field of ecology and diploma winners of regional environmental conferences.

Graduates of the 9th and 11th grades annually defend research abstracts at the final certification. Our students present their research works and collective projects at the scientific conference of students of the Faculty of Natural Geography of ShSPU.

Study of the structure, behavior and soil-forming activity of earthworms

Family of true earthworms, or Lumbricidae, ( Lumbricidae) includes about 300 species. The most common species in the central zone of the European part of Russia is the common earthworm, or large red crawler, ( Lumbricus terrestris), characterized by its large size, flattened and widened caudal end and intense coloration of the dorsal side of the anterior third of the body. This view is convenient for observations and experiments.

1. Catch several specimens of the common earthworm, place one of them on a flat surface and study its external structure.

– What is the body shape of an earthworm?
– Why is the earthworm called ringed?
– Find the anterior (thickened and darker) and posterior ends of the worm’s body, describe their color.
– Find a thickening on the worm’s body – a belt. Count how many body segments form it.

Turn the worm with its ventral side up and run a finger moistened with water along the ventral side from the rear end of the body to the head. How do you feel? Let the worm crawl on the paper. What do you hear?

Using a magnifying glass, find the bristles and describe their location and meaning.

Determine how fast the worm moves on glass and on rough paper, and how the shape, length and thickness of the body changes. Explain the observed phenomena.

2. Observe how the worm reacts to stimuli. Touch it with the needle. Bring a piece of onion to the front end of the body without touching the worm. Light it with a flashlight. What are you observing? Explain what is happening.

3. Make a narrow-walled cage from two identical glasses (12x18 cm) and a spacer between them (rubber tube, wooden blocks). Fasten the glass together using brackets cut from thin tin. You can also use two glass jars (half-liter and mayonnaise), placing the smaller one in the larger one.

4. Pour a small (about 4 cm) layer of moist humus soil into the cage, then a layer of sand and humus again. Place 2-3 small earthworms on the surface of the cage. Watch as the worms burrow into the top layer of soil. Try to grab the half-buried worm by the end of its body to pull it back out. Is it easy to do? Why?

5. Describe, sketch, or photograph changes in soil conditions in the cage every 3–5 days. Examine the inner surface of the earthworm tunnels. What is the importance of mucus for the life of a worm in the soil?

6. Place 3-4 worms in a glass jar and fill half of the jar with clean sand. Keep the sand moist, place fallen leaves, tops of various plants, and pieces of boiled potatoes on the surface of the sand. Keep track of what happens to them. After a month, measure the thickness of the formed humus, draw a conclusion about the influence of earthworms on the composition and structure of the soil, its fertility.

7. Write a detailed report on the experiments and your observations, accompanying the description with drawings and photographs. Evaluate the significance of the activities of earthworms in nature and for humans.

Study of trait variability in a population

1. During the summer period, collect material on intraspecific variability of a trait (in 25–50 individuals of the same species, breed, variety).

2. These may be signs such as:

– growth of children (boys and girls separately);
– size of beetles (May beetles, Colorado beetles, etc.);
– daily milk yield of a group of cows of the same breed;
– size of ears of wheat, rye;
– size of flowers of tomatoes (cucumbers, strawberries, etc.) of one variety;
– size of fruits, seeds, number of seeds in a fruit of peas, beans, beans of the same variety;
– the size of tubers of potato plants of the same variety that do not belong to the same bosom;
– the size of acorns collected in an oak grove;
– size of chickens of the same age of the same breed;
– size of eggs of chickens of the same breed, etc.

3. Process the collected material:

– compile a variation series of the severity of the trait under study in the population and indicate the frequency of occurrence of each variant;
– determine the average value of this trait in the population;
– construct a graph of the relationship between the value of the trait and the frequency of its occurrence in the population.

4. Establish the pattern of variability of this trait in the population.

5. Prepare your work on an A4 sheet.

6. Use the results obtained when studying the question “Forms of natural selection in populations.”

7. Think:

– what is the difference between the concepts of “population gene pool” and “organism genotype”;
– what is the difference between the formation of the average value of a trait of an organism and the average value of a trait of a population;
– what is the biological significance of the variability of an organism’s trait and the variability of a trait in a population of organisms.

By studying botany and zoology, you learned a lot about plants and animals, their diversity, significance in nature and human life. But you received all this knowledge mainly in classes, as well as from books, movies and television shows. However, there were few direct observations in nature. In the summer you can compensate for this lack of study of plants and animals. Summer is the period of their active life. Enter this wonderful world of plants and animals! Observe its life and diversity of forms, study organisms in their natural environment! But be sure to remember: plants and animals are kingdoms of living beings, and they must be treated with care, taking care of the well-being of each plant and animal and nature as a whole.

What should we study in nature? Choose any topic that interests you about any plants (ornamental, wild, indoor; about one plant or a group of plants) or any animals (domestic or wild, large or small: animals, birds, insects, arachnids, mollusks, worms, etc.) . Observe your chosen plant or animal! Next, formalize your observations in the form of a research paper, abstract, or computer presentation. It is recommended to use your own photographs of plants and animals. You can use recommendations for summer assignments from textbooks. Instead of observations, you can do any creative work whose theme is related to nature, plants or animals. The works are due in September.
By making observations in nature, you will see how much interesting there is in nature near you. And you don’t have to go anywhere far to do this!


Good luck!

Instruction cards for summer assignments

1. Study of plant adaptations to cross-pollination

1. Identify the pollination modes of different plant species using simple visual observations.

2. Place slides smeared with Vaseline near the flower. Examine the pollen of the plant species under study under a microscope, describe and sketch it.

3. Carefully examine the structure of flowers of different plants. Find out how they are adapted to a particular type of pollination. Describe and sketch the flowers and the adaptations they have.

4. Observe the “behavior” of flowers. Find out the time of their opening, describe and sketch the sequence of bending, unwinding of the petals, stretching of the stamens, changing the position of the flower, etc. Determine the lifespan of a flower.

5. Observe the “behavior” of the inflorescences and the arrangement of flowers in them. Find out whether the flowers in the inflorescence are the same and whether they open at the same time.

6. Observe the behavior of insects on the plants under study: what insects visit the flowers, how the insect lands on the flower, how long it stays on it. Observe the movements of the insect's legs and mouthparts. Count the frequency of insects visiting a flower in one hour at different times of the day.

7. You can follow the characteristics of pollination of one type of plant in different conditions (in a forest, in a meadow, at the edge of the forest...).

Study of the structure, behavior and soil-forming activity of earthworms.

2. Study of the structure, behavior and soil-forming activity of earthworms

Family of true earthworms, or Lumbricidae, ( Lumbricidae) includes about 300 species. The most common species in the central zone of the European part of Russia is the common earthworm, or large red crawler, ( Lumbricus terrestris), characterized by its large size, flattened and widened caudal end and intense coloration of the dorsal side of the anterior third of the body. This view is convenient for observations and experiments.

1. Catch several specimens of the common earthworm, place one of them on a flat surface and study its external structure.

What is the body shape of an earthworm?
- Why is the earthworm called ringed?
- Find the anterior (thickened and darker) and posterior ends of the worm’s body, describe their color.
- Find a thickening on the body of the worm - a belt. Count how many body segments form it.

Turn the worm with its ventral side up and run a finger moistened with water along the ventral side from the rear end of the body to the head. How do you feel? Let the worm crawl on the paper. What do you hear?

Using a magnifying glass, find the bristles and describe their location and meaning.

Determine how fast the worm moves on glass and on rough paper, and how the shape, length and thickness of the body changes. Explain the observed phenomena.

2. Observe how the worm reacts to stimuli. Touch it with the needle. Bring a piece of onion to the front end of the body without touching the worm. Light it with a flashlight. What are you observing? Explain what is happening.

3. Make a narrow-walled cage from two identical glasses (12x18 cm) and a spacer between them (rubber tube, wooden blocks). Fasten the glass together using brackets cut from thin tin. You can also use two glass jars (half-liter and mayonnaise), placing the smaller one in the larger one.

4. Pour a small (about 4 cm) layer of moist humus soil into the cage, then a layer of sand and humus again. Place 2-3 small earthworms on the surface of the cage. Watch as the worms burrow into the top layer of soil. Try to grab the half-buried worm by the end of its body to pull it back out. Is it easy to do? Why?

5. Describe, sketch or photograph in detail changes in the condition of the soil in the cage every 3-5 days. Examine the inner surface of the earthworm tunnels. What is the importance of mucus for the life of a worm in the soil?

6. Place 3-4 worms in a glass jar and fill half of the jar with clean sand. Keep the sand moist, place fallen leaves, tops of various plants, and pieces of boiled potatoes on the surface of the sand. Keep track of what happens to them. After a month, measure the thickness of the formed humus, draw a conclusion about the influence of earthworms on the composition and structure of the soil, its fertility.

7. Write a detailed report on the experiments and your observations, accompanying the description with drawings and photographs. Evaluate the significance of the activities of earthworms in nature and for humans.

3. Pet monitoring

Find out what trees and shrubs grow near your home, how plants of each of these life forms differ from each other, which of them grow well and which are in a depressed state, what period of life (flowering, fruiting, etc.) they go through in the summer, which of them are the most decorative.

Collect one leaf (or a shoot with two or three leaves) from each type of tree and shrub, straighten and dry them between sheets of newsprint, and then attach them to sheets of thick white paper and write the names of the plants to which they belong.

8. Study of the species composition of herbaceous plants growing in urban or other settlements. Determine what species (or genera) the grasses growing near your home belong to, what adaptations they have developed to survive in conditions of trampling and other human influences, which of them predominate in numbers and which are quite rare, in what state (flowering , fruiting) they are in the summer.

Compare them with each other and find out how they differ in the shape of shoots, leaves, structure of flowers or fruits.

Dig up one plant of each type, rinse them in water, dry them a little in the fresh air, straighten them and dry them between sheets of newsprint, and then make herbarium sheets with signatures of the names of the plants placed on them.

9. Determining the influence of living conditions on the appearance of trees. Select for observation trees of the same species and approximately the same age, growing in the open, at the edge of the forest and in its depths. Find out how they differ in the arrangement of branches on their trunks, the shape of their crowns, and the height and thickness of the trunks.

Decide what growing conditions affect the appearance of the trees. Make a schematic drawing of the observed trees with labels of their places of growth.

10. Study of the species composition of plants growing in wastelands. Select some unused area between buildings, along fences, or in other areas called vacant lots. Find out which of the plants - burdock, thistle, thistle, nettle, wormwood, datura, henbane - grow in the selected area, what signs are characteristic of this group of herbaceous plants and why people and animals usually bypass the places where they grow, which of them have thorns, stinging hairs or other adaptations to protect themselves from being eaten by animals, which of them are Asteraceae and which are Solanaceae.

Collect and dry the side shoots of waste plants and then make herbarium sheets with the names of the plant group and its representatives.

11. Study of the composition of the roadside plant community. Select any section of a pedestrian road and determine which of the plants - plantains, dandelion, creeping clover, odorous chamomile, goose's foot, knotweed (bird buckwheat, ant herb), goose's foot - grow on its sides.

Find out which of the roadside plants have a shortened stem, and which ones have a creeping or low-rising stem, which plants have leaves with highly developed elastic veins, and which ones have small or heavily dissected ones. Decide what significance such structural features have in the life of roadside plants.

Determine in what state (flowering or fruiting) certain roadside plants are in the summer, which of them predominate in numbers, and which are quite rare.

Collect material for mounting herbarium sheets based on the species composition of plants in the roadside community.

12. Observations on the state of plants with barometers. Observe the condition of the flowers of yellow acacia, mallow, field bindweed, wood lice and dandelion inflorescences, marigolds (calendula). Find out what happens to their flowers or inflorescences in inclement weather before the onset of rain. Think about why they developed such devices.

Find out which other plants and how they can predict the approach of rain. Collect one barometer plant at a time, dry them between leaves of newsprint and mount herbarium sheets with captions of the names of the plants.

13. Observations of plants using a flower clock. Observe the opening and closing times of flowers or inflorescences of some wild and garden flowering plants, for example, dandelion, marigolds, morning glory. Find out at what time the flowers of some other flowering plants that are most familiar to you open and close.

Establish what causes the observed phenomena in plant life. For drying and making herbarium sheets, collect several plants that open flowers or inflorescences at a strictly defined time of day.

14. Study of weed adaptations to living conditions. Find weeds in the fields of cultivated cereal plants that are similar in external structure to them: in rye, wheat and barley, oats - rye brome, field brome, wild oats; for millet - barnyard, chicken millet.

Determine how the named weeds are similar to cultivated cereals. Decide what significance it has for weeds to resemble the cultivated plants they accompany.

Collect and prepare a herbarium of cultivated cereal plants and accompanying weeds.

15. Study of ways plants distribute fruits and seeds. Determine the time of formation of fruits and seeds in some plants, for example, sow thistle, thistle, string, burdock, impatience, dandelion. Collect their fruits and seeds and determine which of them have developed adaptations for dispersal by wind or animals, self-dispersal, and how this or that adaptation is manifested.

Make a collection of fruits and seeds distributed by plants by wind, animals and self-dispersal.

16. Study of the composition of plants in a mixed forest. Find out which trees are most common in a mixed forest, which of them form the first (upper) and which - the second tiers, how the trees that form the first and second tiers differ from each other. What plants form the third and fourth tiers of a mixed forest? How do the living conditions of plants in these tiers differ from the living conditions of plants of the first and second tiers?

Collect one herbaceous plant from a mixed forest, dry them and prepare herbarium sheets with the names of the objects included in them.

17. Plan for completing a summer assignment in invertebrate zoology.

1. Find literature about your chosen natural object (insect).

2. Read the literature carefully, note interesting facts in your observation diary

3. In the study diary (it can be in electronic form), note:

a) Describe your lifestyle.

b) The external structure of the animal, and adaptations for life in a given environment

c) Nutrition (what does it eat, feeding habits, adaptations)

d) Animal movement

4. Take a photograph of the animal (its appearance, while feeding, while moving).

  • It is no less difficult to make a good photo collection of insects, especially if you set yourself the task of determining the species, studying the lifestyle, etc.
  • But in general, it's quite interesting to just photograph insects and other animals. And then just on occasion, find out something about them...

18. Plan for completing a summer assignment in vertebrate zoology.


1. What birds come to us in the summer? (Find the species name from the literature). Take photos and record them in your observation journal.
2. Remember (or ask your family and friends) signs, weather harbingers associated with animal behavior, write them down in a diary and, if possible, observe the animals. Are the forecasts true? (write down the date and result).

The work is considered to be excellent if natural material (photos) and a recording of observations are presented.

    THANK YOU so much for the very useful information in the article. Everything is presented very clearly. It feels like a lot of work has been done to analyze the operation of the eBay store

    • Thank you and other regular readers of my blog. Without you, I would not be motivated enough to dedicate much time to maintaining this site. My brain is structured this way: I like to dig deep, systematize scattered data, try things that no one has done before or looked at from this angle. It’s a pity that our compatriots have no time for shopping on eBay because of the crisis in Russia. They buy from Aliexpress from China, since goods there are much cheaper (often at the expense of quality). But online auctions eBay, Amazon, ETSY will easily give the Chinese a head start in the range of branded items, vintage items, handmade items and various ethnic goods.

      • Next

        What is valuable in your articles is your personal attitude and analysis of the topic. Don't give up this blog, I come here often. There should be a lot of us like that. Email me I recently received an email with an offer that they would teach me how to trade on Amazon and eBay.

  • It’s also nice that eBay’s attempts to Russify the interface for users from Russia and the CIS countries have begun to bear fruit. After all, the overwhelming majority of citizens of the countries of the former USSR do not have strong knowledge of foreign languages. No more than 5% of the population speak English. There are more among young people. Therefore, at least the interface is in Russian - this is a big help for online shopping on this trading platform. eBay did not follow the path of its Chinese counterpart Aliexpress, where a machine (very clumsy and incomprehensible, sometimes causing laughter) translation of product descriptions is performed. I hope that at a more advanced stage of development of artificial intelligence, high-quality machine translation from any language to any in a matter of seconds will become a reality. So far we have this (the profile of one of the sellers on eBay with a Russian interface, but an English description):
