Project “Development of plants from seeds” Completed by: Arina Solodkaya, 3b grade student MBOU Secondary School No. 4 Head: Fedotova N.A. 2015 Goal: theoretical and practical acquaintance with the structure and development of seeds of flowering plants Relevance: studying this topic in a lesson about the world around us

• Tasks:
• learn the history of the appearance of beans in our country
• find out the importance of legumes in human life, what is needed to grow beans
• observe and study the growth of plants from seeds
Problem:
• what is necessary for the growth of beans and peas
• Hypothesis:
• we assume that if beans are planted in the classroom, they will not grow, as they grow in the field or in the garden.

Stages of work.

Project - research, natural science, personal

Methods: observation, analysis, working with the Internet, with the textbook “The World Around us”

1.Preparatory stage:

Gathering information on the project topic, reading additional literature and

reference material

2. Conducting research and summarizing the results

observations of the growth of bean and pea seeds, comparative analysis, conclusions

3. Preparing for the presentation:

Summarizing your observations, conclusions, preparing visualizations

4. Presentation

The homeland of beans is the Mediterranean countries, from there they spread throughout Europe, Asia and Africa.

The history of the appearance of beans in our country.

Beans came to Russia from Greece. They were often bred in Russian villages. Usually they were planted along the edges of beds with carrots and onions as curtains for protection from the wind. But beans have not become widespread as a field crop in Russia. Only small-seeded varieties are sown, the seeds of which are used as feed, and straw is added when ensiling corn. Nevertheless, in 1999 Russia was in the top ten world exporters of grain beans.

Russian or fava beans. Legume family.

Beans are an annual bluish-green herbaceous plant from the legume family. They have a well-developed root system. The stem is erect, up to 2 m high. The fruits are large beans, brown or black in color when ripe.

L medicinal value of beans:

In folk medicine, a decoction of bean seeds is used for diarrhea as an astringent and anti-inflammatory agent.

For external use, it is better to boil the seeds not in water, but in milk. Seeds boiled with milk are applied to abscesses. Heated seed flour is applied to boils, abscesses and inflamed areas of the skin. A poultice made from seed dough cures malignant ulcers and cleanses the skin.

Beans are indicated for diabetes.

I took out the seeds from the bean pods.

I saw that the bean was different in size, the same dark purple color, smooth, and had a depression at the top.

The seeds were dry. I put them in the lid of the jar. I saw that the bean was different in size, the same dark purple color, smooth, and had a depression at the top.

The seeds were dry. I put them in cups and poured water.

1. The embryo is a seed, a carrier of heredity.

3. Seed coat – protection for long-term storage.

4. Cotyledons – storage of nutrients.

Seed structure

What does a seed consist of?

The peas grew faster. The sprout is 8 cm, and the bean has just entered.

Peas are growing on the window. It already has flowers, many tendrils that cling to sticks, but the leaves begin to turn yellow and lack nutrition.

The bean grows on the window and is 53 centimeters long. It already has flowers, but the stem is thin and falls without a stick.

During the summer I attended a school camp and continued to watch my beans and peas. We have achieved an interesting result. Our bean has bloomed and produced fruit. The peas even managed to dry out and now the harvest is 1 pod with a pea

For seed germination you need: heat, light, water, soil, fertilizers.

The first root to emerge from the seed grows downward.

Then a stem appears on which leaves develop.

If the soil is fertile, the plant grows better and faster.

A weak plant grew in the sandy soil and soon withered.

Beans need to be watered and fertilized regularly.

We disproved the hypothesis that beans cannot be grown indoors. Can. You just need to take good care of it.

Literature:

Thank you for your attention.

See you again!

Presentation provides information to a wide range of people in a variety of ways and methods. The purpose of each work is the transfer and assimilation of the information proposed in it. And for this today they use various methods: from a blackboard with chalk to an expensive projector with a panel.

The presentation can be a set of pictures (photos) framed with explanatory text, built-in computer animation, audio and video files and other interactive elements.

On our website you will find a huge number of presentations on any topic that interests you. If you have any difficulties, use the site search.

On the site you can download free presentations on astronomy, get to know the representatives of flora and fauna on our planet in presentations on biology and geography. During school lessons, children will be interested in learning about the history of their country through history presentations.

In music lessons, the teacher can use interactive music presentations in which you can hear the sounds of various musical instruments. You can also download presentations on MHC and presentations on social studies. Lovers of Russian literature are not deprived of attention either; I present to you my PowerPoint works on the Russian language.

There are special sections for techies: and presentations on mathematics. And athletes can get acquainted with presentations about sports. For those who like to create their own work, there is a section where anyone can download the basis for their practical work.

This development contains a lesson summary and presentation.

"Group Study"

Group Study No. 1

Purpose of the study:

Sprout a bean seed and grow a mature plant to learn how the plant develops.

Research and prove that plants need water to grow and develop.

Instructions:

Place a cotton pad at the bottom of each glass.

Place bean seeds in two glasses.

In the first glass, leave the seeds dry, without water.

Pour some water into the bottom of the second glass.

Place both glasses in a warm, lit place.

Group Study No. 2

Purpose of the study:

2) Research and prove that plants need air to grow and develop.

Instructions:

3) Fill the first glass to the brim with water.

4) Pour some water into the bottom of the second glass.
