Man is a part of nature, and by destroying nature, he destroys his future, the future of his descendants. “We are all passengers of the same ship named “Earth”, and there is simply nowhere to transfer from it” Antoine de Sainte-Exupery Rationale for the project
3 slide
Purpose: to study the influence of anthropogenic factors on human health. Tasks: generalization of knowledge about anthropogenic factors; updating knowledge about pollutants that are very dangerous for all living things; study of the level of pollution of the atmosphere and nature by anthropogenic (artificial) sources
4 slide
Research hypothesis. If a person does not learn to process the products of his activity harmful to all living things, then this can lead humanity to a catastrophe and self-destruction.
5 slide
Forms of work: excursions; sociological survey research and calculation work in teams; drawing up tables and diagrams by means of computer technology; messages and presentations of students; subbotniks for cleaning and landscaping the village; publication of leaflets - appeals to the villagers

Stage 2 - sociological survey Do you think our village is clean or polluted?

Stage 3 - research: 1. Identification of the effect of combustion products on atmospheric air. We found out: 1. As a result of burning garbage, a huge amount of carbon dioxide enters the atmosphere, which destroys the ozone layer of the atmosphere. 2. When burning polyethylene waste, toxic substances (benzpyrenes, carbon monoxide, unsaturated hydrocarbons, dioxins) are released, which suppress the immune system, are carcinogens, lead to early aging, cause gene changes, suppress human reproductive function, affect the psyche, etc.

2. Determination of the degree of air dustiness at different times of the year in areas near the school, near the road and in the center of the village. autumn

Degree of snow dustiness Snow samples were taken in different parts of the village: No. 1 - near the school No. 2 - near the road No. 3 - the center of the village The amount of dust per 1 sq.m. per season Snow sampling site mf, g ms,g m,g Amount of dust (g) per 1 sq.m. for season #1 2.6 2.95 0.35 35 #2 2.6 3.23 0.63 63 #3 2.6 3.26 0.66 66

Stage 4 - analysis of research results During the study, it was found out that the air is polluted by the person himself as a result of his careless activities; Clarified the quantitative characteristics of anthropogenic pollutants, found out their impact on human health; Convinced of the global nature of anthropogenic air pollution and the need for urgent action to clean it up; Learned that snow is an indicator of air pollution; We were convinced that mechanical pollution not only spoils the beauty of our village, but is no less dangerous for human health.

Human progress leads to undesirable pollution of nature and air; The atmosphere knows no boundaries, which means that the air in one place can be strongly influenced by actions taken in another, and these actions must be reasonable. Preserving the purity of nature and air for our and future generations is not only the task of all mankind as a whole, but also of each person individually. Everyone should remember this.

Ecology Ecology is a science that studies the interaction of animals and plants.
What are the types of pollution? People pollute water, air, land.
Water pollution On the banks of lakes and rivers, people build factories and factories. Thus, they pollute the water in these reservoirs!
Life on earth is not possible without water! Each person consumes not 1 or 2 liters of water per day, but much more! the earth has the most water.
Air pollution. Without air, as well as without water, life on earth is not possible! But his people also pollute by building factories, factories and just driving a car.
Earth Pollution of the earth is also very dangerous! Earth. Like everything else, it must be protected, protected and protected.
What happened can't be returned! How many beaches have turned into garbage dumps! How many quarries dug and left. But there you could relax and enjoy life!
Animals suffer! Animals suffer from soil, air and water pollution!!!
The situation can still be saved! Stop driving! Get up and walk. Don't be lazy! And it will help everyone!
Protect the environment!!! "Save nature" - everyone can say! But not everyone can do it.
What is your world like? GREENPEACE is engaged in the protection of nature. But what nature will be like in the future depends on everyone. Including from you!

Ecology is one of the most important disciplines. On it, students learn how to protect and preserve the environment. Unfortunately, it is problematic to learn it qualitatively only from textbooks, and in this case, presentations on ecology will be an excellent way out of the situation. It is much easier and easier to visually show something than to explain it in words for a long time. Each presentation contains a large number of slides, audio and video, so classes on ecology will be truly interesting and informative for students.
Presentations on ecology are made in the PowerPoint program, here you will find a large assortment of presentations on ecology, which can be downloaded absolutely free of charge. To do this, you need to go to the selected presentation and click on the "download" button. Before that, you can see each slide and view their description, you do not have to download the files first and only then realize that this is not quite what you need. If you have difficulty finding the topic you need, you can use the search for all presentations, enter a keyword and we will select the most suitable works for you.
Here you will find presentations on ecology for both elementary and high school students. Thanks to the clarity, colorfulness of the slides, correctly structured and divided into blocks of information, the audience will be easier to perceive the subject and better concentrate on the topic.
