How do primary school students make their own meteorological experiments

There are many ways for pupils to do meteorological experiments by themselves.

1, rainbow rain in the bottle. Materials: transparent glass, shaving cream, colored pigment, dropper. How to play: first fill the container with half to two thirds of water, not too full. Squeeze a lot of shaving cream on it. Prepare several different colors of pigments or pigments and mix them with a little water. Drop the color on the cloud with a dropper and see how the color soaks into the water and spreads.

2. Artificial fogging. Material: a jar and a piece of dry ice. How to play: put dry ice in the bottle, cover it, and wait a while to see the fog in the bottle.

3. Self-made weather vane. Materials: cardboard, pins, wooden strips. How to play: Draw various elements of the weather vane with colored strokes, cut them off and stick them on the cardboard, and finally put the pin through the cardboard and fix it on the wooden strip below.

Knowledge expansion

Meteorology refers to the changes and phenomena of air, water, climate and weather in nature. Meteorological phenomena have an important impact on our life and production activities, so it is very meaningful to learn and understand meteorological knowledge.

First of all, meteorology can help us predict weather changes. By observing the changes of meteorological factors such as temperature, humidity, air pressure and wind force, we can predict the future weather, such as sunny, rainy and snowy days. This is of great help to agricultural production, transportation and daily life.

For example, in agricultural production, farmers can arrange the planting and harvesting time of crops according to the weather forecast; In terms of transportation, airlines can adjust their flight plans according to the weather forecast; In daily life, people can choose suitable clothes and travel modes according to the weather forecast.

Secondly, meteorology can help us prevent natural disasters. Some extreme weather events, such as typhoons, rainstorms and blizzards, will bring great loss of life and property to people. By observing the changing trend of meteorological elements, we can take measures in advance to prevent these natural disasters.

For example, if a typhoon comes, the government can issue an early warning signal in advance so that residents can take preventive measures; When the rainstorm comes, the city can strengthen the construction of drainage facilities to prevent the occurrence of urban waterlogging; When the snowstorm comes, the traffic department can take traffic control measures to ensure traffic safety.

Besides, meteorology can also help us protect the environment. With the development of economy and the growth of population, the problem of environmental pollution has become more and more serious. Some meteorological phenomena, such as smog and acid rain, are related to environmental pollution. By observing the changes of meteorological elements, we can better understand the emission of atmospheric pollutants and provide scientific basis for environmental protection.

For example, the government can formulate more scientific environmental protection policies based on meteorological observation data; Enterprises can adjust production technology and pollution discharge measures according to meteorological observation data; Residents can choose a more environmentally friendly lifestyle based on meteorological observation data.

In a word, meteorology has an important influence on our life and production activities. Learning and understanding meteorological knowledge can help us to better predict weather changes, prevent natural disasters and protect the environment. Therefore, we should pay attention to the changing trend of meteorological phenomena and master the basic knowledge of weather forecasting and the methods and skills to prevent natural disasters.

At the same time, the government and enterprises should also strengthen the construction and maintenance of meteorological observation facilities and improve the level and quality of meteorological services. Only in this way can we better cope with the changing trend of various meteorological phenomena and ensure the safety and sustainable development of people's lives and property.
