The experiment - a safe way of understanding reality and an effective observation exercise

The experiment - a safe way of understanding reality and an effective observation exercise

       It may seem odd, but after a certain age, man does not know to observe everything that is happening around him, or he does not have time for it. He does not see details, and curiosity is no longer high.
      Children are more curious than adults, and this is a good opportunity to form an active attitude towards the environment. Their curiosity can contribute to an effective observation of all phenomena, of the surrounding reality. With little help, children can see things that an adult can ignore.
          The observation spirit, the curiosity, the desire to know are just some of the conditions underlying the learning by using the experiment. The experiment can create favorable emotional states, can lead students to use their experi- ence experiences and other activities.
      Especially in environmental knowledge activities it is very important to use the experiment. Ideally, every experimentation activity should be used at the time of introduction of the lesson, to stimulate students' interest in new information, during the lesson, to deepen knowledge or to provide feedback.
        By using the experiment, learning becomes more solid, the preschool actively participates in learning, observes, questions, questions, finds some answers on its own. Also, the spirit of investigation is formed and developed, students acquire the ability to formulate hypotheses, to verify them. By realizing an experiment, the child acquires some practical skills, develops logical thinking, creativity.

The experiment - practical example
The theme of the day - "Water - the miracle of life"


     The experiment is a didactic teaching-learning activity that explains the causes of a phenomenon by using action-intellectual operations. Using this method, we sought to stimulate interest in experimental research and communication of group learning outcomes.
Target operational objectives:
explain the origin of the water (springs, rivers, rivers, fountains, rain);
§
To formulate hypotheses for experiments;
§
To formulate conclusions and verify whether the experiment responds to the hypotheses formulated at the beginning;
§
Acquire basic knowledge about the economic importance of water (hydropower, transport, etc.);
§
Verbal expression of causal links;
§
Understand the need to preserve water quality;
§
Describe environmental behaviors (economic use of water) and ways of combating pollution;
§
Record the results of the experiments graphically;
§
News of the day:
     Through its adventures towards the land where the flower-spiders live, Degetica, it goes through different natural environments: it knows the water and some of its inhabitants, knows the cool depth of the soil, it passes through the air borne by the saving ranch. All of these places are wonderful, each with its role in nature; however, man sometimes breaks the charm of nature, and water is most exposed to man's unhappiness. The fist urges the children to check the purity of the water in the environment they live in and to make a "Green Code" that they will respect daily with their friends and family.
      Degetica suggests some evidence to children to be sure they are ready to become researchers. Following the successful passing of these tests (Environmental Knowledge), they will receive the required dressing gowns in the lab, with the labels that designate the team they will be part of.
      In order to test the quality of the water collected in the Danube and the one added from the filter mounted in the kindergarten hall, the children are divided into three teams according to the badges attached to the dressing gowns.
1. The Rainbow Team
The first team will simulate the formation of the rainbow by passing the rays of light through the clean water and through the water taken from the Danube. Children first formulate hypotheses, perform experiments, then record the results in the observation sheet with the drawing.
Required materials: large transparent glasses, lanterns, mirrors, white cardboard.

2. The second team, the one of the "crystalline drops", will put in blue water tubes (ink) the following sketches: in the first drop, in the second - 2 drops, in the third - 3 drops in fourth - 4 drops. The experiment was repeated in dirty water tubes in the Danube. The children will formulate assumptions, then record the results in chips (by drawing). They will formulate oral conclusions: we can not get tones for beautiful paintings except in clean water, we can not wash, can not wash fabrics, etc.
              Required materials: test tubes, staples, pipettes, ink, data logs.

3.The aquatic life squad
     The third team produces two identical filters (wadding, gravel, then sand) in transparent plastic bottles cut in half, with the neck down. The water from the two sources is passed through the two filters. They will formulate assumptions, record results, and draw conclusions.

CONCLUSIONS:
Polluted water passes through the body of fish leaving traces, as it left traces in the filter; fish get sick.
§
And our internal organs suffer when we consume dirty water - polluted water damages the health of all the living;
§
Due to the water circuit in nature through its transformations (evaporation, precipitation condensation - which we experienced at ALA 1), the polluted water penetrates everywhere: air, soil, life, destroying the balance of nature.
§
Think about situations where you can save water and improve your quality. Apply beautiful images on the workspace "
§
"Green Code"
Again on teams, keeping the component, the "Green Code" (Practical Activity) will be prepared, using the chips selected by the children from the ones provided by the educators, using the observation sheet drawn up following the experiment. Each team makes a poster based on the conclusions. We will illustrate rules that we respect with friends and family to protect the environment
§
The posters are exposed, the groups of children pass on to each exhibit, then return to the original place and re-examine the product in the light of the observations made ("Tour of the gallery").
§
The day ends with ALA 2 - drama "Degetica" by H. Ch. Andersen. The emphasis falls on the diverse natural background of the heroine, pointing to the importance of water, its purity and its necessity for all living things.

Panda

The panda , also known as thegiant panda to distinguish it from the unrelated red panda, is a bear native to south central China. It is easily recognized by the large, distinctive black patches around its eyes, over the ears, and across its round body. Though it belongs to the order Carnivora, the panda's diet is 99% bamboo.Pandas in the wild will occasionally eat other grasses, wild tubers, or even meat in the form of birds, rodents or carrion. In captivity, they may receive honey, eggs, fish, yams, shrub leaves, oranges, or bananas along with specially prepared food.

The giant panda lives in a few mountain ranges in central China, mainly in Sichuanprovince, but also in the Shaanxi and Gansu provinces. As a result of farming,deforestation and other development, the panda has been driven out of the lowland areas where it once lived.

The panda is a conservation reliant endangered species. A 2007 report shows 239 pandas living in captivity inside China and another 27 outside the country. Wild population estimates vary; one estimate shows that there are about 1,590 individuals living in the wild, while a 2006 study via DNA analysis estimated that this figure could be as high as 2,000 to 3,000.Some reports also show that the number of pandas in the wild is on the rise. However, the IUCN does not believe there is enough certainty yet to reclassify the species from Endangered to Vulnerable.

While the dragon has often served as China's national emblem, internationally the panda appears at least as commonly. As such, it is becoming widely used within China in international contexts, for example the five Fuwa mascots of the Beijing Olympics.imagesGrosser Pandadescarga
