science and inquiry

The activities of scientific inquiry about sinking and floating in kindergarten are the important contents of scientific education for children. ** 1. Activity Target ** 1. ** Awareness goal ** - Children need to know which things sink and which float in water. For example, metal objects such as paper clips and nails would sink when placed in water, while wooden and plastic objects such as foam, chopsticks, and wood blocks would float when placed in water. - Able to record experimental results with specific symbols (such as up for floating, down for sinking). 2. ** Ability Target ** - To develop the child's observation ability. Through observation, he can discover the ups and downs of different materials in the water. - Cultivate children's cooperative inquiry ability, such as communicating and cooperating with each other in the process of discussing and guessing the ups and downs of objects. - To train children's ability to record experimental results with symbols, as well as the ability to boldly describe their own operation process and results. 3. ** Emotional goal ** - Arouse the child's desire to explore and satisfy the child's curiosity about the phenomenon of sinking and floating. - Let the children experience the joy of ups and downs or experiments, and feel that science is around them. ** 2. Event preparation ** 1. ** Material preparation ** - The common experimental materials were a basin of clean water, various items made of different materials, such as open cans, sealed cans, bottle caps, plastic blocks, wooden blocks, screws, erasers, wooden blocks, iron spoons, ping pong balls, stones, sponge, glass balls, keys, boats, snowflakes, foam, paper clips, plasticine, and so on. He also needed an experiment record sheet, an empty plastic bottle, a plastic bottle with heavy objects, a number of dry rags, a transparent plate with clear water, and a number of experimental basins for children to do experiments. 2. ** EXP preparation ** - Children should already recognize several common objects made of different materials and have experience in freely floating in the water. ** 3. Activity process ** 1. ** Introduction Stage ** - By showing some common objects, such as keys, boats, etc., it can arouse the interest of children in the phenomenon of sinking and floating, thus leading to the theme of the activity. 2. [Conjecture and Record] - First, let the children make guesses about the floating and floating states of various experimental materials in water, and record the results of the guesses. For example, the child could guess that the wooden block would float and the screw would sink. 3. ** Experiment verification segment ** - The child put the materials into the water one by one to verify if his guess was correct and record the actual result again. During this process, the teacher would observe the results of the children's operation and guide and encourage the children who were slower. For children's different opinions (like an object, some children think it is heavy, some children think it is floating), they can unify their understanding through experiments. 4. ** Exploring and changing the ups and downs ** - Let the children try to explore how to make sinking objects float up and sinking floating objects. For example, if a solid plasticine sank in water, a child could change its shape to make it float. During this process, the teacher encouraged the children to try the operation and guided them on a tour. 5. ** Summing Up and Extending Stage ** - The teacher made a summary and summarized the knowledge about the ups and downs of objects in water and the materials of the objects themselves. It could also guide children to migrate their life experiences and look for the phenomenon of buoyancy in life, such as ships, swimming rings, bamboo rafts, and other examples of using buoyancy. The activity extension part allowed the child to look for other objects that could change the floating state by changing their shape or using external forces, and try it out through experiments. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The entrance to the National Computer Level One Results Inquiry System was the China Education Examination Network (<anno data-annotation-id ="00000000 - 4114 - 4414-a116 - 80111100000"></anno></anno>(<anno data-annotation-id ="23333308 - 44440 - 44000 - 4000 - 8000000000000"></anno>). Examinees could log in to the "Results Inquiry" section of the website to inquire about their results, and log in to the "Certificate Inquiry" section to inquire and download their electronic certificates. You can also register for the China Education Examinations Network account to inquire about the 1994 and later examination certificates and other information.

The sun stem is the heavenly stem on the lunar calendar. It can represent the person seeking to measure himself and his condition in the four pillars. For example, the middle Gui of Guimao is the sun stem, and the middle Gui is the earth branch. It was the axis or core of the four pillars, and the inferences of the Lord's various astrological phenomena were mainly carried out around the sun. The sun was divided into ten heavenly stems, namely A, B, C, D, E, Ji, G, Xin, Ren, and Gui. There was a concept of prosperity and decline of the sun, which was divided into several situations such as obtaining orders, obtaining land, obtaining life, and obtaining help.
