stem competitions for elementary students

Here are some examples of primary school science being integrated into STEM teaching: 1. **"Making Colorful Ramen" course **: - It was designed based on the "Water" unit of the third grade of the textbook version of the primary school science. - ** Science **: - Understand the definition of water solution, learn how to prepare water solution, and discover the law of color change of water solution. - Know the cyanidins (such as eggplant, purple cabbage, etc.), know the effect of different solutions on the color of the purple cabbage solution, and then judge the ph of the solution (the solution that can't make the purple cabbage solution change color is a neutral solution, the solution that can make the purple cabbage solution turn red is an acidic solution, and the solution that can make the purple cabbage solution turn blue or green is an basic solution). - ** Technology **: - Practice using a pH-meter to measure the pH-value of the water solution and compare it with the color change of various water solutions after adding litmus paper. - Able to use the correct tools during the process of making colored ramen. - ** Engineering **: - Using the characteristics of acid and base to make food appear in different colors, experience the combination of life and science, explore and solve the problems encountered in daily life in the natural environment. - Experienced in engineering design, willing to cooperate and communicate with peers, design plans and modify them, strictly follow the design steps and procedures to complete the scientific practice of making colorful ramen, and solve problems through creation. - ** Mathematics **: - Understand that the range of pH-values is from 0 - 14, with 7 being the middle point. - Accurately measure the solution's pH-value and judge the solution's pH-base. By comparing the pH-value, one can understand the pH-base of various water solutions (when the pH-value is <7, the solution is acidic; when the pH-value is>7, the solution is basic; when the pH-value is =7, the solution is neutral). - The experimental materials included a juicer, a pH-meter, an electronic scale, a beaker, a glass rod, litmus test paper, disposable gloves, blotting paper, a measuring cylinder, a funnel, an iron stand, filter paper, a rubber head dropper, a measuring flask, a rolling pin, purple cabbage, Sprite, apples, lemons, milk, flour, baking soda, white vinegar, and so on. - The activity began with the extraction of the purple cabbage solution in Class 1. The students were asked to understand which foods had cyanidins according to the pre-prepared knowledge, think about the way to dissolve cyanidins, form an inquiry question, review the definition of water solution, and discuss whether the cyanidins in the purple cabbage juice would be destroyed by high temperature. 2. **'Why Can't Clothes Dry' Course **: - Through the setting of the scene, he used the phenomenon of clothes not drying due to continuous rain in his daily life as an entry point. - [Knowledge and Skill Target: To let the students know the method and principle of removing water from clothes, and understand the working principle and basic structure of the drying machine.] - ** Method and process objective **: To enable students to design a water removal plan and make a simple drying equipment for experimental verification, and to be able to discuss the best plan based on the evidence obtained. - ** Emotional attitude and values goal **: Let students actively cooperate with others in activities, actively participate in exchanges and discussions, be realistic, and be willing to share. - The curriculum was designed based on a question-based model. - The experimental equipment included a small fan, a small electric stove, wooden strips, rubber bands, cloth, and so on. - The students were guided to analyze the possible reasons why the clothes could not dry, such as the clothes hanging outside and getting wet, the clothes were too thick and wet, the weather was too cold, and the water was not easy to evaporate. Give the students enough space to think and brainstorm. During the discussion, emphasize that letting the clothes dry is to separate the clothes from the water. Let the students find out the state of water (solid, liquid, gaseous) through searching for information, and then guide the students to think about how to let the water in the clothes evaporate into the air in gaseous form. For example, wring the excess water from the clothes by hand, blowing the clothes with a small fan, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Mexican primary school students actively participated in various activities, showing enthusiasm and vitality for multiculturalism. In terms of language learning, many primary school students were keen to learn Chinese. For example, the children of Queen Elizabeth School in the south of Mexico City actively participated in activities such as speaking Chinese, singing Chinese, and writing Chinese on the occasion of "United Nations Chinese Day". They showed their talents and love for Chinese by writing calligraphy, playing paper-cutting, speaking Chinese tongue twisters, singing Chinese songs, and dancing the Northeast Two-person Rotation. The school was a private primary school in Mexico City. It had been teaching Chinese for many years and regularly organized various activities related to the China language and culture. The children loved China culture and were passionate about learning Chinese. At the same time, in the finals of the "Chinese Bridge" World Primary School Chinese Language Show in Mexico, 18 young contestants from all over Mexico participated in the competition.

The kindergarten was a stage of pre-school education. This stage was extremely important for the growth of children. For example, it played a decisive role in building the structure of the child's brain nervous system. It also largely determined what kind of person the child would become in the future. Primary school was a compulsory education stage, and it was also a part of primary education. This stage was the key period of education. While learning simple knowledge, one had to correct one's moral conduct and establish correct codes of conduct. Junior high school was also a compulsory education stage and was also a part of primary education. This stage continued to play an important role in children's knowledge learning and moral cultivation. For example, further education was carried out on the basis of the early stage, laying the foundation for subsequent higher education. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were indeed some seemingly simple but confusing questions in primary school mathematics. For example, the problem of repairing bricks. The existence of half a brick might confuse the child. It was necessary to observe the arrangement of the bricks, first calculate the number of bricks in a complete row, then calculate the number of bricks in the empty row, and then use the number of bricks needed in each row to subtract the number of bricks in the empty row. Finally, the number of bricks in each row was added to get the total number of missing bricks. The question of knowing the direction was a test for the spatial thinking ability of the third grade children. When the spatial imagination ability was limited, they could use children's songs to remember the method of direction judgment. The process of solving equations using the properties of equations was long and tedious when they first started learning. Although the shifting method was short, it was easy to make mistakes. There were also calculation problems that included a variety of situations, such as the first grade addition and substitution calculation method, the memorization of multiplication pithy formula, and the proficiency in three-digit multiplication of one-digit numbers, two-digit divisions, decimals, and simple calculations. In addition, questions like A multiplied by B equals 16, A multiplied by A equals 8, and B multiplied by B needed to be solved by finding the relationship between A and B. There were also controversial questions about the concept of repeating decimals, and different people would get different answers. These questions might be difficult for primary school students, but for graduate students, due to their long-term exposure to advanced mathematics knowledge, when faced with these questions with unique elementary school logic, they might also be difficult to answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
