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>

An example of a beautiful sentence from a primary school student is as follows: What is failure? Nothing is just a step closer to success; what is success? After walking all the roads leading to failure, there was only one road left, and that was the road to success. May you carry forward your optimism and persist in your beliefs in life, because good luck will always come to you. If I say if you are a small fish, then in front of my eyes will be a sea, I swim towards you, I get close to you, I feel the joy of fish and water, I see your curiosity towards me, your friendliness towards me. Life is not about waiting for the storm to pass, but learning to dance in the rain. The sea is vast because it can accommodate thousands of rivers; the sea is ordinary because it comes from little by little. We shouldn't make fun of those old people who are eager to learn. On the contrary, we should learn from them. Success comes from hard work. Success is the goal that everyone wants to pursue, but success is not something that falls from the sky. It is obtained through one's own efforts and sweat. Success always belongs to those who love to learn and are willing to work hard. Courage is not about not feeling fear, but continuing to do it even if you feel fear.
