We. Teachers and students from grades 4 and 5 participated in a science and technology activity organized by the school, and the destination was the Shanghai Youth Activity Center. We set off at 8:30 a.m. and took a bus for nearly half an hour to arrive at the Shanghai Youth Activity Center.
In the morning, we made a solar storage tank at the Shanghai Youth Activity Center. At 9 o'clock, we started our class. The teacher first showed us three paragraphs**, which told us a lot about solar energy:
Solar energy does not pollute the air, can save water and electricity, and is a new energy source that is beneficial to the environment. Solar energy can use sunlight to convert into heat, electricity, oxygen and other energy to meet people's needs in life and production.
Now, we're going to start making solar storage tanks. First, we took a solar panel and all sorts of tools. Then, we need to insert electron 0116, diode D, and diode l into the corresponding jacks.
Next, we plug C1 and C2 into the corresponding jacks. After that, we put the LED light and the ball switch in place, and it will glow. In the end, we just need to glue a piece of cardboard to the back of the solar panel with double-sided tape and put it in a solar storage tank, and it's done.
Through this activity, I learned a lot about solar energy and enriched my knowledge. This activity of making solar storage tanks was really fun and informative!

First of all, it is necessary to clarify the scope of material selection. In particular, it is important to know that activities are purposeful, prepared, and organized, and many people participate in one thing, which can include cultural activities, sports activities, class meetings, team meetings, etc. However, it is necessary to pay attention to the selection of venues to be as distinctive as possible, which requires students to think carefully when selecting materials, and write as much as possible about the activities they personally participate in, or are particularly interested in, or are educated, in a word, the materials strive to be novel.
Second, write down the order of activities clearly. General activities should be prepared, processed, and outcome. If you write them all, it will be bland.
Therefore, when writing, you should determine what is required or emphasized, and what can be left unwritten. In particular, content that is not relevant to the center can be omitted, otherwise it may become a running account. Write activities can be written chronologically or in the order in which the place is transitioned.
Finally, share your own feelings during the event. When you participate in a favorite activity, you will naturally have some experience, you may learn something, and you may have some sense of joy in life. It would be great if you could write down the knowledge and feelings you learned from the event, so that everyone can also feel educated and share the joy with you!
Maybe you can achieve the goal of better educating yourself and infecting others. And pay attention to be sure to write your own real experience, and do not write empty words in the form of slogans.
