Small paper on scientific and technological invention and creativity 1
It was the summer vacation of grade four, and I had finished a lot of homework. It's just that the small production of this homework makes me nervous. Once, I accidentally saw a box of expired "Sanjing Brand Blue Bottle Oral Liquid" in the living room. I went over curiously and opened it. Full, I only drank one bottle! I want to drink these delicious oral liquids, but they have expired. What if you are embarrassed to throw it away? I had a brainwave: "I can dump the expired oral liquid in the bottle and collect the bottles outside to make a beautiful wind chime!" " " .
To start, I'll take the bottle out of the box first, stab a small hole in the bottle with scissors, then put the bottle down and let the oral liquid pour out bit by bit. After all the oral liquid was poured out, I put the bottle on the table. Find out some cardboard and double-sided tape that are not used in art class from home, and find out tools such as wool and scissors. After everything is ready, production will officially start.
My mind flashed a lot of wind chimes I had seen in the store, but I just didn't know what to do. I found a lot of art books, and finally found the "underwater world" wind chime in the art books of grade three. My mother and I discussed it for a long time and decided to do it.
I cut a blue cardboard into a circle, then cut off an acute angle on the circle, and then glued the two sides of the corner just cut off with double-sided tape, thus forming a funnel shape. Next, we will make pendants. Pendants are all kinds of underwater creatures. I drew a big crab on a piece of red cardboard, holding big and powerful feet and bulging eyes. It looks awesome! I cut it carefully with scissors. Cut a big, fat carp and a small turtle with a thick shell ... and prepare some wool of different lengths and colors and stick one on each creature's back. The second is to hang a bottle under each creature, which makes me wonder. How can I hang the bottle firmly on it? It's not nice to put it directly on the bottle mouth, and the bottle is glass, so you can't make a small hole. What should I do? I looked at the bottle in a daze. Suddenly, my eyes fell on the toothpick on the table. I had a brainwave and came up with a good idea. I divided the toothpick into two sections, picked up one section, tied it in the middle with wool, put the toothpick obliquely into the bottle mouth and lifted the wool. The bottle hangs steadily. I hang all the bottles in the same way. Finally, all the wool connected with the creature and the bottle passes through the center of the funnel and is twisted into a strand. Such a beautiful wind chime is finished. I showed it to my mother, and she loved it. She praised my good work and hung it in the living room with me.
Every time I go to the living room, I look at my wind chimes. Every time it is windy, my wind chimes will sing and dance in the wind.
Small paper on scientific and technological invention and creativity II
In today's society, there are many people with myopia. Although my invention can't cure your myopia, I can help more people stop myopia. People who are not nearsighted can also use it. The name of this invention is multifunctional ballpoint pen.
This ballpoint pen is very special. It has many different appearances from ordinary ballpoint pens. It has the latest chips-intelligent chips, communication chips and listening chips. ...
Although it has very advanced equipment, it also looks like an ordinary ballpoint pen. It looks the same, but there are still several differences-there are buttons and speakers, but there is no start button. What's going on here? If you want to know, just look below!
Very easy to use, let me teach you! If you want to start writing, just press the red button and say to the speaker, "Start using!" " "You can write! If you want to take a break before writing, press the green button, or press the red button and say, "Stop using!" " "Just do it. If you want to continue writing after a break, press the red button and say, "Keep using!" " "Just do it. If you want to turn off the phone, just press the black button.
Hey? If you are not nearsighted, why can't you introduce it? Since you found out, I'll tell you! If your writing posture is wrong, he will have an alarm to warn you, and it will stop warning when your posture is good.
