Paper airplane competition essay 400 words, the first time to do paper airplane experiment essay

Speaking of paper airplanes, I have a unique affection for them, and I recall playing with paper airplanes in kindergarten. Paper airplanes, a lightweight, convenient toy, it only needs to be done with a piece of paper, it is simpler than any toy.

A piece of paper can become a paper airplane, let's take a look at how a piece of paper becomes a paper airplane: the first step, fold a rectangular piece of paper in half, the second step is to spread out the paper, the two corners of the rectangular paper, respectively, to the center line, fold away, become an isosceles triangle, the third step, turn the isosceles triangle back, and then fold the two bottom corners of the isosceles triangle to the place near the top corner, the fourth step, fold the top corner back, press the two bottom corners, the fifth step, fold the paper in half, and then fold the paper to the center line, A paper airplane was born, and I remembered playing with paper airplanes in kindergarten, so I couldn't help but give this paper airplane a name - Dream, because it was my childhood dream.

How is the Dream performing? Can it move forward? So, the Dream took a test flight, and it flew all the way forward, but it hit the glass and "malfunctioned", which was repaired after a while.

The game began, and one person's plane, just flew to his feet, and came back, it was really a U-shaped turn, and the other directly hit the bottle, and knocked the bottle down, causing everyone to laugh. I'm going to race, but I'm a little nervous. My body leaned back, my hand was thrown, and the plane flew out with a whoosh, and the Dream was like a wave, flying up and down for a while, and my mood was up and down with the Dream at the moment.

Not long after, the plane fell, falling in the middle of the sofa and the electric fan.

Paper airplanes left a deep memory in my childhood.

I stroll, walk as a car.

The rain splashed bubbles on the water, fleeting, like some dreams.

Standing on the bridge, there are already weeping willows, although not dark green, but this green willow is only yellow and semi-uneven state is my favorite, I seem to see the hope and vigor of spring, so that the thin heart gradually plump.

The water is shallow and unclear, for it flows, and although it is a river in the city, there is no smell of decay, which is already joyful. Occasionally, floating leaves flow by, or they come from the Huangpu River.

Someone actually set a net to catch a fish, and he actually caught a fish. Although this is rare, it is only that they have grown up in many rivers injected with domestic sewage, and although they have also grown fat and strong, will the people who eat it have trust?

In the distance there was a small boat, two people on board, one of them driving the boat, and the other occasionally fishing on the river. Looking at their leisurely and calm appearance, I can't help but think of the time when I rowed on the canal in my childhood. The water is as clear as a mirror in the summer of childhood.

Oh, jump into the water from the boat, the water is also sweet, swim to the shore and drill out, will crawl forward with his companions to steal a few vegetables and melons, after washing the dust with water, a punch down, they will burst the silver bottle and splash the slurry, we are happy to chew.

After that, he frolicked in the water again, went ashore to fold some willow branches and weave them into a willow hat, and prepared to go home. Of course, we are experienced, and we will be exposed to the sun for a long time to let the traces of the water disappear. But some of us will eventually become adults.

Recognize it and get a punch ......

Standing on the shore like this, I couldn't help but laugh.

For many, many years, there has never been such a presumptuous entry into the water again. Not only the mountains and rivers we have walked, but even the small rivers in our hometown can no longer be trusted.

When I went back a few years ago, I stood by the river for a long time, because of the mixing of sewage from the paper mill and the yarn-dyed mill, and for many years, the green reeds could no longer grow. I knew the ...... in my heart at that timeWhat is gone is gone after all.

In the rain, I found a moment of fresh soothing in meditation. On such a spring day, although I didn't go to the river, the peach and willow green of spring finally rippled in my heart at such a moment.

In the distance, an old man plays the saxophone, although there are intermittent moments, but there is also a unique rhyme, it should be "Homecoming". In the melodious, I thought that this summer, I should go back to my hometown again.

Hometown, even if there is no spiritual refuge, but the smoke of the hometown, the river of the hometown, the grass and trees of the hometown, have been engraved in the depths of memory, and there is still a trace of warmth when I think of it.

On this rainy day, my heart traveled through its own spring, and the willow branches danced for me, and I couldn't help but step forward and catch one, and I knew that my heart was dancing with them.

At this moment, I am happy and happy, because my heart has opened for spring.
