Summer vacation diary 400-word primary school

1, summer vacation experiment diary

On this day, I bought a very interesting book, which is full of classic science games. Very beautiful. On my way home, I read this book again and again. The first time, the eyebrows were knotted, and the second time, the mouth was wide open? o？ Font, the third time, my eyes almost fell out, because the content of this book is so wonderful that blowing air can freeze good juice, so wonderful that it can blow out square bubbles like magic!

When I got home, I immediately ran into the study, chose the simplest game and did as the book said.

I first found two books about the same size as the number of pages and laid them flat on the table, the first one facing up and the second one facing down. Then I lifted the corner of the book and overlapped the two books every ten pages. The book says that when performing in a general magazine, every page should be folded together, and the book should be folded every 10 page.

The experiment was carried out step by step, and soon, the two books staggered one page every ten pages. I gently pulled two books for the experiment along the horizontal direction written in the books, but I couldn't open them! Pull hard, it won't open! Pull hard, but it won't open! Strangely, the two books are glued together, although they are not glued together.

Why? It turns out that atmospheric pressure will make paper stick to paper, and there will be friction between paper and paper. Although the friction of a piece of paper is not great, the friction of the whole book is great. If every page of the two books is staggered, it is enough for adults to open it!

This experiment made me feel the power of science. I like science and I like this book.

2, summer vacation travel notes

Day 1: June 30th.

Now, it is the afternoon of June 30th, and I finally set off for Longquan.

The long journey lasted four and a half hours, but I was still very excited. Finally, I arrived at Chen Guang's apartment in Longquan. It's a pity that it's getting late, so I'll wash and sleep today.

The next day: July 1

It's sunny in Wan Li, but it's a little hot. After all the staff arrived, we set off for Longquan's famous celadon museum.

When I got there, I saw this museum. It looked like a huge kiln. Looking forward to it, I hurried up the stairs and the first thing I saw was the topographic map under my feet. A little further inside, the scenery here makes me shine. There are many celadons of different ages: Five Dynasties, Tang Dynasty, Song Dynasty and modern times, and there are also many celadons with different uses: plates, chairs and incense burners! Further inside, the production process of ancient celadon is simulated and vividly displayed in front of you. Here, I learned that the production process of Longquan celadon specifically includes the following steps: earth borrowing, crushing, elutriation, mud refining, molding, air drying, blank cutting, decoration, plain firing, glazing, boxing, kiln loading and firing *** 13.

After that, we went to White Swan Villa for dinner, and then we went to Yufeng Villa for a happy evening.

Day 3: July 2.

I got up early today and climbed fengyangshan, the first peak in Jiangsu and Zhejiang.

Fengyangshan is a primeval forest. The tour bus took us a short way. As soon as we climbed the steps, we heard many cicadas chirping. In the next hour and a half, we caught a lot of cicadas, but we let them go. Just as we were sweating all over and preparing to go down the mountain, we reached the top of the mountain at an altitude of 1929 meters. Sitting on the top of the mountain, we rallied, ate something and went down the mountain with sore legs and feet. After going down the mountain, we also went to see Tongxin Tree!

In the evening, we went to KTV to sing. My mother and I prepared snacks for Le's driving tomorrow.

Today, as soon as we got back to the hotel, it was difficult to get up.

Day 4: July 3rd.

Today is the day when I will go back to Wenzhou.

We went to eat delicious fat fish heads, looked at the quaint ancient covered bridges and went home.

3. My travel diary

Although not as good as Maldives and Aegean Sea, as long as there is sea, it is enough happiness. In the summer vacation, I went to Pingtan.

I never believed that the sea was salty and bitter, but today I do. Although I have been to many places since I was a child, I have never been to the seaside. Today, facing the vast sea, listening to the sound of the waves and feeling the sea breeze, I finally feel the vastness of watching the sea. Watching the coast pierce the waves, leaving traces of salt water, still can't stop its attraction from entering its arms. When I walked into the sea, there was a little more salt in my mouth, and I licked it gently. It was as salty as Meng Jiangnv's tears. It turned out that the sea really shed tears. Floating on the sea, pushed by white waves, like flying fish. Look at the sand floating in the water, just like clouds. The sea is so beautiful, no wonder seagulls stay.

I never believed that the stars would twinkle, but today I do. At 4: 07 in the morning, my sister and I went to the seaside to watch the sunrise. Looking at the sea, it's as dark as if Pangu never opened heaven and earth, and the sky and the sea are muddy, leaving only a trace of waves tearing black and white. The rapidly divided sea, because of the failure of the waves, quickly turned into the sky. Looking up at the sky, the stars will really blink, and perhaps the magnificent buildings without cities will be particularly clear. I can't find the moon. I only see stars like fireworks. I can't find the sun. I only see the sea like night. The lighthouse on the distant island is as bright as a star, as if the sea is a mirror of the sky, and there are really sparks sleeping in the sea. Waiting is really boring. I can only watch the clock chew the time, chew it up, spit it out, and then put it numbly in my mouth. For a long time, a light appeared in the sky. It is no longer moonlight, but sunrise. It turns out that the sun is so promising, and watching the sun slowly push open the curtain-like clouds makes me feel very warm. Sunrise. Scattered sunlight hits the waves, and the clouds are unconsciously painted orange. It is still the beauty of sunrise, giving people light.

Time is really unreasonable, the tide recedes, people disperse, and it is night, and the day is over happily.

4. Have a nice trip to Xiamen

Just after the summer vacation, my parents took me to Xiamen and started a happy trip to Xiamen.

As soon as we arrived in Xiamen, we were immediately attracted by the unique coastal scenery. The blue sky is so blue that it looks particularly high. As blue as the sky, it is an endless sea. The sea is very calm, occasionally turning up a few small white waves, golden. The beach is warm and bright under the scorching sun. On the coastal road, rows of big trees grow very luxuriantly, and people who take a leisurely walk can always be seen under the trees.

Although the weather is hot, the burning sun in Xiamen can't stop our enthusiasm. I am like a happy bird, not to mention how happy I am. Tasting all kinds of delicious food in Gulangyu, taking photos under the statue of Zheng Chenggong, riding a bike on the seaside avenue, digging holes and piling sand on the beach to blow the sea breeze, all left us with laughter everywhere.

I will never forget that happy trip to Xiamen!

5. Nanjing tourism

One day in the summer vacation, my mother took my sister and me to Nanjing to play. Early in the morning, we arrived at the railway station and set off by train.

After more than an hour's train journey, I finally arrived in Nanjing. Nanjing has many scenic spots: Confucius Temple, Sun Yat-sen Mausoleum, Zhonghua Gate, Xuanwu Lake and so on. My favorite thing is to go boating in Xuanwu Lake. The weather is very hot. We arrived at Xuanwu Lake. My mother bought a boat ticket and we got on the boat. This time, I became the team leader. The boat is electric, so I don't need to row. I just need to master the steering wheel, forward and backward. I'm excited to take everyone with me. Although the weather is very hot, I feel a little cold on the lake. The scenery by the lake is very beautiful. The lotus leaves in the lake are green, and the lotus flowers are gradually blooming, white and pink. A gust of wind is blowing, which is really comfortable!

I am really happy today! I hope to come again next time.
