The so-called world is full of wonders. When it comes to important discoveries, people may think of scientists, which seems far away from our lives. However, as long as you are careful, you can find intriguing scientific phenomena everywhere in your life.
In order to confirm this problem, I began to pay attention to it: I accidentally found that in winter, high wires are always tight; In summer, the wires will hang down. Why is this? So with full curiosity, I looked up information on the Internet. It turns out that this is because it expands when heated and contracts when cooled. The most interesting time-I painted at home, and it didn't take long to paint most of it. In the end, it's only left to tick the line with an oil pen. But I accidentally dropped my pen on my clothes when I didn't listen to orders. So I thought of washing with clean water. I didn't expect it to get dirty. In a hurry, I thought of wiping with a paper towel and boiling water. But I still can't get rid of that hateful stain. I walked into the kitchen unconsciously. I saw the bottle of white vinegar at first sight. I immediately thought: the oil of the oil pen is oily, and the white vinegar is acidic. You can definitely get rid of the oil with vinegar! So I dropped a few drops of white vinegar in the dirty place on my clothes. When it is dry, put it in vinegar-added water. I washed it for a while, and the oil stain was gone! The oil stains that can't be washed out after repeated washing and soaking were wiped off by a few drops of white vinegar. Another time, I accidentally poured 200 ml of oil into the water. I thought, this is terrible. My mother insisted on scolding me. After a while, the oil actually floated on the water! It turns out that the specific gravity of oil is lighter than water. A blessing in disguise is a blessing in disguise!
Give me a pair of eyes, let me see the world clearly, clearly and truly, "I can't help sighing. In this world, there are so many beautiful things worth discovering. I really want to find them all and taste the mystery of this world.
On the morning of April 10, Changshu Tin Troupe came to the school and performed a special sketch of children's ideological and moral education-"Send you a piece of green grass". There are sketches, such as the fox winning the lottery, the hedgehog selling thorns, and the wolf installing a telephone, which I learned from you. Every story contains profound truth, which teaches us to be good children with noble character. In particular, the story "Whose Birthday Is Today" deeply educated me, letting me know that the younger generation should know how to be filial to their elders.
How many children remember their parents' or grandparents' birthdays in real life? How many children will give their elders birthdays? The essay "Whose Birthday Is Today" tells us that the elders have broken their hearts for us, and we should know how to be filial and repay their kindness.
Grandpa in the sketch, seeing the cake on the table, thought that his granddaughter was going to give himself a birthday, giving himself a surprise and being elated. What he never knew was that his granddaughter was having a birthday party for her pet dog and invited many classmates! In order not to let grandpa get involved, the granddaughter swept their fun and tricked grandpa out to eat noodles. Grandpa will come back to get the money because he forgot to bring it. When I heard that the children in the room were having a good time, my considerate grandfather waited silently outside the door so as not to spoil the happy atmosphere of the children.
Granddaughter received a phone call from her mother, only to know that it was grandpa's birthday. Under the mother's criticism and reminder, the granddaughter left tears of regret. Immediately, grandpa's birthday was held in a happy atmosphere. ...
After reading this sketch, I can't help asking myself, have you ever cared about your elders, paid attention to your relatives around you, and celebrated their birthdays? No I don't. I didn't even say a word of concern.
My grandmother is a kind old man. She takes good care of me. Every time I go to my grandmother's house, she always treats me warmly and always smiles lovingly at me. But I didn't notice, and I felt that my grandmother was so annoyed. I remember that when I was a child, I talked about everything with my grandmother. I was very close, but when I grew up, I became farther and farther away from my grandmother and became indifferent. This must have broken the old man's heart!
After reading this sketch, I bowed my head in shame and secretly vowed: I must have a happy birthday for my grandmother!
