One day during the summer vacation, it was very hot, and I heard from adults that drinking salt water can cool down. I thought: on such a hot day, I can turn the salt water into a "salty popsicle"!

I put about half a cup of water in a cup with a pinch of salt in it. Since I was making a popsicle, I put another chopstick in the cup to use as a stick.

An hour, two hours, three hours passed, and I took out the ice salt water from the refrigerator, but it didn't freeze. So I put it back in the fridge and was ready to take it out in a few hours.

An hour, two hours, and another three hours passed, and I took the ice brine out of the fridge again. Hey? It's been six hours, why hasn't it frozen?

Dad, my salt water has been freezing for six hours, why can't it freeze? I asked anxiously.

Dad said, "Because the freezing point of salt is high." When it snows, sprinkle salt on the ground so that the road surface is not easy to freeze.

Seawater is salty, so it does not freeze easily. ”

Oh! I see! I didn't expect to learn such knowledge by making "salted popsicles".

On Saturday, I found a small oil drum on the side of the road, and there was half a barrel of oil in the barrel, and when I turned my head again, I found a large number of ants eating people's ice cream sticks, about 100 or so, I heard that ants are the most afraid of mothballs, and I also want to try whether ants are afraid of oil.

At first, the ants were moving around, but after less than 30 seconds, they didn't move, I picked up a small wooden stick, moved the ants, and put them on the ground, and the ants didn't move, they were dead.

I dug the ant hole, caught a few ants and put them in a small bottle, and when I got home, I opened the cabinet to look for mothballs, and after looking for a long time, I found them, and I put them in the small bottles, and the ants were restless, but they didn't die.

I turned on the computer and checked, and it was said on the Internet: "Ants are most afraid of oil, because once it falls into oil, it is like a person falling into a swamp, and it dies quickly; But mothballs don't kill ants, but ants only have an aversion to it. ”

Suppose I am a tree.

If I were a tree, I would let the homeless birds fly to my body, let the birds build a nest on my body, I would shelter them from the wind and rain, and when the weather was fine, I would let these birds sing and dance on my branches. Let them live happily every day.

If I were a tree, I would become a talking tree, and I would put a garbage can next to me, and when some people passed by and wanted to throw away their garbage, I would warn them: "Don't litter, put the garbage in the designated garbage can, so that the earth will be more beautiful!"

If I were a tree, I would hang a lot of small lanterns on my branches, and at night, whenever someone passed by, I would turn on the little lanterns on the branches so that those who passed by could see what was in front of them.

If I were a tree, I would let my little helpers, the small leaves, help me collect a lot of sunlight and moonlight, and in winter, I would release the sun's rays and make people feel very warm; If it's summer and it's hot, I'll release the moonlight and let the hot summer slip away.

If I were a tree, I would bring a lot of good to humanity. Because it is human beings who give me hope of survival, I will always repay them.

Today is my birthday, and the whole family is in the air of festivities. To celebrate my birthday, my pregnant aunt traveled thousands of miles back to Fushun; My mother bought me a sweet cake; Dad bought me a good remote control car; My grandparents sent me good wishes ......

At 3:20 p.m., my mother cut open the package and took out the cake, and my grandfather brought the fried vegetables. When everyone sat down, I carefully put eight candles on the beautiful cake, Dad lit the candles, turned off the lights, and everyone sang a beautiful birthday song for me, and then I blew out the candles, closed my eyes and made a wish......

After eating the cake, I looked out the window, and the sky seemed to be exceptionally blue; The sun seemed to shine brighter. I can't forget this day, I can't forget my happy birthday.
