Science and technology are gradually produced and perfected with the development of human beings, and the development of science and technology further enhances human practical ability. Making scientific manuscripts will help you understand more scientific knowledge. I brought it to you. I hope you like it.

My dream of science and technology, handwritten newspaper information I. My dream of science and technology
Everyone has their own dreams. I want to be as beautiful as Balala. I want to live a carefree life on the green grassland like Meiyangyang. I want to have the whimsy like little cherry. However, my dream seems far away from me. Not long ago, my grandfather put forward the "Chinese Dream". I finally understand that only by having the Chinese dream can I realize my dream, and only by working hard to realize my dream can I make the Chinese dream more beautiful.
When I saw my uncle and aunt astronauts traveling in space on TV, I was very envious, so I had my scientific dream. If I were a scientist, I would invent a "magic machine". In hot summer, the "magic machine" will absorb some heat and make the weather cool. In winter, the machine can release the stored heat, making the climate warm as spring. In this way, people will enjoy a comfortable life all the year round. If I were a scientist, I would build a rainbow bridge between planets. At that time, people could not only travel on the earth, but also go to the universe to see space.
I believe that as long as I love science since I was a child and study hard, I will become a scientist when I grow up, realize my scientific dream and contribute to the Chinese dream.
Second, technology is at hand.
Science is all around us. If you say "no", it's all wet. As long as you pay attention, you can discover the mystery of science. For example, "the egg is floating!" "Believe it or not, listen to me slowly.
"The eggs are floating! The eggs are floating! " Cheers are still echoing in the classroom. What happened? It turns out that today, Teacher Xu Lijuan took everyone to do an experiment to make eggs float.
As soon as class started today, xu teacher took a beaker, put a spoon in it, and carried a plastic bag with an egg and a bag of salt in it. Everyone is puzzled. What's xu teacher going to do? Everyone's whispering didn't stop xu teacher from doing what he was doing. Xu teacher smiled and went to the podium and said to everyone, "Today we are going to do an experiment to make eggs float."
The experiment began. Xu teacher asked his classmates to drink half a beaker of water. For the first time, he put the eggs in the water and plunged them into the water. Xu teacher picked up the eggs and began to add salt.
It seems that xu teacher wants to have a comparison. The second experiment started. I saw xu teacher put the egg in the water. Like a naughty little goldfish, the egg plunged into the water and floated up again. How amazing!
It turns out that this is related to the density of water. The higher the density, the greater the buoyancy, and the lower the density, the lower the buoyancy. Salt is added to increase the density of water. When the density is high, eggs will float.
I looked at this egg, and it seemed to turn into a Dapeng, which took me to the blue sky of science.
