Urgent need for a speech on the scientific concept of development, a speech on science

The title of my talk is "Science is All Around You."

Do you know why sunflowers are always facing the sun? Do you know why ice cream "bubbles"? Do you know why the burning flame always goes upwards? These commonplace phenomena that happen around us contain profound scientific knowledge.

All accomplished scientists are good at grasping some small things around them that seem ordinary but contain scientific truths, conduct in-depth and meticulous research, and finally climb to the peak of science.

The British scientist Isaac Newton was hit on the head by a falling apple and figured out the law of gravitation; British Watt observed that the lid of the kettle after the water was boiled invented the steam engine, and the ancient Chinese inventor Lu Ban's hand was cut by toothed blades of grass and invented the saw ......They are the result of scientific research on the phenomena around them, and these inventions have pushed the history of human civilization forward.

In fact, many of scientists' inventions are inspired by the science around us: boats and submarines come from people's imitation of fish and dolphins; The rocket liftoff uses the principle of jellyfish and cuttlefish recoil; It is a ...... that was invented by people through the study of dragonfly flight

Dear leaders, teachers, and students, do you want me to list more such examples? No, no need! We travel in space, and there is science; We taste delicious food, there is science here; We appreciate the colorful flowers, there is science; We look through all kinds of books, and there are also scientific ...... hereScience is everywhere.

One Sunday, I suddenly noticed my neighbor's big white cat grazing in the vegetable garden. I think it's strange, aren't cats carnivores, how can they eat grass? So he went home and searched the "Encyclopedia", but he couldn't find the reason why the cat ate grass.

From then on, whenever I had time, I would carefully observe the ...... of the big white catThe emperor paid off, and finally, I found that every time the big white cat ate grass, it would pull out thin. I guess: maybe the big white cat eats grass because it has a bad stomach?

Later, this conjecture was confirmed by a veterinarian. I was so happy that I finally gained knowledge through my own efforts!

From this incident, I have learned that as long as we observe carefully, use our brains and hands diligently, and always pay attention to the various phenomena around us, we can find that science is all around us!

Thank you!

Speech "In the World.

Bai is the most diligent female celebrity.

Marie Curie "My most revered celebrity dao - Marie Curie.

Some insiders worship celebrities in order to follow fashion, and this kind of blind worship will lead people astray. Some people revere celebrities, take the celebrities they revere as their role models, and motivate themselves to contribute to the people like them. Confucius said, "See the wise and think together", and people often say:

The power of example is endless", so most of these people succeeded. Everyone, has their favorite celebrities, whether they are worshiped or revered. I am not in favor of outside, I revere Marie Curie.

For thousands of years, beauty has been a woman's highest honor and greatest capital, and as long as you are lucky enough to get this, you don't have to ask for the rest. Marie Curie already had the capital of beauty, but she did not use it, and it was from this point that her self-victory began. In order to do scientific research, she is willing to let acid and alkali eat away at her soft hands, and let the choking smoke blow her beautiful forehead.

Dear teachers and students:

That's not right. Because the method is wrong!
