2. Show students' works:
Liu Mingcheng: In our class, there are also many students who are not afraid of difficulties in scientific and technological production and never give up. Please wait below.
Students take out their own small productions and introduce their own works.
3. Poetry reading "We Love Science"
Rolfe: It seems that the students are really capable. They can not only imagine, but also make their own. This is an exercise. These students know
Small production takes a lot of time and energy, but as long as you persist and are not afraid of failure, you can use your brains and do more.
Scientists thus tasted the joy of success. I hope other students can learn from it. I hope everyone can be good children who love science.
Son! Listen to the students' poem: "We love science"
We love science.
W: We love science, and loving science makes us smarter.
M: We love science; The love of science makes us elves;
W: We love science. We dare to climb the highest mountain.
M: We love science; No matter how difficult the palace is, we dare to explore it.
W: Let's use our brains.
M: Let's make use of our technical skills.
Join: shoulder the heavy responsibility of the new era and create a better tomorrow. 4. Fantasy wild game (props: boxes, puzzles, etc. )
Liu Mingcheng: Give you a chance to use your imagination and practice. Shall we have a game? The title is "fantastic"
Want to compete in the wild ",each group has a box on the table, which contains some spare parts." We divided the class into red teams. "
There is also the blue team. Please come to the stage and see which team can use their imagination to piece these parts together into an interesting work. (team pay)
Stream engineering)
Luo: You see, the works created by students through imagination and joint efforts are so interesting, as long as you pay more attention at ordinary times.
I want to observe, think and practice, and I can create more interesting works in the future.
Liu Mingcheng: Although the competition is over, our imagination and practice have just begun. We should not only dare to think, but also dare to do as scientists do.
I hope I can create more inventions for science in the future and become a useful person! Let's sing a children's song "I have two"
A piece of treasure: the whole class sings together:
I have two treasures, my hand and my brain.
Hands can work and brains can think.
Hands without brains can't learn well.
You can't learn skills without thinking.
Only with your hands and brain can you create.
Creation depends on labor, and it all depends on hands and brains.
Combination: "Imagination+Practice = Creation"

Students, today's "technology is around" theme team is very successful. Students not only actively participated in the activities.
Moving and exercising organizational skills, the teacher was delighted to find that the students' awareness of science and technology has improved. Yes, science assigned it to us.
It is science that has opened the window of wisdom for us to clear away the fog. Because science has brought us new creative thinking, because
Because science teaches us the most advanced ideas and methods. Advocating science, let us face this new moon more calmly and objectively.
In a different world, let's plug in the wings of science and soar to meet a better tomorrow!
Third, announce the end of the activity:
Class 1 (1) theme class meeting is over, thank you!
Attachment: eggs hatched by Edison
Today we tell the story of scientist Edison.
Edison always asked questions when he was a child. "What is this?" "What's that?" He is a clever boy.
When Edison was five years old, one day, when he saw the hen at home, he kept staying in the nest and shouted for it, but the hen cocked her head and blinked, and did not move.
What's going on here? Edison picked up the hen and looked at it. Hey, there are a dozen eggs in the bird's nest. Count it. Strange, did this hen lay so many eggs today? He jumped up and down and ran to ask his mother.
"Mom, mom, the hen laid a dozen eggs today. What is this? " "Hens don't lay eggs, but they are afraid of catching cold." Mother held Edison in her arms and said, "Mom holds you, aren't you much warmer?" Edison is even stranger. He stared and asked, "Mom, eggs are just like us. Will they catch cold? "
Mother smiled and told Edison that the hen was hatching eggs. The hen covers the egg with her own body, but it is much warmer, but inside the egg, a chick will grow, with a small mouth, feet and feathers. Later, the chicken grew up, pecked through the eggshell, chattered and came out of the eggshell.
Edison listened to his mother and ran away. Where did Edison go? An hour later, my mother didn't see Edison. How anxious she is! Looking around, ah, Edison went to his neighbor's house. He made a nest out of firewood and put many eggs in it. He squatted on the egg like a hen! He thought; When a hen squats on it, it will hatch a chick. When I squat on an egg, it will definitely hatch a chick.
When mother saw Edison's stupidity, she was really amused. She pulled Edison up and said, "Come on, silly boy, you can't hatch chickens."
Edison pouted and said, "Mom, hens can hatch chicks. Why can't I? "
Children, please think about it. Can Edison hatch a chicken by squatting on an egg?
Attachment: experimental content
1. Add salt to the eggs in the water and they will float.
Principle: Put the egg into the water and sink first. When salt is added to water, it becomes brine. As the density increases, the buoyancy of the egg increases, so the egg will float. This is a beaker. (Pick it up and show it to the students. ) I put the egg in a beaker. Look, the egg has sunk. You see, I slowly add salt to the water and stir it with chopsticks to see how the eggs look. Eggs will float. The reason is that when an egg is put into water, gravity is greater than buoyancy, and the egg sinks. After adding salt to water, it becomes salt water, which increases the density and the buoyancy of eggs. At this time, the buoyancy of the egg is greater than gravity, so the egg floats. )
2. Chopsticks pick up rice
For this experiment, prepare a chopstick, a cup of rice, water and a cup. First put more than half a cup of rice in the cup, then put the chopsticks into the cup, then take some water into the cup, then press the rice next to the chopsticks with your hands, and finally lift the chopsticks, and the rice will be lifted. The added water makes the rice grains in the cup expand rapidly, and the rice grains squeeze each other, so that the air in the cup is squeezed out, and the pressure outside the cup is greater than the pressure inside the cup, so that the chopsticks and the rice grains are closely combined and the chopsticks can lift the cup filled with rice. )
We love science.
W: We love science, and loving science makes us smarter. M: We love science; The love of science makes us elves; W: We love science. We dare to climb the highest mountain. M: We love science; No matter how difficult the palace is, we dare to explore it. W: Let's use our brains.
M: Let's make use of our technical skills.
Common: shoulder the heavy responsibility of the new era and create a better tomorrow.
I have two treasures:
I have two treasures, my hand and my brain.
Hands can work and brains can think.
Hands without brains can't learn well.
You can't learn skills without thinking.
Create with your hands and brain.
Creation depends on labor, and it all depends on hands and brains.
Combination: "Imagination+Practice = Creation"
