1. In the early morning, the sun jumped out of the horizon and a red sun hung in the horizon. The sun is like a salted duck egg. At noon, the sun shines in the sky. I look up, but my eyes are narrowed by the dazzling light. I'm curious, why is there such a big gap between the morning sun and the noon sun?

2. I play with my dog. The dog put its head on my knee and let me tease it. When he saw me motionless, he stared at me, his eyes full of prayers. I also looked at the dog directly and suddenly found that its pupils were dilated a lot. Hey, why can the pupil be enlarged and narrowed? Is it elastic?

Eat my favorite Daoxiao Noodles at noon today. Mother is stirring the flour. She poured the water into the basin and kept stirring it with chopsticks. Soon, the flour turned into floc. Harmony, my mother said regretfully, "The noodles are soft and you can't eat Daoxiao Noodles. Let's eat the pull tab. " Don't different wheaten foods have different requirements on the hardness and softness of dough?

There is a stain on the bottom of the wok at home. This stubborn stain is difficult to remove. I brushed hard with steel balls, but I couldn't brush them off. Mom saw it, and she taught me a trick: spread a rag at the bottom of the pot, then mix baking soda, salt and lemon juice together, and finally pour the mixture on the rag and let it stand 15 minutes before cleaning. Stubborn stains are easy to remove. What is the reason?

Every day after dinner, my family will take a walk in the community, and I observed an interesting phenomenon. There is a row of pine trees on the lawn of the community, and the grass leaves under the pine branches are shiny and shiny. I touched the grass with my hand. Where does the grease on the grass come from? Is the pine tree dripping?

Yesterday morning, our family went to the park to play, and everyone walked on a wide bridge. The bridge is very long. Every few meters, there will be a finger-wide seam. Huh? Is this intentional? More interestingly, I put my head out of the railing and a cool breeze came at me. But I put my head back into the railing, but I felt a burning heat. Also on the bridge, why is there such a big gap between the outside and the inside of the railing?

Developing good observation and thinking habits is an important prerequisite for cultivating children's creativity and problem-solving ability. Here are some ways to help children develop good observation and thinking habits:

1. Encourage children to observe and describe: show children some interesting things (such as plants, insects, cartoons, etc.). ) and guide them to detect and describe details so that they can understand the surface and structure of the world.

2. Ask questions and find answers: Encourage children to ask "why" questions and help them explore the answers together. Through observation, reading and experiment, let them understand things from multiple angles and improve their thinking ability.

3. Cultivate observation and thinking skills through toys or games: games such as building blocks, playing puzzles and catching puzzles can exercise children's observation, thinking, problem-solving and hand-eye coordination.

4. Learn in the outdoor and natural environment: There are many things in the outdoor environment and nature that can encourage children to observe and think. Encourage them to discover and explore these things and share their findings and observations.

5. Let children solve problems by themselves: cultivate children's ability to think and solve problems independently, such as assembling toys, cooking and planting by themselves, so that children can improve their observation and thinking ability through practical learning.
