At the age of three, children began to like reading books on scientific experiments, such as 365 interesting experiments, children's favorite scientific experiments, magic experiments and science in games: the most classic popular science books in Germany. Some experiments are done with dad, but no matter what experiments are done or not, children can clearly remember the experimental steps mentioned in the book and are very organized. At the beginning of this year, my father carefully prepared lessons at home for a week. The content of the class is "magic air", including more than a dozen experiments related to air. Dad really showed his energy as a teacher. There are several reference books on his desk, all of which are scientific experiment books that children often read: 365 interesting experiments, children's favorite scientific experiments and magical experiments. The experimental procedure is clearly written in the experimental book. What dad has to do is to choose interesting and easy-to-succeed experiments, and to attract children's attention, and never let them be distracted! Dad collected a lot of information for this experiment, but it was still not enough. He specially went to Nandamen Department Store, bought a lot of straws, balloons and funnels, and wrote the contents of the experiment to be completed on the children's blackboard. After everything was ready, dad wrote an invitation letter on behalf of the children, inviting the children in their class to participate in the experiment. After that, the father communicated with Yan Xuan, the child's class teacher, and finally decided to send the teacher and the child by the kindergarten park car on weekends. The weekend is coming, and the weather is particularly good. The park bus is full of teachers, parents and children who come to our home. Dad is really capable. He immediately caught the children's attention and began to do experiments with them. He will ask them some questions from time to time. Lovely parents seem to be as enthusiastic as their children. Some carefully write it down and prepare to go home and do it for the children again. Some take their children to explore the mystery of the experiment. The seriousness of parents always infects children. If you don't believe me, please observe in life! Children like having children come to our house very much, especially if they come to our house for activities. This activity should have left a deep impression on him. Every time he talks about it, he always looks forward to such activities. It takes a lot of thought and time to organize such an activity, but it is also worthwhile. Children can learn a lot from it, for example, they can realize that people with similar interests will be very happy together; You can bring like-minded people together through certain activities; You can change some things through your own actions; Happy things should be shared with others ... The activity flow is as follows: 1. Welcome: Aerial fireworks put down parachutes, spinning fish and paper balls on the balcony on the second floor, and observe whether their landing speed is the same. Principle: Air produces resistance to moving objects. 2. Group match: The straw game is divided into two groups, each with a straw, a bucket of water and an empty basin. Don't touch the bucket for two minutes. Let's see which group will take the water in the bucket to the basin to mobilize everyone to unite, and everyone will contribute their own strength to make the collective strength the greatest principle: the role of atmospheric pressure. Hold the straw in your hand, insert the straw into the water, then press one end of the straw to seal one end of the straw. 3. Siphon experiment Continue the previous experiment and ask: A hose, a bucket of water and an empty basin can't tilt the bucket. Can water flow from the bucket to the basin? After the demonstration, let everyone take turns to try whether they can siphon water independently. Reminder: Experiments are allowed to fail. If you fail, don't be discouraged, observe more and try again later. Principle: atmospheric pressure can be deepened: if the hose is long enough, can it siphon water when it is lifted very high? No, it can't exceed 10 meter. Atmospheric pressure is constant. 4. Compare who is the braggart: open the captured ping-pong funnel upward, put the ping-pong ball in the funnel, and then blow it into the small mouth to see who can blow the ping-pong ball out of the funnel. Principle: Bernoulli Law 5. Why doesn't water flow into the bottle? Insert the funnel into the bottle, seal the bottle with plasticine, and quickly pour a glass of water into the funnel to see if the water can stay in the bottle. Who can find a way to let water in without touching the bottle and funnel? Principle: Air is the first part of the experiment, occupying a certain space. For the previous experiment, if you are interested, you can invite other children to do it together or do it alone. Fly kites and play windmill games to increase the fun of sports, understand the energy of airflow and publicize the environmental awareness of wind power generation. 6. Wind at the corner: After the candle goes out, light the candle and start to block it with a narrow rectangular piece of paper, so that the child can blow it, but it will not go out. Then, put a round bottle in front of the candle and blow it out. Principle: Wind energy bypasses cylindrical objects. 7. Burning makes the cup stick to the washbasin. Prepare a washbasin, decorate it with water, then put the burning paper into the glass, and immediately remove the glass cover to the bottom of the washbasin. As a result, the cup sucked the washbasin. Principle: Burning paper makes the air in the glass expand when heated. When put into water, the fire goes out, the air immediately cools, the volume shrinks and the pressure in the cup decreases. The atmospheric pressure outside presses the washbasin and the cup together. 8. A newspaper that won't get wet put a ball of paper in a glass, then put the glass mouth down, put it in water, and then take out the water cup. As a result, the paper ball in the water cup was not wet. Principle: Air takes up space, but water can't get in. 9. Blow between two balls, will they leave? Hang two balls with a thin thread, leave a few millimeters, and then blow them in the middle with a straw. As a result, the two balls are very close. Principle: Bernoulli's law, the faster the speed, the less pressure. 10, the suction cup is really powerful. Principle: atmospheric pressure. After all the experiments are completed, everyone can choose to do experiments or read books freely. Parent communication. Remarks: Lalahao's comments are based on the children's reaction after we (adults and children) read them. Lalahao.com website lists all the books that children read, hoping to communicate with more parents and children.
