Teacher: "Look, children, what's the weather like?"
(1) Why does it thunder and lightning?
Teacher profile: Thunderstorms often occur in summer. Because the air rises rapidly in summer, there is a lot of electricity in the clouds. "Teaching case comes from: Teacher Qu's lesson plan network" When clouds collide, lightning will happen.
(2) Think about it: Do you see lightning or hear thunder first?
The teacher summed up: first see lightning, then hear thunder. Tell children that because light travels faster than sound, they first see lightning and then hear thunder.
3. Guide children to read children's books and discuss with teachers and students: methods of self-protection during thunderstorms.
Look at the picture and say: It rained and thundered. What did the children in the picture do? Is it safe to do so?
(1), children turn off TV at home in thunderstorm weather, right? Why?
During a thunderstorm, it is best not to use any electrical appliances to cut off the power supply at home. Because after the wire is struck by lightning, it is easy to conduct strong current to electrical appliances, and the use of television, computers and other electrical appliances will explode or burn, causing danger.
(2) Where can't we take shelter from the rain in a thunderstorm? Why?
In thunderstorm weather, don't stay in an open place, let alone play with the stagnant water on the ground, don't take shelter from the rain under a big tree, and don't walk around high-voltage lines. Because water, trees and iron can conduct electricity. )
(3) What harm will lightning bring to human beings?
Lightning can hit people or animals and cause fires. Therefore, people now install lightning rods on tall buildings so that lightning will not hit them. )
Activity reflection:
Children are familiar with thunderstorm days, but they don't know the process of lightning formation. When listening to the teacher's explanation, the children listened carefully. I focused on the formation of raindrops, and the children soon understood.
In the aspect of self-protection, we adopted the mode of scene performance to further increase children's self-protection experience. Targets 1 and 2 work well.
