Activity purpose
1, discover the phenomenon of rotation in life and understand the application of rotation in life.
2. Explore ways to make objects rotate and experience the fun of scientific exploration.
3. During the activity, let the children experience the joy of success.
4. Develop children's observation and imagination.
Activities to be prepared
1, toy car.
2. Children's operating materials: windmills, gyroscopes, jingles, ropes, CDs, spoons, chopsticks, balls, plastic toys and other common items in life (the number is more than the total number of children).
3. Courseware; Pictures of various rotating objects, such as washing machines, fans, helicopters, etc.
Activity process
1, showing toy cars arouses children's interest: What do you think the teacher brought, little friend? Do you know which part of the car will turn? Lead to the theme.
2. Question: What have you found that can change our lives? How to turn? Let children imitate the rotation of objects with their bodies.
Show the objects that can be rotated in life with courseware, and let the children talk about the uses of these rotatable things. For example, the rotation of the fan can make people feel cool, the rotation of the washing machine can wash clothes, the rotation of the wheels can make the car run, and the rotation of the clock can let people know the time.
Conclusion: Rotation plays a great role and can bring a lot of convenience to our life.
3. The child tries to explore for the first time: let the object that is easy to rotate rotate.
(1) Please observe the materials provided by the teacher, such as windmills, hula hoops, mineral water bottles, gyroscopes, ropes, etc., and guess what can turn and what can't.
(2) Guide each child to choose one or two materials and try to make some turning points.
(3) Please tell your child how to make the material rotate in complete language.
4. Second trial operation: try to make materials that can't be rotated.
Question: Do you think any of the materials just now can't be rotated? Is there any way to make it spin? Encourage young children to find ways to make seemingly immovable objects rotate. Such as: stir the water in the bowl with a spoon, and the water will turn; Shake the chopsticks in the bottle, the bottle can rotate and so on.
Conclusion: As long as we are willing to use our brains, we can also find ways to turn things that seem to be unable to turn around.
5. Watch the courseware to further understand the wide application of rotation in life.
Watch pictures of machine rotation, wind turbine, helicopter propeller, merry-go-round, etc. Let the children observe and say: What is this rotation? Guess what it's for?
Summary: Rotation can be seen everywhere in our lives. People have invented many things by using the principle of rotation, which is really useful.
6.End: children, there are many toys that can rotate outside our activity room. Let's go and have a look!
7. Activity extension: The above materials can be put into the science area, so that children can constantly explore the rotation.
Teaching reflection:
The beginning of a scientific activity should come from children's existing experience, and the end of a scientific activity is not really the end. Let children have the possibility of further exploration and become the beginning of gaining experience. Children are the masters of learning, so our teachers should try their best to create various learning environments, so that children can see, listen, speak and think with their brains, explore wholeheartedly and actively, and give them free space to show. Let children gain knowledge and experience in games and happiness.
