The course of scientific problems includes three modules: logical application, traceability and scientific inquiry. Committed to interdisciplinary learning, to achieve the learning goals of stimulating interest, cultivating ability and broadening horizons. Logic application starts from life, applies what you have learned and solves practical problems. For example, in the second grade experience class "Travel Planner" in autumn, every child becomes a travel planner, applying the knowledge of different disciplines to plan a two-day trip to Guangzhou. The class is equipped with travel planning cards, stickers, Guangzhou information newspaper and other teaching AIDS to make children feel more immersed, ceremonial and substitutive. Tracing back to the source-the direction of scientific spirit. A person's broad vision means a broad life, and the vision of walking determines the realm of seeing the world. On top of mathematics, there is an encyclopedia. The tracing module will lead children to explore through three themes: civilization exploration, non-legacy projects and the history of children's science. The direction of practice and innovation. Starting from nature, we can help improve children's scientific spirit by exploring natural laws and scientific practice. The first-year winter vacation "Inverted World" will learn the principle of pinhole imaging; The second-year winter vacation "Rushing into the sky" will explore the dynamic principle of air rockets; The third grade winter vacation "Trembling Earth" will learn the common types and principles of earthquakes; In the fourth grade winter vacation, I learned to make a simple flying machine in the space program. In the classroom, lead children to learn how to make guesses-find key arguments-verify scientific theorems-solve practical problems and provide support for children to improve their scientific literacy.
