3、生参与积极性高，想说，敢说，思路开阔。四、体现了科学课的本质。本课体现了科学学科的本质科学课不是教知识，而是教孩子科学研究的方法。无论是指导思想、课的设计都充分体现了新的理念，科学地想问题，指导科学地做，有计划地做，能动地搜集资料等。结束语！祝大家学到有用的知识，提升自己的能力，实现自己的梦想，踏踏实实干好每一件事，为美好的明天而努力！16fnt15g5d8o6zlgi3l0shk.wfhqo0utuu5fu5v3q7xjyqwnlf,4nir01v0cy4myeevnurf8t9l0goa0rcu9itmnj02rr7yfxj2j5zu7r2da4xc9k.pk4eibp9ktm7ejhdg
