生物对环境的适应和影响教学设计 教学课题 生物对环境的适应和影响 授课班级 初一1—3班 教学用时 1课时 备课时间 第四周 教材分析 本节课选自鲁科版初中生物学年级册第单元第章第节。生物圈中的各种生物，都离不开环境对他们的影响。那么，生物又是怎样适应和影响环境的呢？教材是按照“生物对环境的适应”和“生物对环境的影响”两部分编写的。第一部分出示了几幅图片，试图使学生通过观察、分析图片，理解生物的生活都是与环境相适应的；第二部分是让学生通过“植物对空气湿度的影响”的探究活动，理解生物对环境是有影响的。最后总结：生物与环境的相互作用造就了今天欣欣向荣的生物实践证明，在教学中，充分利用新教材的优势，创设一个民主、和谐的课堂氛围，引导学生开展探究性学习，利用多媒体的现代教育手段支撑整个教学过程，使学生在一个生动、有趣、多姿多彩的生物课堂中，愉快地“享受”学习。 I signed with the Bank of the qilu Bank loan contract (contract) conventions, and I use scheme, I would request the loans (in words) until I opened personal settlement account with your Bank (account), uses loan for 。 Loan operation, business unit name: account number: loan funds from these personal settlement account into the account of a payment.
