Third, we must consolidate our achievements. For more public, some party members who focus on the outstanding issues, combining concentrated知识与能力：初步熟悉化学实验基本技能训练。过程与方法：通过动手演示，初步熟悉化学实验基本技能训练。教学目标情感、态度与价值观：培养学生严肃认真、实事求是的科学态度，养成勤于思考、勇于实践的科学态度。初步培养学生的实验技能，养成良好的实验习惯和观察判断能力，提高他们分析问题的能力。教学重点化学实验基本技能训练教学难点课前准备化学实验基本技能训练实验器材引入新课：通过上节课的学习，我们已经知道了化学实验的重要性。二、化学实验基本技能训练 1、固体药品的取用方法（1）固体药品通常保存在广口瓶里，往试管装入固体粉末时，取用固体药品一般用药匙。有些块状的药品（如石灰石等）可用镊子夹取。用过的药匙或镊子要立刻用干净的纸擦拭干净，以备下次使用。（2）往试管里装入固体粉末时，为避免药品沾在管口和管壁上，可先使试管倾斜，把盛有药品的药匙（或用小纸条折叠成的纸槽）小心地送至试管底部,然后使试管直立起来。（3）把密度较大的块状药品或金属颗粒放入玻璃容器时，应该先把容器横放，把药品或金属颗粒放入容器口以后，再把容器慢慢地竖立起来，使药品或金属颗粒缓缓地滑到容器的底部，以免打破容器。 2、液体药品的取用（1）液体药品通常盛放在细口瓶里。取用液体药品时应注意： a.细口瓶的塞子要倒放在桌子上； b.倾倒液体时，瓶口要紧挨着试管口，应该缓慢地倒； c.拿细口瓶倒液时，贴标签的一面要朝向手心处； d. 倒完液体后，要立即盖紧瓶塞，并把瓶子放回原处。（2）取用一定量的液体药品，常用量筒量出体积。量液时，量筒必须放平。视线要与量筒内液体的凹液面的最低处保持水平，再读出液体的体积。（3）取用少量液体时还可用滴管。取液后的滴管，应保持橡胶胶帽在上，不要平放或倒置，防止液体倒流，沾污试剂或腐蚀橡胶胶帽；不要把滴管放在实验台或其他地方，以免沾污滴管。用过的滴管要立即用清水冲洗干净（滴瓶上的滴管不要用水冲洗），以备再用。严禁用未经清洗的滴管再吸取别的试剂。 3、固体试剂的称量(托盘天平的使用) ⑴托盘天平只能用于粗略的称量，能精确到0.1g。 ⑵称量前先把天平放在水平桌面上，把游码放在标尺的零刻度处，检查天平ectification and strengthening the management of daily education, the spirit of reform short of the complete system, pay close attention to system implementation, really make the party organization and party member education and strict management, solid. Finally, the \d, be sure to promote efficiency. \on, not on education educational, not working with the Centre two, must stick around the Center, serving the overall situation, coordinate, truly result-oriented and promote efficiency. Current and future a period, to tightly around coordination advance \ng full built society this a central and work overall, put carried out learning education as promoted work of important opportunities and powerful power, guide General members cadres insisted development first priority, active adapted economic development new normal, consciously practice line five big development concept, effective grasp supply side structural reform, to guarantees and improved livelihood, construction more high ecological vitality happiness of city.
