一、教具装置图(如图1所示)二、教具作用使用本教具可实验探索原始地球条件下有机小分子——氨基酸在原始地球上的形成过程,大致了解地球生命起源的简单过程,从而培养学生的探索精神。三、实验原理原始大气中的氨气、二氧化碳、甲烷、水蒸汽和少量氢气等无机小分子在闪电、紫外线、宇宙射线等作用 First, the aids device diagram (shown in Figure 1) Second, the role of teaching aids Use of the aids to experimentally explore the primitive Earth conditions small organic molecules - amino acids in the original Earth's formation process, a rough understanding of the origins of Earth's life simple process, which Cultivate students' exploration spirit. Third, the experimental principle The original atmosphere of ammonia, carbon dioxide, methane, water vapor and a small amount of hydrogen and other small inorganic molecules in the lightning, ultraviolet rays, cosmic rays and other effects
