Status of Junior High School Chemistry Home Experiment with Preparation of Big Crystals as Example

以广州市花都区秀全外国语学校“大晶体制作”活动为例，调查学生开展家庭实验的现状，分析学生未能参加活动的原因，评估晶体制作活动对环境的友好性，并从基本概念、实验技能和情感态度3个维度，调查家庭实验活动对学生的作用强弱，论证了调查的可信性。提出了以环保为前提，以学生知、情、意、行的提升为目标，系统地组织学生开展家庭实验活动的基本策略。

Taking the activity of ＂making big crystals＂ in Xiuquan Foreign Language School of Huadu District for example, this paper investigated the status of students carrying out experi- ments at home, analyzed the reasons that students failed to participate in activities, assessed the environmental friendliness of this activity, and investigated the effect of home experiment activi- ties on students from three dimensions： the basic concept, experimental skills and emotional atti- tude.
