本文就小学电流实验盒的实验要求,实验步骤与方法,仪器盒的主要附件,提出初步设想.供研制或自制教具时参考.一、实验要求1.电路中基本元件的名称,结构和用途;2.简单的串联与并联电路;3.导体、半导体和绝缘体;4.电磁铁的结构、性质和用途;5.电能的初步应用.电流实验盒包括了小学自然课本第六册中电流、导体、半导体、绝缘体、电磁铁、电能等四节课的四次实验内容.因此,要充分考虑这四节课实验在知识上的内在联系,合理没计,力求用较少的附件,完成教材中主要实验.电器元件要结构简单、直观,电路连结件,夹紧件要接触可靠,便于儿重操
In this paper, the experimental requirements, experimental procedures and methods of the primary current experiment box, and the main accessories of the instrument box are put forward. For reference when developing or self-manufacturing teaching aids. I. Experimental requirements 1. Name, structure and purpose of the basic components in the circuit; 2. Simple series and parallel circuits; 3. Conductors, semiconductors, and insulators; 4. Structure, properties, and uses of electromagnets; 5. Preliminary application of electric energy. Current experiment boxes include elementary books in the elementary school. , semiconductors, insulators, electromagnets, electrical energy and other four courses of the four experimental content. Therefore, we must fully consider the four experiments in the knowledge of the internal link, reasonable did not count, and strive to complete the teaching materials with fewer attachments The main experiment. The electrical components should be simple and intuitive, and the circuit components and clamping components must be contacted reliably to facilitate re-operation.
