Abstract: In this article we present simple and feasible idea to introduce electrolysis experiments using accessible materials in the classroom. We use plastic syringes and pipettes to build different shapes of Hoffman apparatus for electrolysis. This activity was introduced to a group of 20 teachers from the Arab sector in Israel to examine their impressions about the activity and investigate the feasibility of implementing the activity in their classrooms.

Key words: electrolysis workshop, professional development of teachers, case study, accessible materials, plastic apparatus
