Avi Hofstein developed Inquiry-type Experiments at the Weizmann Institute of Science, Israel using a two-phase method. The first phase, Pre-inquiry, teaches students to make observations, while the second Inquiry Phase requires students to ask relevant questions, formulate hypotheses, and conduct planned experiments to test their hypotheses. At Raffles Institution, we work with high-ability boys (ages 15-16) and run a highly compacted curriculum. To better meet the needs of these students and demands of this curriculum, we adapted Hofstein’s method for teaching the concepts of rate of reaction and the reactivity of metals. We will share how we modified Hofstein’s method and the activities we implemented, as well as the reflections of teachers and feedback from students.
