Basic 8 Science Term 1 Week 3 Lesson Plan

Revise with learners on the previous lesson.

Groups pour the Sand-and-water mixture through the Filter funnel with filter paper and identify the residue and filtrate. The teacher places the Salt-water evaporation dish in a safe warm location or uses a teacher-controlled low heat source and learners observe solvent loss and salt recovery. Learners draw both setups, name each separation method and explain which physical property makes it work. Hot apparatus is handled only by the teacher.

Use peer discussion and effective questioning to find out from learners what they have learnt during the lesson.

Share learning indicators and introduce the lesson.

Learners identify the parts and flow path of the Simple distillation apparatus before heating begins. The teacher heats the Salt-water mixture while groups observe boiling, condensation and the liquid entering the Collecting beaker from a safe distance. Learners compare the collected water with the salt left behind and draw a labelled process diagram. Only the teacher handles the heat source, hot glassware and apparatus connections.

Take feedback from learners and summarize the lesson.

Groups first inspect the sealed Camphor-and-sand mixture without touching or smelling it directly. The teacher warms it in the Covered evaporating dish in a ventilated area while learners observe from a safe distance. Learners arrange and annotate the Printed sublimation-sequence chart to show camphor changing from solid to vapour and depositing separately from sand. Iodine is not used and only the teacher handles heated material.
