Cambridge Year 8 Science: Conductors & Insulators | Conductivity Analysis

Cambridge Year 8 Science: Conductors & Insulators | Conductivity Analysis

Explore electrical conductivity with this hands-on Cambridge Year 8 Electricity & Magnetism investigation. Students investigate everyday materials, predict whether they will conduct electricity, carry out a fair test, analyse their evidence, and connect their findings to electrical safety and real-world applications.
Designed for Grades 6–8 and approximately 1–2 × 45–60 minute classes.
