Exercise
Form 4: Practical Conduction Experiments
In this hands-on exercise, students will explore the principles of thermal conduction by conducting experiments that involve different materials, measuring temperature changes, and analyzing their findings to understand how heat transfers through solids. Get ready to ignite your curiosity and discover the science behind conductive heat!
