The document describes a laboratory activity where students collected disturbed and undisturbed soil samples to study soil properties and behavior. The activity involved digging at a mini-forest to obtain disturbed soil samples using tools like shovels and crowbars. Undisturbed samples were collected by inserting steel tubes carefully into the soil. Objectives were to observe differences between disturbed and undisturbed soils, and understand how soil properties impact temperature, pressure, and engineering applications. Proper sampling methods and tools were needed to gather representative samples for different tests.
