This kit was designed to offer a complete unit for teachers, introducing students to important chemical tests for soil quality and fertility, and relating these measurements to the principles of plant metabolism.
Experiences anywhere
The teacher's guide provides detailed information for lessons/activities concerning soil quality, which can be adapted to suit various grade levels.
These lessons/activities allow students to explore three macronutrients and three parameters that impact soil quality, conducting tests with Hanna test kits and meters.
The tests contain step-by-step instructions for use in classrooms as well as in the field. All necessary materials are conveniently kept in the backpack, reducing the possibility of losing an item.
Easy to carry, this backpack is ideal for taking measurements directly in the field.
