Description
The HI3896BP is a classroom in a backpack Hanna chemical test kits and pocket testers included in this Backpack Lab provide teachers with a valuable tool in helping students address important issues related to soil quality and modern agriculture practices. Real-world examples help students understand the relevance of macronutrients and other parameters in everyday life. Teachers are able to introduce students to important chemical tests for evaluating soil quality and fertility, and relate these measurements to the principles of plant metabolism.
