The Topsoil Tour is an exciting classroom investigation into the physical and chemical properties of soil. Each student on the Topsoil Tour completes seven units while conducting his/her own soil tests for soil texture, pH, nitrogen, phosphorus and potassium using simple TesTabs® reagent tablets. Incorporates math and science activities.
Activities can be modified to fit specific curriculum needs or learning opportunities. Data sheets and puzzles for each unit can be printed or filled electronically by students using a computer or tablet. Includes Instructor Manual, Student Manual with data sheets and puzzles, classroom color chart, and reagents and test tubes for 50 students.
