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.

Instructor Manual with everything you need from background information and setting up the classroom to a shopping list for everyday items
Student Manual including test procedure, data sheets, and puzzles
Students work in groups and individually
Encourages critical thinking and active learning
Flipped learning: Students can read background material before the lesson and apply knowledge to analyze their own classroom data
Works on computer or tablet
Great for inclusion classrooms

The Insta-TEST^® Wide Range pH test strips are a convenient way to test water for pH. Range and sensitivity is 4, 5, 6, 7, 8, 9, 10.

Elementary Education Watershed Field Trip helps to explain the Watershed and provides guidelines on taking a field trip, conducting water quality tests, and data sheets for collection and interpretation of data.

Twelve-inch rim dip net is fitted with a heavy canvas bag approximately 6″ deep. Bag attached to metal frame with clamp rings. Bottom of bag is a mesh material of approximately 500 micron nylon. Canvas skirt extends three inches below bag bottom to protect mesh. Aluminum pole extends from 52″ to 84″. Replacement bags available.

This kit measures for acidity by using the phenolphthalein endpoint to determine hydrochloric, sulfuric, and phosphoric acids. Range/sensitivity is 1 drop = 0.1 or 1.0% (as the particular acid).

This kit tests for pH using the Octa-Slide 2 Comparator ranging from 7.2 – 8.6 pH.

The Nitty Gritty Soil Science kit is a great introduction to the basic concepts of soil science. Instructions for cool science experiments and Just for Fun activities, games, and internet connections are included.

Investigate healthy plant requirements for proper soil texture, ideal levels of soil pH, and nutrients. Learn to properly care for plants and perform pH, nitrate, phosphate and potassium soil tests using non-hazardous TesTab methods. Reagents for ten tests for each test factor are included. Make friends with earthworms and discover the importance of composting! Recommended for green- and dirty-thumbs ages 8 and up.

The Insta-TEST^® Nitrate / Nitrite test strips are a convenient way to quickly test water for Nitrates. Ranges and Sensitivity: Nitrate – 0, 5, 10, 25, 50 (NO₃-N), Nitrite – 0, 0.5, 1, 5, 10 (NO₂-N).

Ideal for examining water quality in known or suspected polluted aquatic environments.
