Grades 9–12. This refill kit provides the consumable materials for the Inquiries in Science®: Saving Soils Kit (item #251402).



In stock and available to ship.
  • Demonstrate soil characteristics with easy-to-perform activities
  • Sample runoff water to quantitatively evaluate erosion control
  • Relate soil properties to sustainable agricultural practices
A Carolina Exclusive! Grades 9-12. Students explore the formation of soil and its physical properties when it reacts with water. Performing 3 different activities over 2 lab periods, students investigate weathering of rocks, particle size composition of local soils, and the rate of permeability of different soil samples. They then apply their knowledge to construct a model of a slope that has been cleared for farming and design a plan that modifies the slope to reduce erosion. Kit Refill replenishes consumed materials.

Note: Order an extra kit refill for each additional class section. For example, to teach the kit in 3 environmental science sections on the same day, purchase 1 kit, 2 kit refills, and 2 multi class equipment sets. Part of the Inquiries in Science® series.

Inquiries in Science Series

Inquiries in Science® Series Kits

Inquiries in Science® is our exclusive series of hands-on kits specifically designed to help high school students understand abstract, hard-to-grasp science concepts. The series tracks well with most textbooks, and kit topics reflect state science standards and extensive educator input. Since Inquiries in Science® is modular, you can use the kits individually, as a strand, or as a series to teach biology, chemistry, and environmental science.

Improve Student Achievement

Field-tested in classrooms nationwide, Inquiries in Science® employs guided inquiry based on the 5E learning cycle of engage, explore, explain, extend, and evaluate. This inquiry-based approach also promotes STEM (science, technology, engineering, and math) practices. It enables students to:

  • Consider a real-world question or problem
  • Plan and conduct an investigation and gather data
  • Understand the science concept by analyzing data and communicating findings
  • Apply their findings to the original real-world question or problem and master the science concept

Inquiries in Science® helps students build critical-thinking and problem-solving skills, and encourages creativity, collaboration, and teamwork. It creates an environment in which you and your students work together as active learners.

Disciplines and topics addressed by the kits were organized and selected based on data from numerous sources, including the National Research Council's National Science Education Standards, AAAS's Project 2061 Science Benchmarks, NAEP's Science Framework, and state science education standards from across the US. In addition, the Inquiries in Science® content and activities reflect the science practices and engineering practices, core ideas, and crosscutting concepts outlined by the National Research Council's A Framework for K–12 Science Education (2011) and the Next Generation Science Standards (2013).
