Product Description
This unit on soil science contains a 16-page student section that covers soil components (clay, sand, and silt, loam, humus, soil texture (including the texture triangle), soil horizons, and movement of water through soil. Five discovery labs are embedded within the student hand-out: (1) soil make-up (visual inspection), (2) describing soil (by feel and settling), (3) the ribbon test for clay content (including an adapted method for small hands), (4) separating sand, silt, and clay by sedimentation, and (5) building a soil column (in a plastic cup). In addition, directions are provided for a discovery lab in which the teacher demonstrates water flow through the soil column. Extensive teacher notes, including lists of materials and set-up directions, are provided for the discovery labs. The discovery labs are aimed at learning by doing with the text supplying information that directly supports the labs; the intent is for this unit to be a student-focused, hands-on experience. Additionally, teacher notes provide songs, using music to reinforce concepts; a simple song is based on “Old MacDonald Had a Farm.” A more extensive song is based on “Home on the Range,” with geographically inspired verses; melody-only sheet music is provided. Student assessment activities include a 34-question test with matching, multiple choice, and completion. The package has three basic worksheets: (1) using the soil texture triangle, (2) comprehending soil horizons, and (3) applying knowledge. It has three enrichment activities: (1) an internet activity that extends into botany and ecology, (2) a question worksheet on soil hydrology, and (3) a question worksheet on the Teton Dam failure based on an online video clip at History.com. A complete answer key is provided for all student assessments. Even though specific grades have been targeted, the unit is designed to be adaptable for use down to grade 2, especially the discovery labs.
