This study investigates the impact of instructional methods based on a one-day informal science field experience comparing a teacher-centered methodology versus a student-centered (inquiry-based) methodology. The 5E learning cycle was selected as the framework for implementing the inquiry-based learning for the treatment groups as it provides the…

This column focuses on promoting learning through assessment. The formative assessment probe in this month's issue can be used as an initial elicitation before students are introduced to the formal concepts of weathering and erosion.

This paper reports on the results of several geotechnical engineering-related science activities conducted with elementary-school students. Activities presented include soil permeability, contact stress, soil stratigraphy, shallow and deep foundations, and erosion in rivers. The permeability activity employed the LEGO NXT platform for data…

This quasi-experimental study compared the effects of concept mapping and teacher generated questioning on students' organization and retention of science knowledge when used along with interactive informational read-alouds. Fifty-eight third grade students completed an eight-day unit regarding "soil formation." Students who participated…

Take plant lessons outdoors with this engaging and inquiry-based activity in which third-grade students learn how to apply soil conservation methods to growing plants. They also collect data and draw conclusions about the effectiveness of their method of soil conservation. An added benefit to this activity is that the third-grade students played…

Have you ever played in the dirt? Repotted a plant? Planted a garden? In each and every one of these activities, you touched something that is a valuable resource in our lives--dirt! This month's column has students investigating different aspects of something that is right beneath our feet but plays an important role in the daily lives of many…

In this article, the authors present hands-on activities and demonstrations using readily available materials that help students learn how to prevent soil erosion. With this series of active-learning exercises, the students will be able to practice scientific inquiry while learning about soil as a valuable resource. After demonstrations on the…
