This article describes activities in which students sample, investigate, classify, and compare characteristics (i.e., texture, color, density, porosity) of local soils, evaluating whether the soils are healthy or at risk. Students investigate correlations between geology and geography, predict which soil types may go extinct in their state, and…

Graphs represent complex information. They show relationships and help students see patterns and compare data. Students often do not appreciate the illuminating power of graphs, interpreting them literally rather than as symbolic representations (Leinhardt, Zaslavsky, and Stein 1990).

The teachers analyzed and reflected on their transcripts using a coding manual and a comparison and reflection guide. The coding…

Presents a hands-on activity in which students try to identify 15 unknowns using only their sense of touch. This method reinforces the science process skills of observing, collecting and recording data, and analyzing data tables while requiring few reading skills. (MDH)
