Probing Questions

Article excerpt

On a brisk, overcast day a busload of budding scientists from Old Orchard Elementary and Monroe Middle schools in Columbus, Ohio, embarked on a field trip to Spruce Run Environmental Education Center. Spruce Run is located on 50 acres of land donated to Columbus Public Schools by Robert and Dorothy Patton in 1974. It is well suited for outdoor education, with a variety of geologic features including a succession plot, woodland, meadow, shale creek bed, flood plain, and ridge. A portable classroom equipped with electricity and running water serves as a shelter and area for indoor activities.

As the students emerged from the bus, the air was filled with excitement and anticipation. This was no ordinary field trip. These urban scientists were going to collect data with science probes that would help them find the answers to questions posed about the differences in the ecosystems of a stream, forest, and meadow. Which type of soil supports more plant life? Why do you think the habitats have different pH levels in the soil? Are there different temperature readings among the ecosystems? After being divided into groups, students were given worksheets (see "Soil Sample Worksheet" at right) and rotated through stations where they learned about the characteristics of ecosystems, soil pH, difference between air and ground temperatures, and how to use probes. Laptop computers were set up in the shelter house to manipulate the information. Prior to this scientific expedition, students were prepped with background information on habitats, pH, making predictions, and soil composition. Web sites provided valuable background information and contributed to the prior knowledge necessary for scientific inquiry.

ECOSYSTEMS

Biomes of the World

Basic concepts about biomes and ecosystems around the world are presented along with photographs and illustrations. You can find facts and definitions about deserts, forests, grasslands, streams, wetlands, and oceans. The site is easy to navigate and suitable for elementary and middle school students.
