Field Journal: Rocks
This online activity is part of the museum's Online Field Journal Web site, where young children can explore the wonders of nature with the help of an adult. The challenge here is to take a closer look at three rocks: Gowganda Tillite, Loraine Quartzite, and Gowganda Glacial Conglomerate. On the opening page, there are side-by-side photos of the three rocks; students are asked to describe each rock. Clicking a rock's photo takes students to a magnified view of the rock that also asks students tw

Soil Characterization Protocol
The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples are collected and prepared for additional laboratory analysis.
