Students observe two objects in the outdoors (e.g. flowers, trees, rocks) and sketch them side by side, noting differences and similarities. Comparing two similar subjects makes their unique details stand out. Comparison is a basic tool used in scientific investigations to reveal patterns or collect data. When students make comparisons in nature, they will generate numerous relevant observations. This baseline of observations can support students to start thinking about how different structures work or how varied conditions might have affected the subjects they observed. Students can continue to use comparison as a tool in their journals.
