Students will see maps of Lake Superior and the St. Louis River to compare the sizes. Students will then each draw a portion of either the St. Louis River or a river near their school that flows into the St. Louis River or Lake Superior. They will make connections that every part of the river can impact the health of the rest of the river and of Lake Superior.
The emphasis on reading and understanding informational texts in classrooms mirrors our efforts in science at the Lake Superior NERR. These readings are based on real scientific efforts in the Lake Superior Watershed, and include questions to check for understanding. This reading on vernal pools is great for springtime and is derived from an article in the Duluth News Tribune, April 2016.
This is a one-pager, student sheet with quality images of cedar, balsam fir, red pine, spruce, and white pine needles for field identification and extension activities.

Regardless, GO OUTSIDE with your students and collect some samples of these trees for your classroom. Tell the Ojibwe oral story that explains this phenomenon.
