Grantsburg High School Research Biology, Summer 2005 St. Croix River of Life by Kerissa Nelson - GHS
The boring answer: • The state demands it! State Science Standards require that students engage in inquiry based activities.
The selfish answer: • I like it! Anything I can do to get outside as a teacher is good!
Be Honest! • A day on the St. Croix SCUBA diving and canoeing or…. • a day in a white walled building with periodic bells, raging hormones, and continual complaining about homework.
The Real Reasons • Students learn best by doing.
The Real Reasons • Students learn best by doing. • You don’t learn much biology from a text book.
For example.. • A text book says that freshwater mussels use fish to reproduce.
A picture can show how they attract fish. (Just how many fish are in this picture?)
The Real Reasons • Students learn best by doing. • You don’t learn much biology from a text book. • Rivers are more than fish and water – they are ecosystems and this is a complex concept for students to understand.

The #1 Reason • Ownership – It’s not just class, it’s not just a project – It becomes their class and their project.
The #1 Reason • Ownership – It’s not just class, it’s not just a project – It becomes their class and their project. • Ultimately, it becomes their river.
Summer of 2005 • A Longitudinal Survey of Dragonfly Communities on the St. Croix River and its Wisconsin Tributaries.
Summer of 2005 • A Longitudinal Survey of Dragonfly Communities on the St. Croix River and its Wisconsin Tributaries. • A Quantitative Survey of the Unionid Mussels Below Four Dams on Three Wisconsin Tributaries of the St. Croix River
Dragonfly Study Objectives: • Increase Public Awareness about Endangered Dragonflies of the St. Croix River
Dragonfly Study Objectives: • Increase Public Awareness about Endangered Dragonflies of the St. Croix River • Give Students an Understanding of Dragonfly Life Cycles and Habitat Associations
Dragonfly Study Objectives: • Increase Public Awareness about Endangered Dragonflies of the St. Croix River • Give Students an Understanding of Dragonfly Life Cycles and Habitat Associations • Gain an understanding of species distribution and community ordination throughout the St. Croix River
We sampled 100 ft. segments of river bank for dragonfly exoskeletons at 70 sites on the St. Croix River 1time/week.
After we had sorted for four weeks – things got a little crazy
We had identified and counted over 11,000 exoskeletons! • This included 43 species
We had identified and counted over 11,000 exoskeletons! • This included 43 species • A new Minnesota state record the Cyrano Darner (Nasiaeshna pentacantha)
We had identified and counted over 11,000 exoskeletons! • This included 43 species • A new Minnesota state record the Cyrano Darner (Nasiaeshna pentacantha) • A few more mysteries that we continue to work on. >!< >!<
After all data was recorded and organized, we could produce species distributions
