Investigative Case - "Home, Home on the River"

Developed for Lifelines Online by Sara Simmers of Bismarck State College, Bismarck, ND. (http://bioquest.org/lifelines/index.html)

This activity was selected for the On the Cutting Edge Reviewed Teaching Collection

This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the process are

  • Scientific Accuracy
  • Alignment of Learning Goals, Activities, and Assessments
  • Pedagogic Effectiveness
  • Robustness (usability and dependability of all components)
  • Completeness of the ActivitySheet web page

This material is replicated on a number of sites as part of the SERC Pedagogic Service Project


Students will examine the complex issues that result from human use of ecologically sensitive areas. The students will investigate these issues from the point of view of their major/career path.

Learning Goals

Context for Use

This case is appropriate for use in a college level non-majors Biology Laboratory, especially of freshmen or non-traditional students. It is designed to include field work if weather permits. It is a mixture of independent and group work.

Considering Class Size - Different types of objectives can be accomplished by implementing case-based learning in different sized classes.

How Do Investigative Cases Fit into Courses?- What issues need to be taken into account before introducing cases to your class?

Teaching Materials


Ben and Tammy chuckled and reminisced over a cup of coffee at Barnes and Noble one Friday afternoon. It had been a few years since they had seen each other. Ben was studying to be an architect at the University of Minnesota, and Tammy was just starting graduate school in Botany at Colorado State. Now, they were both back home for a week before their summer jobs began elsewhere.

"Hey, I've got a great idea!" exclaimed Ben, "Let's go find that spot where we used to camp for weeks down by the Missouri!"

"Yeah," agreed Tammy, "That place was the best! Great fishing, too. And now with my all-knowledgeable degree in Botany, I'll be sure to not get caught up in the poison ivy."

The two chums drove to the park's edge in which they used to spend hours exploring, and found the faint trail that led to their recreational haven. However, much to their surprise, when they pushed their way through the underbrush of the cottonwoods, they were faced with a 2-story home that covered at least 3500 square feet, complete with columns around the front door and landscaping right up to the river's edge.

"Gee, Tam, this isn't quite how I remembered it," Ben sighed. "I guess they decided to upscale the camping facilities around here."

"You're so clever Ben," Tammy said sarcastically. "So much for your great idea. You know, isn't this supposed to be a publicly accessible park, and a conserved one at that? Look at the lots cleared for even more homes. Don't people realize that their manicured lawns and ornamental plants can affect the native plant species habitats?"

"It is disappointing, but look on the bright side, Tam, at least they used a simple cottage design for their dream home. Though the columns are tacky, I must admit. Hey, they kept a cottonwood in their backyard," Ben offered.

"Seriously, Ben," Tammy retorted. "Development can have many effects on biodiversity and the quality of the natural environment."

"True, but you have to consider other perspectives," replied Ben. "This scenery and the view are important in architectural design. I'm not so sure about the building codes so close to the water's edge, but I doubt they're doing that much damage. This area is important to a lot of people in our area. Not everyone's a biologist."
