CASES Online is a collection of inquiry-based lessons to engage K-12 and undergraduate students in exploring the science behind real-world problems. Through CASES, you can transform your students into motivated investigators, self-directed and life-long learners, critical thinkers and keen problem solvers. Our cases are grounded in Problem-Based Learning (PBL), Investigative Case-Based Learning (ICBL), and related student-centered pedagogies. [more]

We were featured in HHMI's Cool Science.

Materials for over 300 cases are now posted and we are continually working to publish more. We are working on updating our email notification tool in order to notify users of updates to the site. View an RSS feed of our latest cases.

Search tips: Searching by Keyword alone is best (and is not case-sensitive) since many cases can work across disciplines and grade levels. Try a more general search by leaving the subject and grade, and/or keyword blank. You may also search by author's last name. Results will display by grade level.
