Splash! A New Way to Play

Create animated models of ecosystems? Predator and Prey dynamics? No problem with Splash! Think what fun kids will have using this new visual software to learn and integrate the powerful concepts of systems thinking to use as they think critically about the world.

Over the years we have found that the gap between the kinesthetic and pencil and paper tools (games, behavior-over-time graphs, causal loop diagrams and connection circles) and stock/flow mapping and modeling has been hard to cross for many students and teachers. We think Splash! will help bridge the gap.

Model Mysteries

Model Mysteries Book Cover

An Exploration of Vampires, Zombies, and Other Fantastic Scenarios to Make the World a Better Place

by Anne LaVigne and Lees Stuntz

If you’re interested in thinking about how to solve mysteries and like the idea of creating computer models and applying them to real-world problems, this book is for you. You can use it independently as a student, work with a group of students, or if you’re a teacher, share it with interested students to complete a guided or independent study.


Learn more, get the book, and some extensions (including some models with Stella Online!) at the Model Mysteries page.

Bumbles and Woofs: Population Modeling
by Rachel Henry

This lesson delineates a progression from a simple population model to a predator-prey model with an understandable and explicit sequence. Henry used Vensim simulation software for the class, but the lesson could easily be modified for other simulation software such as Stella or Splash!
