DynamiQueST 2020

DynamiQueST 2020

DynamiQueST is a showcase of the power of simulations and creative student projects that utilize critical thinking skills to analyze complex dynamic systems.

In 2020, students will participate in a large scale climate change simulation as well as present their own work. This combination fosters an energetic learning environment as students learn the global power of system dynamics as well as experiencing what challenges their peers are tackling.

Model Mysteries:Energy Drink Mania

Energy Drinks Image

A MicroLesson adapted from Model Mysteries

by Anne LaVigne and Lees Stuntz

Energy drinks can be a quick way for people to increase alertness and energy in the short term, e.g., to study for a test or to complete a long, endurance drive. Caffeine in these drinks can also stay in the body for longer than you might think. Explore how different choices affect caffeine levels in the body over a 24 hour period!

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!
