In this activity, students will examine varying dynamics in seed dispersal by wind, bird, and monkey, interpreting data and making predictions.

In this activity, students will use data from natural parks to examine trophic cascades.

These slides have an overview of what was discussed in the Invitation to Modeling Workshop, with links to resources embedded in presentation and listed below.

Resource-limited growth

Most students have seen an exponential model for population growth and know that it predicts unlimited growth. Better models, such as the logistic growth model, should incorporate assumptions to account for limitation of resources. In this activity, participants collect data from a physical simulation of resource-limited growth, prepare a variety of graphs to visualize the data, construct a verbal model based on their observations and the graphs, and (for those who want to go this far) construct a symbolic model from the verbal model.
