Simulations
The Arcytech link provides a simple predator-prey simulation with squirrels, hawks, and habitat. The simulation worked well as a review activity with Grade 10 pre-IB classes.
The Explore Learning site with simulations, or gizmos, for teachers can provide a year long set of simulations or you may use the trial period to complete a single activity. Several teachers at my school have used a variety of the simulations and found them to be useful.
The site biointeractive offers a list of resources some of which are simulations. These sites have not been tested.
