Level A: Up and Down in the Wild: Predator and Prey This lesson allows students to explore the interactions of two animal populations (wolves and moose) within an ecosystem. One animal in the simulation is a predator. The other animal is its prey. Their populations rise and fall (oscillate) over time as they interact and impact one another.

Students use a simple simulation to explore "what if" questions relating to characters. They can change how characters behave to consider whether a story might have emerged differently. Note that students do not need to read the play, The Tragedy of Romeo and Juliet in order to explore the simulation.

Level B: Wild Things: Interacting Populations This lesson allows students to explore the interactions of two animal populations (predator and prey) within an ecosystem. Their populations can rise and fall (oscillate) over time as they interact and impact one another.

This simulation allows you to explore choices for scheduling time; you can schedule more activities or fewer activities. Activities include going to school, studying, working a part-time job, playing sports, being in a club, and taking care of a younger sibling.

All the other sims in the book can be done using the free Stella Model Editor.

The behavior over time of a population limited by density-dependent factors is called logistic growth. You will be simulating a model of logistic population growth. You'll be able to change factors that address how fast an animal population grows, how long individuals in the population live on average, and how much area the population has available. See if you can vary the shape of the logistic curve, or create something different.

Predator/Prey/Biomass Level B: Circles of Interaction: Predator, Prey and Plants This lesson explores predator (wolf), prey (moose), and food (plants) within an ecosystem. Students role-play being a wildlife manager who is doing "on the job" training. The manager controls hunting of prey populations and killing of predators. The default simulation behavior for prey, predators, and food is oscillation.

Predator/Prey/Biomass Level A: All Together Now: Predator, Prey and Plants This lesson allows students to explore the interactions of two animal populations (wolves and moose) and plants within an ecosystem. The populations and the plants rise and fall (oscillate) over time as they interact and impact one another.

Springs Everywhere: Exploring Spring-mass Dynamics - Level C What makes a spring, a spring? Springs are all around us, but rarely thought of or considered for what they are – oscillating systems.

This simulation is part of the oscillations series from the Creative Learning Exchange, http://www.clexchange.org/curriculum/complexsystems/oscillation/default.asp

This lesson explores how animal populations can grow and decline over time through use of a simulation. This very simple model allows students to impact the birth and death rates based on input for different animals. The simulation displays what happens to the different populations over time. Students can compare the resulting trends for different animals and consider why those trends occur. Students may also research additional animal data in order to create their own runs.

This model is the same as one demonstrated using Splash!, a new app that uses liquid physics to model systems

Part of the osillation series, this simulation explores populations with a carrying capacity (one that does not oscillate because it has just one stock).

Part of the oscillations series of simulations, this sim explores a what if scenario, had Romeo and Juliet not ended in tragedy.
