Module 3 Lesson 3 - Adding a Predator

In this lesson, students will modify the Rabbits and Grass model by adding a predator, a Mountain Lion, to answer a new question: “Does adding a top predator increase or decrease the stability of an ecosystem?” In the second activity, students will design and run experiments to see if adding a predator has an impact on the ecosystem. This activity will reinforce the concepts of energy flow through ecosystems and the often unexpected results of interactions in complex adaptive systems.

What's Represented?

These exercises ask the learner to identify abstractions in the computer model as compared to a diagram or image of a natural phenomenon.

Project GUTS teacher & facilitator guides

These guides are aimed at helping teachers or workshop facilitators help their students or participants be independent learners while working with computer models. They are a work in progress - final versions will be uploaded soon. Please feel free to point out any corrections or additions in a discussion thread -- Thanks!

Papercatchers

Papercatchers is a participatory simulation in which students learn about population growth and limits to growth. Students play the role of members of a growing population, follow simple rules governing survival and reproduction, and collect and graph data.

Progress Monitors for CS in Science Modules (coding activities)

Progress Monitors are meant to be guides for students, giving goals for the model but not providing specific coding instructions.

Sample rubric for ecosystem module

This rubric was previously posted on the Code.org site and many teachers have found it to be helpful. You can save a copy and modify as fits your curriculum.

Computational Thinking for Youth in Action (2011)

This is an early paper of Computational Thinking that has a lot of traction. It's where we first describe the Use-Modify-Create trajectory.

Module 3 Lesson 2 - Rabbits and Grass Model

In this lesson, students will participate in two activities that USE the Rabbits and Grass model. The first activity is a look under the hood at the model to understand what was included and left out of the model (abstraction). In
the second activity, students will learn to design and conduct systematic experiments using the model as an experimental test bed. They will instrument their model to collect data, then analyze data and report out on
their findings.

Module 3 Lesson 1 - Ecosystems as Complex Adaptive systems

In this lesson, students will be introduced to ecosystems concepts through an activity called "Papercatchers", a participatory simulation in which students play the part of agents in a simulation. After playing the “game” that illustrates population dynamics and carrying capacity, students will view a computer model of a simple ecosystem. Through the model, students will review concepts of population growth, producers and consumers, and the movement of energy through an ecosystem.
