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.

Walk & Turn for StarLogo Nova

This is the CS in Science, Module 1, Activity 1 activity. Students participate in an activity acting as agents, then view a computer model, to introduce concepts of computer science and complex adaptive systems.

Dice and Data (see also CS in Science, Module 1)

Dice and data is a hands-on activity in which students learn about probability and how probability is used in modeling and simulation. Students first investigate single dice rolls and connect the results to randomness, then students investigate two die rolls and learn how the results of two-die rolls are used to mimic animal movement in a wiggle walk.

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.

CS in Science: Module 1 Additional Resources

Ready to implement? Here are some additional resources and links to other Teachers with GUTS pages to help you with CS in Science, Module 1 (Introduction to Computer Modeling and Simulation). Some of the resources refer specifically to StarLogo Nova 1.0 (teacher videos) and others to StarLogo Nova 2.0 (link to models gallery). Check the relevant page for CS in Science Module 1 for the version of StarLogo Nova you are using.

Computer Science Concepts Guide for CS in Science Modules

This summary of Computer Science concepts introduced in CS in Science Modules can be used with either StarLogo Nova 1.0 or StarLogo Nova 2.0. It lists and explains the various concepts, organized by when they are introduced in the CS in Science curriculum.

Debugging Challenges for StarLogo Nova

These challenges ask students to identify and correct common coding errors within StarLogo Nova programs. The first challenge is generic, all others relate to the content area module from CS in Science. Students like to solve the problems and fix the code, and learn about debugging skills while engaging further with content area modules. It is also a good review for instructions/facilitators before building code with students.

Coding Challenges

Coding Challenge are a series of short challenges that focus on improving coding skills using StarLogo Nova. Each set of challenges focuses on a specific concept: degrees & heading, x & y coordinates and randomness, conditions including absolute value and percent chance, adding color to the terrain and repeat loops, using the z coordinate, and other computer science concepts (logic blocks, data collection),.

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.

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.

Pair Programming video

This short video (2:51 minutes) features two middle school girls describing and practicing pair programming. It is a great introduction to this method of learning programming and creating models.

Complex Adaptive Systems Modeling Video

This short video (3:13 minutes) introduces complex adaptive systems and agent-based modeling concepts to middle-school students. It shows beautiful footage of birds flocking as an example of a complex adaptive system.

Alternate activities to introduce Project GUTS

Sometimes, teachers have a students who have already participated in Project GUTS introductory activities, and want to use something different, or want another activity to expand a lesson. Below are links to some alternate activities, both hands-on and on-line, for you to explore.

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.

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.
