Teachers can use Garry's Mod (GMod) as a demonstration tool for physics experiments that are otherwise impractical for class. For example, a teacher could create a rocket, giant catapult, or two objects that push against each other with more force than can be safely (or possibly) generated at school.
Teachers can also help students model experimental designs and solutions to physics and 3-D geometry problems, and students who want to share their work (with the appropriate permissions) can create and post expository pieces explaining their creations on DIY sites such as Instructables. Teachers and students can also use GMod to create explorable 3-D maps and models that connect to class content.Continue reading Show less
GMod is a physics sandbox stuffed with art and models from Valve software's popular games, including Half-Life 2 and Counter-Strike. With a large library of generic objects, recognizable props from Valve's games, and pre-built devices such as thrusters and wheels, users can build and share nearly anything they can imagine.
Every object's physical properties can be modified, letting players tweak things such as lighting or the amount of force and torque an object can create or withstand. With GMod, students can model solutions to physics problems, draw hypotheses about how things work in the real world, make films or sculptures, or just have madcap fun.
While the toolkit and physics engine are superb, GMod is nowhere near as easy to use as its spiritual cousin, Minecraft. If students don't already have experience with similar editing software, they'll need to spend a significant amount of time learning the ins and outs of the game's tools, materials, and settings. GMod also has some highly distracting assets –- weapons and scary, rag-doll character models -– which, like TNT in Minecraft, might derail more productive play.
As a teaching tool, GMod benefits from focused use and clear expectations –- including what specific objects should be used. It's definitely a "right kid, right time, right project" teaching and learning tool and unreasonable as a requirement for an entire class. But certain kids will fall in love and engineer fantastic creations.
Key Standards Supported
Modeling With Geometry
Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).
Apply concepts of density based on area and volume in modeling situations (e.g., persons per square mile, BTUs per cubic foot).
Apply geometric methods to solve design problems (e.g., designing an object or structure to satisfy physical constraints or minimize cost; working with typographic grid systems based on ratios).
Key Standards Supported
Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6–8 texts and topics.
Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic.
Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words.
Integrate and evaluate multiple sources of information presented in diverse formats and media (e.g., quantitative data, video, multimedia) in order to address a question or solve a problem.
Key Standards Supported
Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
Motion and Stability: Forces and Interactions
Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
