Prisoner of Echo Teacher Guide - Unit Introduction

Unit Introduction


Thank you for choosing Filament Games' Prisoner of Echo, a game that teaches students about the properties of sound. In the game, the player is trapped in a space-mine on "Asteroid 60 Echo," which is patrolled by robots gone haywire. These bots rely exclusively on sound to navigate their surroundings, communicate, and detect escapees. To foil the sound bots and escape the base, students must use their wits, their knowledge of properties of sound, and a Sonic Visualizer—a special device that allows them to see sound waves.

This game is designed to be used in inclusive science classrooms that have a diverse range of students (e.g., average and above average students, students with high incidence disabilities, English language learners, and students who struggle with reading). It is designed using the Universal Design for Learning framework and is strategically aligned to Next Generation Science Standards.

This curriculum package includes two lessons and a written assessment to help you support your students while they play Prisoner of Echo. Be sure to familiarize yourself with the game before your students play. The beginning of the game acts as a friendly tutorial that walks you through the background story and basics of the game. The lessons extend the game-playing process through a lab, discussions, and a written assessment. The lesson worksheets can be distributed as printable handouts or they can be projected on a whiteboard.

Prisoner of Echo Learning Objectives

  • Describe wave interactions including interference, reflection, refraction, and diffraction.
  • Describe the characteristics and parts of sound waves.
  • Explain the Doppler effect.
Most importantly, enjoy Prisoner of Echo and have fun!

Standards Map


  • MS-PS4-2

    Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
  • PS4.A: Wave Properties

    • A sound wave needs a medium through which it is transmitted.

Common Core

  • CCSS.ELA-Literacy.RST.6-8.3

    Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
  • CCSS.ELA-Literacy.RST.6-8.4

    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.

Benchmarks for Science Literacy

  • 4F/M4

    Vibrations in materials set up wavelike disturbances that spread away from the source. Sound and earthquake waves are examples. These and other waves move at different speeds in different materials.
