Title:

Code to Picture

URL:

Content Source:

PBS
Type: Interactive/Game

Overview:

Visualize the relationship between the binary code of 1s and 0s and an image with this interactive tool. Students can investigate relationships by testing how a code is used to create an image pixel by pixel and how the quality of a picture (its resolution) can be improved. A student assignment includes a brief reading to provide context on the code and an opportunity to test out a code with a partner.

Content Standard(s):
Science
SC2015 (2015)
Grade: 4
7 ) Develop and use models to show multiple solutions in which patterns are used to transfer information (e.g., using a grid of 1s and 0s representing black and white to send information about a picture, using drums to send coded information through sound waves, using Morse code to send a message).*

Unpacked Content
Scientific And Engineering Practices:
Developing and Using Models
Crosscutting Concepts: Patterns
Disciplinary Core Idea: Waves and Their Applications in Technologies for Information Transfer
Evidence Of Student Attainment:
Students:
  • Develop a model to show multiple solutions in which patterns are used to transfer information.
  • Use a model to show multiple solutions in which patterns are used to transfer information.
Teacher Vocabulary:
  • transmit
  • transfer
  • decoded
  • accuracy
  • digitized
  • convert
  • coded
  • signals
Knowledge:
Students know:
  • About digitized information transfer. (e.g., information can be converted from a sound wave into digital signals such as patterns of 1s and 0s and vice versa; visual or verbal messages can be encoded in patterns of flashes of light to be decoded by someone else across the room).
  • Ways that high-tech devices convert and transmit information. (e.g., cell phones convert sound waves into digital signals, so they can be transmitted long distances, and then converted back into sound waves; a picture or message can be encoded using light signals to transmit the information over a long distance).
  • Information can be transmitted over long distances without significant degradation. High tech devices, such as computers or cell phones, can receive and decode information - convert form to voice - and vice versa.
Skills:
Students are able to:
  • Generate multiple design solutions that use patterns to transmit a given piece of information.
  • Apply the engineering design process to develop a model to show multiple solutions to transfer information.
  • Describe the given criteria for the design solutions.
  • Describe the given constraints of the design solutions, including the distance over which information is transmitted, safety considerations, and materials available.
Understanding:
Students understand that:
  • Similarities and differences in the types of patterns used in the solutions to determine whether some ways of transmitting information are more effective than others and addressing the problem.
