Activity (Hands-On)Grades 6 - 8
Mountain Rescue: Transmitting & Receiving Code Messages
A QR code is an example of coding with stored messagesCopyright https://en.wikipedia.org/wiki/QR_code#/media/File:Wikipedia_mobile_en.svg
Students become familiar with the concept of a communication system, its various parts and functions. To do this, they encode, decode, transmit, receive and store messages for a hypothetical rescue mission, using a code sheet and flashlight for this process. They also maintain storage sheets from which they can retrieve information as it is required.
Coding and decoding make up a significant portion of electrical and computer engineering. Engineers design hardware and software for many devices such as radios, televisions, cell phones and computers that use one or both of these processes.
After this activity, students will be able to
- Understand digital data transfer.
- Understand the process of encoding and decoding.
- Understand the parts used in a communication system.
