Morse Coding

GRADES 6-8

power board

Project Description

Students explore the history of human communications from cave drawings to wireless devices. They replicate a traditional wired telegraph, study Morse Code and use it to communicate information with other students within the classroom, learn about wireless communications and how to create a device that acts as a “wireless telegraph,” and explore how radio waves can be used to transmit and receive information. As they develop their devices, students learn all about circuits and electronics and use them to wirelessly communicate with each other.

Summary of Standards

GRADES 6-8
Computer Science Teaching Association Standards (CSTA)
Students will model how hardware and software work together; create clearly named variables that represent different data types, design and develop programs that include nested loops and compound conditionals, and model how data can be transmitted across networks.

Common Core ELA

Students will learn new content specific vocabulary, participate in collaborative group discussions, and respond to questions related to the topic of discussion.

Next Generation Science Standards (NGSS)

Students will determine the factors that affect the strength of electric and magnetic forces; use mathematical representations to describe a simple model for waves; and integrate qualitative scientific and technical information to compare digitalized signals and analog signals.
