ACTIVITY: Learn Morse Code

NGSS Science and Engineering Practices:

NGSS Crosscutting Concepts:

The activity below draws from the content in the page Patterns to Transfer Information.

Phenomenon:

We can communicate with our friends and family from far away.


Inquiry:

How do our phones send information?


Guiding Questions:

  1. How can patterns be used to transmit information?

Activity:

Learn morse code and practice sending messages in different ways over a distance. 


Materials:

  • Student worksheet and teacher answer key (attached below):
  • Flashlight
  • Pencil
  • Paper
  • String
  • Tin cans (x2)

Teacher Recommendations:

  • Different thicknesses of string may send signals of variable strength. You can use different strings per group and rotate, experimenting with their effectiveness. 
  • It might be beneficial to split the groups so some use the flashlight first while others are tapping or knocking (this way you donʻt have a roomful of students knocking!).

Procedure:

  1. Follow along on your worksheet to conduct your trials and answer questions.
