Hi, it’s Caroline the Curvy Line with a short fact about lines:
A line can be straight or curved. A straight line is a line that does not curve, while a curved line is a line that bends or arcs.
Hi, it’s Caroline the Curvy Line and Scott the Dot! Today we’ll learn about Morse code – a system of communication that uses dots and dashes to represent letters and numbers. It was invented in the 1830s by Samuel Morse, and here’s how it works:
Each letter and number is represented by a unique combination of dots and dashes. For example, the letter “S” is represented by three dots.
To send a message using Morse code, you would tap out the dots and dashes using a device such as a telegraph key or a flashlight. The person receiving the message would listen or watch for the dots and dashes and translate them back into letters and numbers.
