Lesson 3
Lost at sea
In this lesson, students explore how error detection supports reliable global communication. Students build on their understanding of packetization from the previous lesson and investigate how packets travel along different routes and explore potential network failures. They then participate in an unplugged activity to analyze packet loss at local, regional, and global levels. Finally, students use conditional statements in Scratch to simulate packet delivery and detect transmission errors.
