Activity: In this activity children would be given an opportunity to compare how the communication devices have changed over the period of time. There are two options by which children can compare new communication and latest communication. I would create a QR code for the students to watch a video about how communication has changed over time. The second activity would be that I would bring in an old and new form of communication eg. Old phone with dial and then a iPhone. Students can record their compare and contrast on the Explain Everything app on the iPad.
