Developing a lesson for students to explore present and past technologies could look different for each year level. For younger year levels students could be exposed to different technologies, allowing them to touch, feel and see for themselves the differences. For example, students could compare an old phone from their grandparents years to a modern phone used today. As the students got older, they could create a memory match game, a model, or a presentation on the differences. For example, the students would put an old phone on one card and a new phone on the another, as they played the memory game the match would be the old technology with the new. Or for a model, they could attempt to build an old phone and have them include each of the details.
