artifacts of a subculture

Three of the artifacts from the subculture that I am looking at are:
5th graders technology items such as the smart board, netbooks, IPads
School items : books, pens, desks, paper, lockers, crayons, markers
Outside objects: balls, jumpropes, footballs, other objects that they play on or around
some of the these objects I know a lot about such as books, pens and papers, and computers, but the smartboards, what are those?
I know about balls for playing baseball and football, but what about 4 square and some of the social games they play outside?
I hope that knowing something about some of the artifacts a 5th grader uses will not affect my interpretation of them until I actually go and watch them for a day in their environment.
The artifacts in their lives are important to them especially the outside items, as recess is important. It seems like the way they dress, some of the school supplies they have will say a lot about where they fit in and belong. I will hope to see this in my observations. I could research somewhat about the technology now being used in a typical elementary classroom and what some common playground games are. I could research the developmental level of a 10-11 year old.
The three most important things this artifact tells me about this subculture are this is a new generation of students who are learning in different ways than I did when I was in 5th grade because they now are learning in new ways in a modern world, yet I think I will find some of the same games played on the playground that I played there over 15 years ago.
