This was one of the first assiments we were given for the first marking period. We had to pick four inventions of the 20th century. I picked the blood bank, the cell phone, the band aid, and the crayon. We had to name the creatier of the invention, the time it was created, and how it changed over time. It all had to be in a power point and noted in our engineer's notebook.
