I was asked to do a primitive technology class for the 4th graders where I work. I decided to talk to the kids about stone tools, bow drill fire, bows and arrows and brain tanning hides to make clothing. I am going to try to explain that mankind has always engineered solutions to meet our needs and just like back then, Today's technology will sometime in the future be viewed upon as "primitive". The class is on Wednesday morning. Everything packed up and ready to go. Wish me luck!
