What is technology?

Today we started our first big engineering unit of the year by talking about exactly what an engineer is (hint:  they don't just drive trains!) and what technology is.  We learned that engineers use science, math, and creativity to design solutions to problems and to improve things so they work better.  Then we looked at some examples of technology I brought from my house and they worked with a partner to decide what problem this technology solves and what materials it is made of.  Here are some hard-working scholars with their technology.
