Students started by comparing their PERT chart homework assignments, finding their errors, and producing a final shared PERT chart for their project. They learned how they can be used to get tasks in the proper sequence and to estimate expense and time-to-completion.
The kids brought in some fascinating current events for discussion. They absolutely nailed the intent of this part of our course: finding socially important topics (school fire, lost Malaysian plane, Ukrainian tensions, etc.) and highlighting the role that engineering plays (arson investigations, land-and space-based flight tracking, image processing, natural gas transportation, failure analysis, etc.).
It was such a good discussion that I let it run and delayed starting the next topic, but this means the kids will need to do some reading before our next session.
Homework for Next Session
Each week we will have two students choose the current events. Choose a current event and be prepared to explain 1) the event they chose and 2) the role that science plays in it.
Read the two articles emailed to you separately. One describes how photovoltaics work; the next describes the nature of light. These are tough topics. By reading about them ahead of time, our in-class discussion will make more sense!
