Week One Summer 2010 Shortcourse : Math in Science Context: Assignment Questions Post Answers: "Questions for Thurs. 1) Why is power delivered via AC not DC? 2) Have you and your group decided on a topic for your lesson plan? If not, ..."
Thursday Questions
1. DC power would be too expensive to transmit through long distances. It would require heavy-gauge copper wire and require constant service for break downs. AC allows us to raise voltage while reducing current while transmitting and still be able to reduce the voltage to send it into individual buildings.
2. As we are doing individual lesson plans, I am giving thought to using the motion sensor application to help students understand graphs better.
