Placing ourselves in the universe

Today's discussions were interesting, although somewhat above my level. Using a beach ball to demonstrate the galactic coordinates was very effective; I kept thinking of my years teaching latitude and longitude in 3rd grade and how students assimilate concepts more easily when familiar objects are used in lessons. I wish we had spent more time talking about GPS and the various satellites that are transmitting so many types of information. That would seem to me to clearly relate to Jeff's historical overview because it's the present and future of our use and sense of place. I enjoyed the microwave experiements but wouldn't have been able to remember/understand much of what we discussed without the concept maps that we created in small groups. Interacting with each other at different times throughout these sessions is one of the reasons I'm really enjoying this Institute.
