First we built compasses to discover where north was. We magnetized paper clips, then needles. We tried suspending them with thread and floating the needles on small pieces of cork. Floating worked better.  We used the compasses to find magnetic north.

Once we knew where north was, we built sundials! We used the sundials to determine the time… once we had waited more than two weeks for a sunny day!  The sundials were pretty accurate and we were also able to use the sundials to determine direction once we knew what time it was. The sundials will be coming home today!

Mad science!
