Latitude, Longitude, Styrofoam, & Apples

Here's a neat little activity that I came up with for Jenna to help with learning about longitude, latitude, the equator, etc.  She painted a styrofoam ball to look like Earth.  We put a chopstick through as the axis.  At that point, we were able to label the North and South Pole, and then cut on the "imaginary" lines to talk about the equator and lines of latitude.  We cut up an apple using an apple corer/slicer to talk about the lines of longitude, the Prime Meridian, the International Date Line, as well as regular meridians.  At the end of our activity, I was able to reinforce the discussion with a question/answer session.  With all the correct answers, Jenna got a slice of apple to eat.  It was actually pretty fun!
