As part of the 2013 4-H National Youth Science Day Experiment I am interested in knowing if there is a way to create a geocaching game without the use of GPS electronics devices. Other game or experiment ideas include:
Navigation and location
Observation and data collection
Mapping to find solutions
Photo interpretation/remote sensing
The goal is to get kids comfortable with the idea of geo referencing without the expense of using electronic devices. Your thought son this would be helpful, thanks.
