GIS K-12 in Delaware Schools Presented by Nicole M. Minni
Overview • Map Projection Basics • Creating Orange World • Summer Vacation Atlas • Fun in the sun with GIS
Projecting the Edible Globe • What is map projection? • The earth is a spheroid and to make a map you must represent it on a flat surface • This is accomplished by a mathematical transformation called a map projection • Map projections distort shape, area, distance, and direction. Some projections preserve one of these properties at the expense of others. • Uncontrolled • Controlled
Projections, continued • Sinusoidal • Countries are increasingly distorted away from the central meridian(s) and near the poles • Lambert Conformal Conic • retains conformity, distances true only along standard parallels, directions reasonably accurate, distortion of shapes minimal, but increases away from standard parallels • Robinson • better balance of size and shape of high latitude lands, but greatest distortion is near the poles • Mercator • preserves direction, but distorts shape Your choice of map projection allows you to control the type of distortion in a map for your area of interest.
Summer Vacation Atlas • Range of the project is the entire school year and relates to all areas of education • Math - measurements/calculations • History - Cape Henlopen Light House - WWII • Science - hypotheses • Biology - mollusks • Environmental - data attributes, overall care of beach • Reading and writing - report on activities, observations and conclusions.
Where to begin • Ask children what they want to discover about the Delaware Beaches • Possible responses are: • What beach is best for collecting shells? • What beach is best for collecting drift wood? • What beach is the trashiest? • What is the foam color, water color? • What beach has the best waves? • What beach is the widest? • What direction do the waves break on the beach?
Data Collection Sheet • Hand out data collection sheet • Select your first beach to visit • Gather as much information that you can while you are at the beach • take digital photos • complete data collection sheet, need clipboard • GPS unit, if available
Map Your Results • Open appropriate themes • Add data and attribute information • Review your analysis • Report your results • What is your favorite beach and why? • How did this study assist in your conclusions?
