Some data, such as temperature, can be measured easily by students. Other data may require specialized instruments or creation of a special comparison scale. Whenever possible, students should use metric measurements in scientific investigations. You may wish to discuss how Lydia and Melissa could have improved measurement in their investigation. The data collected by the students in the video could be arranged on a map.
Spatial sense used in reading and creating maps is important in geometry.
Your students can practice geometric skills by creating their own maps of communities. Using triangles and one reference point, your students can create an reasonably accurate map of a small area. Evenly highly sophisticated GIS is based on the geometry of simple shapes like the triangle. When students collect data it should be organized in charts, tables or graphs. These forms of organization help us see patterns in data.
