In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion. Since this activity requires some passage of time for a noticeable change in shadows, it is best done at the beginning of an event or a series of activities so learners can revisit their tracings after a period of time. At museum or planetarium settings, this might be a good activity to set up at the entrance for visitors to do at the beginning and end of their visit.
