Overlays are datasets with transparent backgrounds that contain foreground data used to augment other SOS datasets.This particular dataset overlays arrows and names of the approximate prevailing wind onto any dataset that you are viewing. General circulation overlay would be particularly useful when pointing out the rain shadow effect as well as cloud movement or when describing the coriolis effect.
Overlays can help provide context for your audience and make the datasets easier to understand, as well as provide information that may be useful to illustrate related global ideas.
Overlays are accessible on the SOS Remote app for iPad/iPhone/iPod Touch on version 4.0.2 and above.
Simply tap the Overlays button in the upper right hand corner of the Presentation tab to open the list of available overlays. Note that Overlays may also be pre-programmed into a playlist as a layer.
C7 Stability and Change. Students explain stability and change in natural or designed systems by examining changes over time, and considering forces at different scales, including the atomic scale. Students learn changes in one part of a system might cause large changes in another part, systems in dynamic equilibrium are stable due to a balance of feedback mechanisms, and stability might be disturbed by either sudden events or gradual changes that accumulate over time
