Use orders of magnitude to judge the significance of resource data. (MS 2h)

In the subtopic Using the Earth's resources and sustainable development, this learning objective focuses on use orders of magnitude to judge the significance of resource data. (MS 2h). Within Using the Earth's resources and obtaining potable water, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include 2h. orders of magnitude means a way of comparing quantities by their powers of ten to assess their significance. Avoid students often confuse orders of magnitude with simple numerical values, failing to recognize that orders of magnitude represent a scale of tenfold differences; instead to fix this, practice converting numbers into scientific notation and understand that each increase in order of magnitude represents a tenfold increase. For exam answers, practice converting resource data into orders of magnitude to quickly assess their significance.
