Teaching Tips

Teachers must come up with their own strategies to make use of this tool by either creating a lesson around this information or carefully inserting this tool into a unit.

While these diagrams may be initially difficult for some learners to grasp, a careful initial walk through followed by "pair and share" can help make the basic "spaghetti diagram" logic easier to understand.

These flow charts can be used in an energy unit with a well-crafted inquiry and discovery project that guides students through a global "compare and contrast" worksheet/exercise where they can construct their own conclusions.

Educators will want to discuss impact of population, geography, and seasonal variability on the magnitude and timing of energy use.
