The ToddCast - Over Time (Depth and Complexity)
Over Time - 1 of the 11 icons in the Depth and Complexity thinking framework, this is a complexity icon that takes a look at how things change (and sometimes do not) change over a given period of time. This might be an hour, it could be years, it could be centuries. Because it is such a complex idea to grasp, using as many concrete and specific examples as possible can help students to see how over time works. This is especially important for those studying history in determining how and why things have changed (ideas, technology, beliefs) over time.
