Introduction to Current calculations

Based on a handout for grade 9 science to introduce how to calculate current, charge, and time. At this point, we have already introduced all the components of a circuit, including the idea of current as number of coulombs per second. We have already spent time setting up similar density calculations, so the format of the solution doesn't need much explanation. This was originally intended to be an asynchronous introduction, to be followed by a video showing examples of finding I, Q, and t. It is self-pacing; students can't skip ahead until they have submitted an answer. The second last screen is a check-in if students are having too much difficulty. The drag and check current calculation screens were modified from John Rowe's Open Middle templates: https://www.desmos.com/calculator/dvy9lpozkz
