Another ELD strategy is to use props, realia, and artifacts, which could be included in a table top timeline. This suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not the first coronavirus to cause a pandemic and, given the frequency of outbreaks (SARS-CoV in 2003 and MERS CoV since 2012), it is likely not the last one.

Multiscale PHATE exploration of SARS-CoV-2 data reveals multimodal signatures of disease. They had to take on more responsibilities at home, including childcare and eldercare. Research shows that even young children have an understanding of temporal order of events in history and have the ability to think about and try to explain continuity and change over time (Barton, 1997, 2002, 2008; Barton & Levstik, 1996; Downey & Levstik, 2008; Harnett, 1993; Levstik, 1991).
