While many ideas circulate with great things your family can do during this COVID-19 crisis, my favorite is the time capsule. This is a huge worldwide historical event, and most of us have some time on our hands. There are some PDFs floating around with options to complete some prompts regarding how your family handled this event. The only one I have seen is a PDF that really is geared toward elementary students.
I just started a shared Google Doc with my family. I started the document with categories such as business, church, schools, medical, society, etc. and gave just an overview of how those various entities responded to the virus. I then got personal with how our family spent our days and how we were impacted. My hope is that Andy and the kids will each add their own experiences to the document. I plan to convert this to a PDF and then add it to our Forever storage for future generations of this family - or for us to consider down the road.
Just an idea. Don't forget to add things like your current age, occupation etc.
