A few years ago, whilst on a family holiday in Pennsylvania - we drove down to Philadelphia - and part of that visit involved a tour of the National Constitution Center. Well worth a visit - though as with many buildings at the moment - it is closed during the Coronavirus Crisis.
However the work of the Center continues. There are some excellent resources available online. I spent some time exploring what is currently available - and was excited at what was available. The website to go to is https://constitutioncenter.org
I was particularly impressed by the range of videos available - which you can access here.
