I came across this video clip that features a fourth grade teacher sharing some great distance learning resources. I hope you will have time to check the video out at: https://www.youtube.com/watch?v=svmGQhQLuBQ
This particular teacher has several videos for distance learning.
You asked about advice for future teaching; I use the NSTA Library to store my science resources. It is easily accessible and no matter what school district I teach at, I will be able to have my 'electronic' file cabinet of resources at my fingertips. I now have over 300 resources (articles, book chapters, archived web semiars, etc.) stored in my library. I also have personal files I have uploaded through the years. I hope you will start to collect resources for your future science teaching! Best of wishes for a great, effective teaching career.
