If anyone is still looking for summer camp options, Mad Science has openings at their Sharpsburg satellite lab. I know finding things for the younger kids to do has been harder with more COVID restrictions and they are taking grades K-6. The website is:
www.pittsburgh.madscience.org. You can use the discount code for PPS for $25 off too. Feel free to share with anyone you may know is still searching! I'm not affiliated - just happy to have found something my 5 year old can do!
