How about exploding popsicle stick bombs? I would think the kids would pay close attention to make sure they put the sticks together right. It’s not hard, they’d just have to follow the directions. My kids used to love these. I still occasionally find random lost popsicle sticks. https://frugalfun4boys.com/build-popsicle-stick-bombs/
Otherwise, how about post-it note origami? Stars and tulips are fun and easy. There are a lot of Pinterest links to different kinds.
But honestly, I liked pp’s idea of the scavenger hunt. My daughter did that with her BSA scout troup and it held her attention, it had the kids running around and laughing and comparing online what they found. Everyone was given a list of objects to find in their house and 15 minutes to gather them and show them to the zoom group. Then I had to put it all away.
