My daughter today, trying to catch as many water striders as she can in a local park, and count the ones she carefully marked with white-out last week. She's doing her senior year of college remotely and this is a water quality lab course she's doing online, from home. I'm impressed with how well her professors are teaching her remotely. She caught and marked about ten last week, and was able to catch eight this time, three of which were marked.
And on a camping trip over the weekend.
