Before arriving at the pond, research common pond living organisms (such as snails, leech, water mites, spiders, water striders, newt, crayfish, water boatman, mosquito larvae, water scorpion, algae, dragon fly nymphs, duck weed, cattails, turtles etc). Upon arrival or prior discuss safety and protecting the pond rules. A good book to bring is the Golden Guide to Pond Life by George Reid. Scoop water into the basin and add any creatures caught with nets. Study and discuss. Share findings with other groups. Look with magnifying glass for smaller larva and insects. Talk about ways the pond provides food for wildlife in the area. Discuss ways to protect and care for local ponds. Release all creatures carefully before returning.
