Hannah Archibald, left, is watched by, from right to left, Adeline Runnels, 8; her mother, Heather Runnels; and Ellen Gawarkiewicz as she adds an abdomen to a collaborative drawing of an insect during the Science Explorers program at the Lewiston Public Library on Wednesday. The drawing was a game used to familiarize about a dozen children in attendance with the parts of an insect's body. The program meets from 4 to 5 p.m. every Wednesday for six to 10 weeks and has covered an array of subjects from "Vampire Science" on Halloween to the digestive tract. For more information, call the Children's Desk at the Lewiston Public Library, 513-3133.
