While on a camping trip, Jesse finds a curious piece of stone with an interesting pattern on it. With research and the help of Professor Peach, she learns that it's a piece of broken pottery with a pattern unique to a certain Native American tribe. After an archeological dig with the Professor and her friends she finds more pieces of the ancient artifact. Using her art skills, Jesse is able to preserve the clay pot. Ten-year-old Jesse Steam’s curiosity about how the world works leads her to one mystery after another as she pedals around town, often with Mr. Stubbs, her tabby cat, keeping her company in the bike basket. Using simple scientific tools and their powers of observation, Jesse and her friends analyze, test hypotheses, and conduct experiments. If the kids get stuck, they know they can count on Professor Peach, a retired college science educator, to step in with a clear explanation. Jesse STEAM Mysteries promote STEM and STEAM concepts for young children.
