It's a beautiful day in Deanville and the gang is presented with a new challenge. How will the kids solve this difficult new task? And how does a Greek mathematician play an important roll? Think like an engineer and read The Mighty Lever Endeavor to find out. Ten-year-old Jesse Steam's curiosity about how the world works leads her to one mystery after another as she pedals around town 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 science educator, to step in with a clear explanation. Jesse STEAM Mysteries promote STEM and STEAM concepts for young children.
