It’s a breezy new day and along with a tempest in a chocolate milk glass, Jesse’s presented with a messy new mystery when Dorky Dougy loses his lunch while spinning on the merry-go-round. The big question is, why did the ballistic barf fling outwardly, as Dougy spun? Read The Question of the Vomit Vortex and learn all about these centrifugal and centripetal forces! 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.
