Give kids a fast and friendly introduction to speed, angles, and distances with the hands-on learning challenges of the Wacky Wheels STEM Challenge set from Learning Resources. This compelling physics-inspired activity set gives kids a seemingly simple goal—send the included launch balls rolling up ramps, over obstacles, through a target hoop, and into the goal cup. Once they begin, kids use trial-and-error play as they tweak the course setups, launch speeds, and other variables in search of a successful result. In addition to designers, kids are also the Wacky Wheels STEM Challenge’s prime power source—the set’s paddlewheel launcher operates without the need for batteries, rubber bands, or springs, giving kids hands-on lessons in force every time they send a ball flying. This set includes a full-color booklet filled with challenges both simple and complex, a combination that keeps kids (and adults) coming back for additional playtime. Ages 5+.
