First you build, then you battle! Punch up the “fun” in science fundamentals with the Explore Science Rumblin’ Robots. With this kit, junior scientists can learn the basics of circuitry as they build their own boxing robots. Once done, family and friends can have bot-battles to see who will become king of the ring. The kit includes individual scoreboards that allow players to track their own points and a boxing ring base that doubles as a storage box.

Explore the relationship between electricity and magnetism with this metal detector challenge set from Explore Science. Using the components, users can build a handheld metal detector with adjustable sensitivity, a mini security check station, or an aim and shoot challenge designed to demonstrate how parabolic motion affects detection. Users can also test their hand-eye coordination and learn basic circuitry principles by building a simple maze game.

Connect with key principles of electricity through this engaging STEM kit from Explore Science! With this preassembled circuit board, junior explorers can have a truly electrifying experience as they perform more than 50 detailed experiments involving elements like lights, sounds, magnets and touch plates. Users will learn basic concepts about electrical currents as they manipulate the wires to create light effects, animal sounds, alarms and more.   

Junior scientists can tackle 125 different circuitry challenges in this science set that truly amps up the fun. Learn simple principles of electronics by constructing a variety of challenges utilizing four main components — a mini aim and shoot basketball game; a bubble maker; a robotic dinosaur; and a maze game that can increase in difficulty with just a few bends of a wire. The set also includes multiple storage boxes that double as bases for your builds.

Engineer hours of fun with this build-it-yourself electronic science set! Junior scientists will learn the basics of circuitry as they design challenging maze games for friends, launch a flying disc, build a bubble maker and more. The set includes accessories for 14 different challenges and two multi-purpose storage boxes that double as bases for your builds.

Emerging engineers can get a great introduction to the wonders of mechanical engineering with the V8 Model Engine. Kids will learn how engines work — including the 4-stroke cycle — as they build a model version of a V8 combustion engine complete with vroom vroom sounds. This engaging kit includes more than 270 pieces as well as a step-by-step instruction manual.
