Excellerations Junior Engineering Activity Set

GET A HEAD START ON STEM: This 220-piece kit gives kids everything they need to imagine, design, construct, and problem solve. Components include planks, nuts, bolts, and cubes for creating 2- and 3-dimensional structures. REPLICATE OR CREATE: Kids can unleash their inner engineers by building the structures shown on the 5 double-sided activity cards, or they can create their own imaginative architectural marvels. SIZED JUST RIGHT: Largest pieces are 7-1/2 inches. Nuts and bolts are small enough to be a realistic representation, but big enough for kids to handle. KID FRIENDLY CRAFTSMANSHIP: All pieces are molded of easy-clean soft plastic with smooth surfaces and rounded edges. Storage bin included. Recommended for ages 3+.
